Well... now I have:
Front:
* 1 X Red ringed ebay light.
* 1 X Silver ringed 'deal extreme' light (Almost the same as the ebay, but slightly worse build quality and missing rubber seal).
* 2 X Gold ringed ebay lights.
Rear:
* 2 X rear ebay lights that came with the ebay lights. Actually very good but don't include a waterseal, so would need something sorting for that... some thick grease perhaps or silicone.
I should also have at some point the 5 led front light coming which I will use purely as a flashing unit for it's 150 hours operation (I hope), and that also comes with the same rear light as the 5W Cree ebay one's , and I will be donating it to a friend who lent me a light.
Additional parts I have:
1 X 4xAA serial battery box
4 X Sanyo Eneloop's. (Excellent batteries and work with my Panasonic quick charger
)
The expensive 1000ma constant current LED driver (£10!).
Lots of random wiring and connectors.
Basically.. I will probably trying to re-modify my existing Red Ebay XR-E R2 LED unit and put in the constant current driver, and also try and modify the Silver light to be used with the 4xAA battery pack. I have at my disposal 2 old ebay LEDS that I can burn out so I'm not currently worried about overvolting it. I may also try to shorten the length of the light so it's lighter for helmet mounting, although this will of course mean slightly worse heat dissapation :-(
