Here is a recent on-point post purchase user experience based review that I recently shared with members on mtbr.com and now for any others uncertain about the lightset product's application "in the field" here on bikeforums with their members and other potential MS users.

Ordered the Magicshine P7 Based High Power LED Lightset Engine from Geoman. Order was processed promptly and accurately by Geoman. I am upgrading from a slightly dated led lightset in the form of a Princeton Switchback 1; so this will be a significant upgrade in terms of overall light lumen intensity.

I have seen some very good posted beamshots of the P7 Based Magicshine LED Lightset from a search on the internet; some very impressive looking illumination shots. I am willing to give the Magicshine MJ-808 high power led lightset the same chance I did with the Princeton Switchback I; as it looks like a great potential High Power Bicycle LED Lightset engine in the under one hundred dollar category.

As soon as I get the Magicshine after it ships from Geoman, I will factually share information of first product LED lightset impressions and in the field LED lightset impressions.

I got the Magicshine P7 Based High Power LED Lightset Engine from Geoman, the day after Columbus Day. Geoman by the way threw in the helmet mount as an added unexpected bonus to the Magicshine P7 based LED lightset kit. Many appreciative thanks to the Geoman or "G" Man for short.

I measured the Magicshine P7 based LED lightset head diameter dimension and it comes out to 1.5 inches and is 2 inches in lighthead depth for those concerned about it being bulky and/or heavy it definitely is lightweight as promised. The pushbutton on the back of the Magicshine LED lightset is about the size of a dime and is lit up with a green glowing LED when plugged into the 4.4aH Lithium Ion based battery pack.

The Magicshine lighthead bezel has a cool scalloped bezel design that makes it look very modern in styling. The Magicshine lighthead body behind the lighthead bezel has a concentric grooved cooling ridged design, with a professionally black anodized aluminum surface to help cool the LED lighthead.

The Magicshine lighthead power cord that goes to the external Lithium Ion based battery pack is a generous 45 inches long to allow the flexibility of mounting the battery pack wherever convienently desired.

If you enjoy the appearance and physical body design of the Lupine Tesla design this looks similar in most aspects and you will definitely like its cool, streamlined, sleek, modern, lean body based looking Magicshine LED Lightset design overall.

The Magicshine external Lithium Ion battery pack is 2.75 inches height tall body and has side dimension of 1.5 inches on each side; so it is relatively small and lightweight with a nylon pouch included to allow one to wrap it underneath the handlebar near where the LED Lighthead is to be mounted on the handlebars.

The Magicshine P7 based lightset kit also comes with an AC adapter designed specifically to recharge the Magicshine Lithium Ion based external battery pack rapidly/quickly and its DC output voltage is listed as 8.4VDC so as to enable the rapid recharging of the 7.4VDC external battery pack at a current rate of approximately 1.8aH.

The Magicshine external Lithium Ion battery pack only took about an hour to top off its charge and turn from the red glowing led on the Magicshine recharging AC adapter to a green glowing led.

I followed the included Magicshine yellow instruction sheet supplied by Geoman which clearly outlined the simple and self explanatory procedure to follow to cycle through the various five modes; the high, the med, the low mode intensities of illumination, along with the high frequency flash mode setting and the final strobe mode setting before going back to totally turning off the Magicshine LED Lightset completely.

The Magicshine black latex mounting o-rings included are sized 1.5 and 2.0 inches respectively and the thickness of the two black latex mounting o-rings included are both 3/16 of an inch thick which looks like it can be bought at any local hardware store having black latex o-rings available or at geomangear for $4 for the small/large o-ring paired 1.5/2.0 inch o-ring set.

The included Magicshine yellow instruction sheet also notes and mentions information regarding the Magicshine lithium-ion battery which should last approximately 300-500 charge/discharge cycles typically.

The Magicshine instruction sheet also mentions the lithium ion battery pack prefers partial discharges as opposed to full discharges to lengthen, optimize and enhance the lithium ion battery packs longevity.

The Magicshine lithium ion battery pack prefers to be discharged no more than 60% of total capacity:

4400maH times 0.60 equals 2,640maH.

This would be equivalent to approzimately two and a quarter hours on medium(500lumens) illumination setting as a conservative estimate or alternatively one and three quarter hours on the highest illumination setting.

If one needed additional battery capacity requirements on the day of bicycle tour or ride as a battery backup or extension to battery reserve capacity; Geoman has spare/extra Magicshine Lithium Ion battery packs for approximately $40 per extra battery pack; also as well.

This is altogether, not a bad idea as in the colder upcoming autumn weather Lithium Ion battery pack capacity may be compromised by at least ten percent or more in total run time/capacity.

I will be taking the Magicshine P7 based lightset out on the local streets where I live with an outside temperature of about 48 degrees F here in New Jersey, so running the lightset on the highest lumen P7 LED setting for about an hour or so in order to test the overall general lighting and beam width/depth/quality first impressions.

I will also use the Magicshine helmet mounting option first as Geoman was so generous to have included it in the Magicshine lightset kit; so I figure I might as well test that also as well at the same time as testing the Magicshine Lightset overall.

Its was fairly easy and relatively self explanatory to use and mount the large two inch diameter black latex o-ring around the horn on the base of the Magicshine LED Lightset and then thru the helmet mounting base and the other end of the o-ring around to the other side of the horn on the base of the LED Lightset to secure the Magicshine Lightset engine securely.

The 3/16 of an inch thick black latex o-ring can best be fitted on the front horn best by first removing the small phillips head screw to facilitate the temporary removal of the black anodized aluminum base of the LED Lightset to initially set the black latex o-ring in its assigned channel due to the fact the front mounted lightset wire temporarily obstructs the path for securely inserting the black latex o-ring for its initial placement position in its channel/lip.

An investment in a quality P7 based Lightset is an investment in confident, safe and enjoyable nightime cycling. With that being said I will go into some amplifying details on some firsthand impressions of the Magicshine P7 based Lightset.

I definitely will have to say that the Magicshine P7 based Lightset Engine Kit is a very complete and impressively well put together kit; for the under the sub $100 category P7 based Lightset Engine.

The minimal very compact footprint profile and total weight of the Magicshine lightset engine is sufficiently small that one can easily put two Magicshine Lightsets on ones helmet at the same time; as the lighthead is only about 240grams in weight along with its similarly lightweight and minimal 200gram external Lithium Ion based battery pack that is easily tucked away in ones rear cycling jersey pocket.

The forty-five inch cord from the Magicshine lighthead that goes to the external battery pack is sufficiently long so as to easily reach ones reach ones rear cycling jersey pocket conveniently.

The dime sized rubber covered green glowing switch on the back of the Magicshine lighthead has a nice tactile feedback quality and feel to it. The build qualty of the Magicshine lighthead itself is decidedly excellent and solid in both feel and looks; which is very easy on the eyes due to the sleek black anodized coating on the lighthead's surface.

I went for my first ride last night with the Magicshine P7 based Lightset mounted on my helmet with the supplied helmet mounting bracket from Geoman. The Magicshine helmet mount has a nice and great lightset head tilting adjustment feature that makes it easy to vary the vertical tilt angle evenly and smoothly in a controlled manner using only one hand; even while riding ones bicycle.

Kudos and many thanks to the Geoman for doing his homework and getting this Magicshine helmet mounting bracket for his loyal and faithful customer/users; as I am sure that they will fully enjoy its exceptional utility and safety options it potentially offers to Magicshine Lightset users/customers.

The Magicshine lighthead's beam quality is absolutely superb and can be best described as a "intensely well defined white and very bright high intensity clean beam of light";

with just the right amount of evenly divided spotlight; which threw out a very bright relatively far reaching clean symmetrical characteristic spotlight beam centric type of light beam pattern that reaches out to about fifty feet or so in front of the bicycle; thus providing a decent swath of light to illuminate the roadway ahead.

The Magicshine's other accompanying component floodlight characteristic light beam pattern provided healthy and generous amounts of needed desired spillover floodlight just outside the spotlight's corona outer illuminating area(very workable/usable light).

While the Magicshine Led Lightset is not as bright as a 13watt HID Bicycle Lighting System level of brightness, intensity and illumination; it is still nontheless still a more than adequate illumination tool to ensure safer nighttime cycling for the average cyclists nighttime cycling illumination needs.

Also, remember the cyclist always has the option(at a later time if needed) of adding yet a second additional upgrade Magicshine Led Lighthead which would bring the level of lighting illumination specification easily up to that of the 13watt HID Bicycle Lighting System if needed.

Also remember and note that, HID lighting systems does not have the capability of being adjustable in regards to the level of light intensity; unlike the Magicshine LED lightset which offers(high, medium, low, strobe, high frequency pulse) adjustability options.

The Magicshine Led Lightset also has significantly much longer Lithium Ion rechargeable battery run times also, as a result of being able to adjust its lighting to lower levels of light intensities(med/low); so as to conserve on battery power run times if needed as an added featureset.

Now being a user of the Princeton Tec Switchback I LED Lightset which is now a rather dated LED lightset; I just was not prepared for the light intensity in the Magicshine LED spotlight and floodlight quality arena.

In comparison to the Princeton Tec Switchback I Lightset this Magicshine Led Lightset is a spotlight and floodlight monster; as this is another level of bicycle lighting illumination altogether and will dramatically alter your nighttime cycling experience(s) at multiple level(s).

I was able to ride on my bicycle anywhere from approximately ten miles per hour on the flats to up to approximately twenty-two miles per hour on mildly sloping downhills with total utter confidence, safety and ability to see everything in front of the bicycle on the dark pitch black roadway.

As a result, I was able to rapidly settle into and enjoy my nighttime bicycle ride instead of worrying about being seen and also worrying about seeing what is in front of my bicycle safely. During the ride, I felt I never had to worry about slowing down for safety reasons trying to read the road subsurface at night for potential road obstruction hazards or dangers.

I will have to definitely say this is one powerful and intense updated P7 based LED torch Lightset put out by the folks over at Magicshine and can safely say I have never seen or experienced such a high quality level of bicycle lighting illumination before in a bicycle lighting system. Kudos to the Geoman and Magicshine people for a job well done; to successfully bringing this product to the bicycle lighting market.

I have no doubt they will have no trouble selling many more of these now updated Magicshine P7 based LED Lightsets once the good word of mouth advertising and good press release communications news gets out about how good the level quality of currently updated P7 based LED bicycling lighting system design has gotten.

During the one hour and fifteen minute nighttime bicycle ride the Magicshine Lightset was set on its highest intensity setting the whole time and the Magicshine Lithium Ion external battery pack did a fabulous job at maintaining this high level of light intensity without missing a beat.

Even after seventy five minutes of high light intensity being delivered to the Magicshine P7 based LED Lighthead, the level of light intensity remained high during the whole time without any signs of fading or diminishment in light intensity; thanks in part due to the Led driver circuit within the Magicshine Led Lightset.

I plugged in the Magicshine Lithium Ion external battery pack into its Lithium Ion based recharging AC adapter and it recharged the battery pack in about an hour without any muss or fuss about it; with the LED on the recharging AC adapter turning green after it finished showing it was finally done recharging the Lithium Ion battery pack.

One of the things that I noticed was that whether it was a long or short cycle(one hour or multiple hour recharge), the Magicshine Lithium Ion Battery AC adapter recharger always remained cool to the touch and the Magicshine Lithium Ion rechargeable battery also remained cool to the touch as well.

The whole Magicshine MJ-808 LED Lightset Kit is a well put together and thought out bicycle lighting system upgraded and enhanced with the newer P7 based LED Lighting technology which is now starting to be widely available and starting to enter the bicycling lighting system being now sold on the market.

Everything about the Magicshine P7 based LED Lightset offering from the LED lighthead mounting system to the LED lighthead beam quality and the LED lighthead casings modern and updated sleek black anodized looks to the advanced Lithium Ion based external battery pack subsystem design and its battery run time life is fantastic.

These are all potentially desirable invaluable bicycle lighting system characteristics and traits in purchasing a potential bicycle lighting system.

When I was contemplating purchasing this particular Magicshine bicycle lighting system I was initially concerned with all of the above discussed referenced items in this review.

I can safely say after having experienced firsthand this Magicshine P7 based LED Lighting Kit System will immensely add a much appreciated measured level of added bicycling safety and enjoyment to your next nighttime serendipitous bicycle riding road/mountain experience; at a fair value price that cannot be beat, to boot.

To the guys at Geoman/Magicshine; many Kudos/thanks for bringing this updated P7 based LED bicycle lighting system product successfully to cyclists worldwide via the internet; finally cyclists on a global wide basis have an alternative choice when it comes to selecting both a decent and very powerful P7 based LED Lighting System for their nighttime bicycle lighting system needs.
