A few parts for the 500w GS3 conversion including a fiat punto radiator.  May take some time,  will post pics as it goes

This is one of the golden scan 2's.  Now 300w led.  As it's so cool I may upgrade to 4-500w,  a well designed heatsink will fit in there and still be way cooler than halide.  A lux meter is on the way...

I may remove the collimator lens to see if more light can be concentrated through the gate

Base temp after 15 minuites.  Well below what I expected.  If I can get a 500w chip with 3-400 thermal watts dissipation down to that temp I will be well pleased.  Full 100,000 hours minimum which is the aim.  Pro light (apparent 1200 hid replacement) puts out 4000 lumens (not lux) at 5m/15 degrees so if I can equal that I'll be happy.  Especially without using water cooling.  Although secretly I would expect to thrash that, even with ordinary glass lenses

Nice ! good to see people still care for (in my opinion) THE fixture which defined lighting for the rave scene (the strobeflowe comes to mind but never really took off over here at the mainland). is this purely a "because I can" idea or are you converting an complete shed of goldenscans? now older fixtures are so cheap it seems like the first option.

How sharp are your gobos? Bright is one thing, even beam and crisp gobos are another...

Yes,  but thats done by the front focus lens and even beam is a problem for smaller point source hid bulbs,  larger sources have the opposite problem however far easier to deal with..

I suppose it's because I can,  I refuse to pay hard earned money for a 2000hr bulb!  Especially when times wasted making up chases etc.  

Theres not quite a shedload,  just 4 gs2's and a HPE.  I'll add more pics when the hpe 500w is done

Finding large cob heatsinks for less than $250 is quite difficult pluss they wont fit the enclosures.  This is 6mm plate and server coolers,  theres two more 150mm ones for the other side (with the led on).  I may also replace the outer case fans for lighter 12v ones the cast ac ones are heavy

Pro lights 'luma' uses water cooling.  I did consider but it's about the same price and I don't trust water being around.  Also if the internal pump goes you cannot see it

..if the internal fans stop at least the draw from the external ones is enough to prevent faliure.  I suppose with moving heads weight is a factor..

It's taken nearly a year and a half to get this far?
