Bikeray IV, Magicshine MJ808E and misc light beamshot

I received a new Bikeray IV and a new Magicshine MJ808E XML. I used for about a week now and pretty impress with the two unit working as a combo. The BR IV is on the handlebar and the MS XML on my helmet. The BR IV throws out some impressive light with plenty of flood and yet also some throw but without a hotspot. The Magicshine MJ808E XML is for sure a thrower with a hot spot and little flood.

I decided to take some beamshot of the two lighthead but also did some other lights and flashligt to show the difference of beam and lumination of some of the light I used. There is a lot of option for light and flashlight and I hope this can help those who are looking and deciding. So I decided to add in some beamshot of my other lights just as a FYI.

The light test and setup can be see here and here.

The setting consist of a can set out at 100ft distant and behind that is a concrete block at a distant of 150ft. Two trees are closer to show the flood. The camera setting is as follow: Iso 200, Fstop 4, Shutter 2sec.

Here is a control shot:




This is a beamshot of the Magicshine MJ808E XML




This is the beamshot for the Bikeray IV




This is a combo of the MS XML and Bikeray IV. I've used this setup for a week now on my commuter bike and thought it will be an overkill but so far I have yet have any motorist highbeam me or honk at me.




For comparison of a Magicshine P7




The Gemini Titan beamshot is here

Deal extreme P7 flashlight is here

Shiningbeam MG P Rocket XPG R5 flashlight is here

and finally a Shiningbeam S Mini XPG flashlight is here

Colleen, thanks for the beam shots. To my eyes, it looks like the BR4 has a wider-angle beam then either of the MSs. Is this true?

Socalrider - I have read the BR4 uses XPG, which is what DX specs state for the MS872:

http://www.dealextreme.com/p/mj-872-...pack-set-80953

Looks to be much the same light as BR4, minus the accessories. BR4 is probably as good a deal once accessory costs are added to the DX MS872 price, plus dealing with a US seller.

The Led type is a good question. When it came out 1-2 weeks ago, I saw the the listing on the Bikeray USA site as Philip LED. Since then it is not listed anymore. I had the lens off of it and it did not look like a XPG Led. The package is more of an retangular shape rather than a square shape whick is what I seen of most Cree XP-G LED used in flashlight. I took a picture of the LED.

There are some difference between the MJ872 and the BR IV. The MJ872 has a listing runtime of 2hrs with their pack rated at 4.4 Ahr. Interesting note is that I used the 5.2 Ahr battery that came with my BR IV light and I ran it with my Magicshine taillight on blink mode and timed the runtime. I got 2hrs and 35min of runtime on high with the MS blinking. Bikeray claimed their battery will last 3hrs 30min on high. So far customer that has this light are getting 3hrs 15min. I'm confident that with a 4.4 Ahr pack I can get more than 2 hr of runtime as compare to the MJ872.

The beam of the BR IV is wider for sure. When I first turn it on inside the living room, I was not impress with the beam angle, that was until I took it out the next day on my commute. First thing I notice is that it shine further up the road than the MS 900 and even farther than my Gemini Titan while not having any Hotspot. The second thing I notice was how parked car was much better lit. Well enough to see a door flying open before I get to it. It was almost nice enough of a beam that I can almost see if there was a person inside the driver seat of a parked car while riding at 14 MPH and staying within three feet of the car.

Bikeray USA does have a listing for the BR IV head only for $125. That mean you can get the head only and use your older Magicshine battery since the connector will fit. You can find it at their web listed under parts and accessories .

Its the Philips luxeon rebel. Probably the higher output ES version.

The BR4 must have a very nice beam. Thanks for the link to light-head-only, I hadn't noticed it before.

Wow, BikeRay is selling 5.2ah batteries for 30 bucks! I wonder if they're any good.

Does the BR4 have a flash (strobe) mode, and if so, can you estimate rate? The BR4 website lists mode as SOS, which I find less useful than a ~2hz strobe.

You are correct, sir. Colleen's led picture matches the graphic on the Luxeon Rebel datasheet.

After reading the data sheet, I'm wondering what emitter/bin BikeRay is using, the current, and overall output.

Thanks Znomit. The Led in my BR IV closely resemble the Link you provided of the Philip Luxeon Rebel.

I too was a little surprise to see a 5.2 Ahr battery at that price. The battery looks pretty decent. The shrink wrapping looks better than the generation 1 MS battery.

I took my best shot at counting the strobe. I counted 58 blinks in 31 seconds give or take a few I misses. It is a on/off blink and not SOS. The blink mode is very useable. I will eventually provide a video of the strobe.

Thanks. That makes sense - whoever designed the BR4 seems to know what they're doing. Now if they could just go to work on their website.

Bikeray IV blink mode Video. The beamshot on the left is from a MTE P7 from DX on High mode. The beamshot on the right is from a Magicshine 900 on High mode. The blinking strobe is from the Bikeray IV.

Finally someone who realizes that an uber fast strobe is not necessary and is actually dangerous at times.. May be looking into getting a bikeray this summer.. I count the strobe to be in the range of 140-150 pulses per minute, perfectly fine..

I use to use a 1w luxeon headlamp that strobed at 120 per minute and it was great for being seen at night..

It seem most manufactor are going away from that SOS strobe My Magicshine XML from Bikeempowerment has a nice timing on the strobe also. It is a simple Hi-Med-on/off strobe- off.

One disadvantage of the BRIV strobe is that the light is bright. If I use it as my only stand alone light in the strobe mode in the darkness, the flashing can get irritating. It's not too bad if I have all my other lights on high. Sort of imagine a HID headlight on a car flashing while driving. Now imagine that same scenerio but with some supplement light like a Fog lamp.

Yesterday was shower and overcast. I used the strobe on my way home. Pedestrian did take notice more so than before. There is a four way stop intersection at the Mall plazza street where it is really busy with cars. I watched the drivers reaction and notice how they turn their head and looked over at me. I think this make a good overcast, dawn, dusk strobing light for commuting.

There are one cons with the lights so far, the "green eye monster" indicator light is huge. About the size of a nickel but with the indicator light on, it looks like the size of a silver dollar coin. It's bright enough to use as a night light in my living room. Luckily, most of the time it's in the blue color as the battery drain and the blue is more mellow.

Thanks for posting these Colleen. Looking at them reminds me of have far lighting has come in the 5 1/2 years since I resumed riding, and how the Fenix L2D was the big thing when I realized I needed to get more serious about lights. One of the forum members bought 4 of them when most of us only had 1, and that was an amazing amount of light then. Now I wonder if the L2D is even working when I compare it to the 1st generation Magicshine I use.

For sure we came a long ways from the 100's lumen and now we're into the 1000's. I think in terms of more Lumens wise, doubling up two hi power 1000+ lumen lights is about the point of diminshing return. Right around 2000 to 2500 OTF lumens is right where it make no difference if I add more lights. My eye will start self adjusting. For me to see any difference, I have to aim those lights either more sideways or farther out instead of all in the same spot. The technology for brighter light is advancing to the point where now they probably need to start R&D different reflector or lens for spill and throw. One thing for sure, it's going to be a brighter future.
