best battery bike light image
Sdfaad
So I wanted to make a bike light so i bought a halogen bulb the rquires 12v 50 watt power. I put some batteries in series to make 12volts but when i connect the bulb it does nothing. why doesnt it do anything>? I even stepped up the volts to 18 with two 9 volt batteries but still nothing. Any ideas?
Answer
50 watts is a lot of power for most batteries. It is likely that your batteries have too much internal resistance and cannot deliver the amount of current required.
To determine this, connect a voltmeter across the light when you connect it the batteries. You will probably see that the voltage drops to much less than 12 volts.

i'm looking to get some proper big lights for my mountain bike (a felt q620). As i'll be going off road a lot i need some lights that will illuminate quite a distance so i put it to you, what is the most powerful bike light i can buy? some links would be greatly appreciated and money isn't an issue (unless its like £2million each :P)

Definitely spend the money on an H.I.D. or one of the super bright new generation LED systems. Don't waste money on a halogen light unless you'll be riding at slower speeds on relatively smooth trails that you know well. Halogen just isn't bright enough for fast riding on trails....you'll out-pace the beam and although it makes for a more exciting ride you can really pay the price in blood that way. :o) Even the dual-light 32w-ish halogen systems aren't bright enough for fast riding in my experience.
When shopping, pay attention to lumens output....that's the best way to compare lights. They're all screwy with their marketing because they know people will want to have the brightest light, so there are all kinds of brightness descriptions out there. And watch for the Best "in its class" claims, too. As said above, run time might really matter to you also....you always need to have a secondary backup light with you just in case (even a flashlight will do) but try to pick a light that will last long enough for your rides and keep in mind that batteries will run for shorter periods as they age or when it's really cold outside. If you plan on doing any 24hr races then you'll want a fast charger, too (and possibly an extra battery for an outrageous price).
I have a Light N Motion HID that is fantastic.....I normally ride with it on my helmet. If you plan on doing any jumps or have really rough trails, you'll probably want to use a bright light on your helmet and some other light on your handlebars so that you won't be landing in complete darkness if you take to the air. Otherwise one light is usually enough. For years I used a Niterider 15w halogen and enjoyed it on the road bike, occasionally on the trail....but it was tricky to make fast turns in the trees and tended to wash out the terrain textures in the red dirt we have around here. The HID is way better so long as you don't blind the raccoons or your riding buddies.
I really like Light N Motion much better than Niterider, but in the last couple years Niterider has finally improved their lights and addressed problems. They're both good companies but my money is with the first one. I hear great things about Dianotte, too, but nobody around here has one that I've seen and I have zero experience with them.
Plan on spending $300 and up. Nashbar, Pricepoint, and Jenson often have some super closeout deals on HID lights from Niterider and Light N Motion. I got mine from Nashbar for about $220 with a sale price and a discount coupon...sweet deal.
EDIT: If you really want a SUPER powerful light....a local guy rigged up his bike with two R/C airplane landing lights and a *heavy* 6v gel battery. Crap, that setup was brighter than highbeams on most cars! A bit overkill, though. lol
