Don't know if it's been covered before but thought I'd share this with you. I've been looking for some big lights recently, Hope Vision, Exposure, Lupine Betty etc. All great stuff but looking at say 300 GBP I hesitated. Then I found this review advocating SSC P7 LED flashlights as suitable for riding: http://www.mtbbritain.co.uk/mountain_bike_lights_review_led.html
My non-educated guess this is China manufactured LED emitters for the automotive market and battery tech from laptop PC's. With the flashlight market being much bigger than the bike-light market it all adds up. I got a 900 Lumen torch, 2 Li-ion batteries, a charger, helmet and handlebar mounts including shipping to Holland for 80 $US! (62 EUR).
It weighs in at about 200 grams with battery and lasts 60-80 minutes at Max setting on a full charge, 2 hours on Medium. It's an all aluminium housing sealed with an O-ring, the threaded cap feels well made too. Battery change is a 1 minute doddle, and the extra battery weighs 50gr.
I've opted for a newer, slightly larger and more powerful MTE model than the article. It features a metal reflector, a wider beam pattern for trail riding and some extra settings (Lo-Mid-Hi). Don't know if they make the claimed 900 lumens, but frankly I don't care. I reckon even in Mid setting it's good enough for riding, very bright indeed.
Note: the links to the HongKong supplier do not work at time of posting, sorry, they were fine earlier today. I hope it's just something like server maintenance. I will post updates here how it's holding up, but if it survives the first few rides I'm ordering a second one for a different beam pattern and back-up.
Edit: I just saw that I posted this in retro chat,
Apologies, I had intended to post it in off-topic.
