I am currently modifying an Inoled light. For those who do not know, the inoled light is a bike light which uses a 2w cree emitter (unsure of the exact model) and a cleverly designed reflector which focuses the light into a rectangular beam which when projected onto a wall appears brighter at the top thus it lights up the road better and has a fairly distinct cut-off at the top. I somehow got into my head that the Inoled light would accept upto 18v so I hooked it upto a 14.8v battery and after about 5 mins it died, I then read the instructions which said max voltage 14v, oops, oh well gave me a good excuse to take the thing apart, take out the guts and figure out a way of making it brighter.
I decided to replace the LED with a SSC P7. The only driver I currently have is a 1400ma Konlux so I have used that for now. I have a 2800ma Konlux driver on order from Germany but it has not arrived yet. I have used a P4 heatsink for now but have a larger heatsink on order. I will be cutting a hole in the bottom of the housing for the larger heatsink for more effective cooling.
I have made a PWM dimmer with a 555, a pot, NPN transistor and a few other bits.
Here are beam shots
P7 Inoled at 1400ma (about 400 lumen)
My existing bike light, a lumicycle HID which is about 700 lumens.
The garden fence is about 90 feet away
If I can get hold of one, I will post a shot of an unmodified inoled.
I will post beam shots of the P7 at full power when I get the new driver although I may have to limit the max power with the driver to prevent the plastic reflector and housing from melting. After running it at about 1400ma on a P4 heatsink for about 30 mins the heatsink was warm to the touch but nowhere near melting temp and I could still comfortably touch it.
