You can get really really bright proper bike lights, but be prepared to spend a pretty penny! Wiggle have 20% off orders over £100 until end of August, merlin and chainreaction have 10% off - worth a look.

If you're on a real tight budget ledshoppe (for example these are £6 delivered each) is definately worth a look for LED based stuff. Or better still look for bike lights based on Luxeon LEDs.

Most cheaper lights are LED based - I have a Cateye EL520 which is pretty good but I'm guessing you want a lot brighter (I wouldn't ride trails at night on my light!). Cateye EL610 (about £60) is probably the brightest you'll get from a single LED light using regular batteries, but there are plenty of LED-based lights ranging up to several hundred £ that use dedicated Ni-Mh or Li-Ion batteries that are substantially brighter. Luxeon based lights cost a pretty penny (the Blackburn System X6 is £125 delivered at Merlin which seems a really good deal) but offer more light per watt than halogen, thus they can be brighter, run longer and cooler and have lighter batteries, and also come in a much smaller package. Perhaps even better than Luxeon are HID (high-intensity discharge) lamps which seem to cost £150+ (10W is typical output and is rated as 50W equivalent in halogen to give you an idea of intensity).

You can get Ni-Mh based halogen examples like this from chainreaction for under £35 or this one for around £55. Reckon these are your best bet if weight, bulk and runtime are not your key concerns (but cost and power are). NB I haven't checked that these are the best prices around but chainreaction are generally pretty cheap and have good user reviews of the things they sell on their website which is a good feature...

The problem with things like halogen torches designed for car battery use is the power draw - whilst 30 mins might not sound long, if the bulb is 60W (typical for those sorts of devices) you'll need a 2.5Ah 12V (realistically you'ld need SLA (sealed lead-acid) batteries so thats a bulky 3pound battery). And then there is the heat - 60W is quite a bit of heat to dissipate on your handlebars etc (I'm assuming this is for cycling?). The added weight + heat + restriction of mobility + likelyhood of injury in a crash would rule it out for me.

Look on eBay. My friend bought some which Halfords sell for £20 cheaper, down a dark ally on bikes it'd be like day light, clear white bulb'd LEDs.

I have these, http://www.chainreactioncycles.com/Models.aspx?ModelID=9051. Pretty good, front light is amazingly bright.

Hope it helps,

jah128, thankyou so much for your advice, your links have been really helpful. I have decided to save for a really decent light and in the meantime try an LED.

This one from LEDshoppe appears to be very similar to this one jamesterror has.

Thanks again to you both for the assistance.

That LEDshoppe one looks a bargain to me, I'd get a couple to give you some directionality but it should work out about £5 delivered for both! I like LEDshoppe, the stuff is shipped from HK (I think) so takes about a week but you can't knock the prices (generally much better than ebay with the free delivery) - the 3 laser pens for $3 are class if you like that sort of thing.

Long term though, save up for a decent Ni-Mh halogen dual-lamp set at least (I'm doing the same now ready for winter...).

EDIT - By the way, its probably worth also getting some of the spare batteries they sell if you get the $5 LED lights as it uses CR-2032 lithium cells. The 10 packs on LEDshoppe for $5 is probably the cheapest you will find these anyway!

Might buy those LEDshoppe lights, I'm forever getting pissed off with people pulling out thinking i'm going slow, Was almost made part of someones bonnet last week when some guy decides to wait till i'm about 2 metres away to pull out, Didn't even look left or right, Tool!

Get yourself a set of Metal Halide HID lights, like the ones halfway down this page:

http://www.bikepedlar.co.uk/acatalog/Rechargeable_Lights.html

Equivalent to 40W halogen....mmmm....

That way you'll probably blind the driver before he runs into you!

The price of the light over the price of my bike......
