MegaSack DRAW - 6pm Christmas Eve - LIVE on our YouTube Channel
Hi,
I have read through the main thread on this topic and realise that developments are continually moving on, so could still do with some advice please.
I have two sets of halogen lumi's to convert, 13.2v 4 a/hr NiMH batteries.
Is the output of one can converted = to or better than a pair 20/12 halogens?
Burn time would be reasonably longer?
Triple or Quad XPG kit from Cutters ( http://www.cutter.com.au/proddetail.php?prod=cut756), is this the way to go and all I need?
Any other suggestions?
Cheers

I see you also posted on the 8 page led Lumi conversion thread.
Have u read through the whole thing? I recently converted a pair of light and learnt a load from that thread...
I used:
Cutter XPG LEDs
Cutter optics
Driver from BlackCatTech on Ebay
200k resistor to allow low/high power
3way switch from Maplin for high/low off
Home made heatsink for the LED board
Heatshrink
Thermal transfer paste
There are other ways to do it using different drivers and stuff but the blackcat one is very compact so works well. You definitely need a heatsink to get the heat from the LEDs to the can.
I would say that one xpg conversion is almost as bright as the 20w halogen. That is with a 660ma driver.
I run tested them a few weeks ago and 2 cans on full lasted 7hrs 20mins with the large 'endurance' Lumi battery.
