My MTE P7s and luxeon K2 setup
 

Beam pattern works great for me.
for about 90 dollars I bought the lamps and associated accesories, batteries, mounts, chargers.

they had flickering but with help form this forum and the writeups at candlepowerforums, they work well now.

all shot at 28mm, full frame, iso200 3 sec. exposure at f/4.0 and processed from raw with lightroom3 defaults, which includes some NR and black point curves but nothing else. auto wb.

2 p7 lamps, 2 luxeon k2 red lamps. one p7 is 'light painting' the foreground.

bar light is 5-mode, helmet is 2.

normally i'll run the bar on strobe, the helmet on low or not at all, a random blinkie on my bag, and the tails only in situations where i want to actively keep people off my tail.

Setup
 

Nice setup. Would you mind providing links to the lights you're using? Also, you mention some fixes you had to do ... what were those?

Thanks!

apparently MTE was trademarked by some guy, and deal extreme just used his brand because they made his products and decided they could use his name on different, cheaper lamps. the 5mode i have is called 'sf-15' and was only sold through dx, and the other one is longer and wider and is a 2 mode, but had the same problems.

i had to sand down the contact points on the open-type tail caps to provide an adequate connection of the switch to the body.

both skus were retired. i think they probably just replaced them with better, more expensive lights. i can't say which ones that are currently available would be good now, but i would assume the better the reviews the better the light.

i'd really like to DIY these a little further so the mounts are a little less in the way. don't think i'd go so far as to make an external housing though.
