These from lidl are quite bright and last a good while too £3.99.....
But my mate works in a outdoor clothing and workwear place..and they have bought all the Princeton Corona head torches off their suppliers and got them today so that they can sell them at £35 usual price £55 i think
Now i don't really like headtorches with a seperate battery pack...had so much trouble with loads of Petzl ones but the guys say these are a lot better made
just find a way of hanging them in the tent when there not on your head
Undoubtedly in a class by itself, the new Corona Headlamp is the brightest and most efficient area light on the market.
Eight super bright white, shock resistant, virtually unbreakable wide angle LED’s are the foundation of the Corona, allowing the user to switch between 8, 5, 3 or 1 LED use - making it a great hands free lighting choice to satisfy all of your outdoor, work and personal lighting needs.
The multiple modes and functions allow this headlamp to perform every task needed around camp and trail, from flooding your entire camp site in bright light or powering down for more up close tasks, like reading in your tent.
An innovative circuit system allows the user to fine-tune and adjust to the desired brightness level on each of the 4 LED output modes, while offering maximum constant light output for the life of the installed batteries. The result: a very bright flood/area light that offers excellent peripheral light, allowing the eyes to work with ease in a localized area– there are no dark spots in the user’s vision, neither forward nor side to side.
For the perfect fit, a durable nylon head strap provides plenty of adjustment, and the head assembly pivots to allow you to shine light where you need it. Top it off with 10,000 hours of bulb life, emergency / flashing signal modes

now how many do you want me to get off him?
) off a 3A powersupply. Probably equates to about 0.3A per tube ( it'll say on the packet), allowing approx 15hours use of a single tube before the battery reaches 75% capacity, which should still be plenty to start the bike in the morning
