I'm not getting boards made up with tracks on initially as this is just a test and I don't currently have the facilities. I plan on using a sheet of PCB with holes cut in the same spaces with the non copper side face up as a spacer to give the gap that they currently have. I've cracked them off of the heatsink so i can split that up, once I've found a solid setting adhesive (like the one that is on the heatsink now) I can get this moving on and hard wire them to a flying lead with a 4 pin xlr and a socket sitting in the block where the lens was.


blah blah blah blah blah......

If it sounds like a gorilla is trying to escape, turn it down.

Hi,  sorry for late replies.  I drilled the baseplates through and used m2 bolts and copper grease/aluminium paste.  Alumimium does'nt last that long if you tap it and have to remove them a few times while you work on it.  Lux meter has come so can do some tests soon...

Good to see you all working on stuff keeping old units going

Hi when I get a chance I'll go through it and check around. I remember a guy converted some mini scans years ago very well. He used a home cnc to make a made to measure heatsink. Think it was just 100w chip..
 
I know who you are talking about, Ive jumped on his post over on the BlueRoom Wink feeling a bit more comfortable about this now, though still WAY too many projects that im not making progress on!

I know,  I've sold an old project car to get these out the way...

This is a 200w cold white chip.  The first colours and open white are in low power mode (last forever mode) the last white is full 200w.

Initially I was very dissapointed but after some head scratching I realised that the light meter went x10 / x100 automatically, and it was in x100 mode,  so heres the results
 
Low power
0 distance 7520   Lux
5m  1880   Lux

High power
0 distance  11280 Lux
5m 2820   Lux

The last photo shows the meter in x100 does'nt register ambient light
