Ha if I have time,  I may be back to work soon then they will get shelved again..will see.   If it's just mini's 150w led will suffice.  You can use deep cool cpu coolers for those. 

Do you have a spare one so you can strip one down in the house and still have a set?

Parts of the next scanner.  This one did control the colour wheel a bit funny and I noticed some of the caps are blown.  You cant see well from the photo. I've ordered a bunch 1000uV 25v so will replace them,  see how it goes

60 degree lenses came today.  Though cheap from china I'm impressed with the finish also their meniscus,  concave on the rear which is very good,  will lose less light and give a cleaner focus than plano-convex.  Though that's not what I ordered...

This one has an experimental 200w led so may just use this unit for colour changer,  see how it compares with the 5's or sell it

The nearer section looks shinier,  it was so cold that I had to thin the paint down and it came out glossy.  Still alot better than before.  It was a salvage from a shed.  Although the outside was all rusty the pcb's inside were like new :o)

Hi guys, have to work for a while now but when I get back should have enough parts here to get the 500w fired up.  Also the lux meter will be here,  do some real life photometrics...

I've ordered one of these ::


Its a tir lens big enough for the 500w led.  I'm unsure if it has any aberration in the light bad enough to make gobo problems,  from spec sheets it's apparent there are incident angles but from an efficiency standpoint it's definitely worth a try.  Maybe someone with optic experience will know...

Missed this... I have 6 of them, they dont go out as I have other smaller scanners that currently suffice. For my 'master plan' im working towards I aim to run 4 (having 2 spare) but having them LED will massively help with power consumption. I can find my way around...but at the moment totally in the dark about what I need to progress
