Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

brightest headlight

is it possible to find a non-rechargeable front light bright enough to help me scan the road ahead even at downhill speed? i have used several brands with as many as 7 LEDs so far with poor results...At the moment i use a 5-LED bar mounted light and a 7-LED helmet mounted light and the best i can get is seeing the 15m of the road before my front wheel and then go totally blind for a while when i'm struck by the lights of an approaching vehicle. On the other hand i find that lights with battery packs are too heavy for the road especially if you have to carry them along for hours till it gets dark! Are there any bright and compact at the same time solutions that you've heard or used?

LEDs suck... they are efficient, but they suck. The spectrum of light they put out isn't what the eye is most sensitive to anyway. What you need is at least 19-LED to 30-LED lighs:




Much simpler to get one of these:


30-mcp cordless spotlight

The issue with using non-rechargable batteries is that it's going to cost you a tonne in the long-run. Especially when you get up to the power-output you really need, a set of batteries will last 1-2 hours max. Check out the Light selection guide and Total Geekiness.

There's a lot of conversation about this topic over in the Commuting forum, including a "Light Selection Guide" sticky at the top of the forum. Quite a bit more info than you were maybe looking for.

Cheers.


(....like what DannoXYZ said above)

Speak with Slvoid. His setup is BRIGHT! He has HIDs though. I still can't belive that little light of his can produce so much damn light.

For an LED, the L&M Vega does pretty good.

ok, this completely tangential, but the thread title made me think of it. Did anyone happen to catch the sylvannia headlight bulb add during the Houston Jacksonville game saturday? the shot is of a texans cheerleader's two best assets, the sylvannia graphic is in front of her, and the narration is, don't you want the best headlights you can get?

There are some great people doing Mod's that are super bright in the led market.. One that will be sold soon is the Elektrolumens Quadstar.. This is one bright light and have bought some other items from this guy and the quality is superb.. Beamshots are below..

Now we're talking! A quad Luxeon starts making LEDs competitive with halogens for light-output. At 12-14w, we have a lifespan of about 2-hours for 6 C-cells. Slightly longer than one hour commute per day, about 6-8-hours total per week and we're looking at 24 C-cells per week!

I wonder what the non-rechargable requirement was all about?

I'd like to see some beam comparisons between those modded LEDs and the current crop of bright HIDs

You can use nimh rechargeables.. He is considering getting a RC style rechargeable battery.. That would boost runtime to 4 hours..

NO.

Especially at speed, in the rain, and as you mentioned against car headlights, or all three at once. Not happening.

If you need both bottle cages get a Two Fish strap on bottle cage and put the battery in that and strap it to the top tube. Get a light with a Li-Ion battery, they are the lightest.
The non rechargeable lights are too costly if you ride at night on any kind of a regular basis anyway. The batteries cost way too much. Carry the battery during the day, at night you'll be glad you did. There's no good way around it anyway.

The "Light selection guide" and the high mileage night riders will agree with this. Read the first post in the” Light selection guide" and look at the nighttime beam comparison photos that the links take you too. This will allow you to see for yourself.

I just built a HID light out of parts bought at Batteryspace.com (didn't take a whole lot of building though as they supplied a kit). I made the jump from two Cateye EL-500s to this and it is a beautiful thiing. Anyway, it is pretty bright. First time I have actually not had to alter my speed for night riding.

The 20w halogen with the Li Ion battery they sell is only $100. You can't beat that!

How much did you spend total?
