Default PC retrofit question

Well I certainly would not put cardboard there. I have added retro PC
lights in the typical plastic strip lights already, and its normally
one of the first things I do, when I get a typical striplight. I
bought some electronic ballasts that handle 24 to 65 watt PC's for
about $20 each and I also got a bunch of ballasts from inside jewelery
display cases that used PC fixtures, and they cam in handy for the
plstic light housings. I did add a decent reflector (LFS had a
closeout on some super reflectors for like $1.00 each that were made
and sold by URI that were hard to pass up, so I mounted the ballasts
remotely of the hood itself, installed a spacer made of PVC between
the reflector and the plastic hood itself, and also the PC bulb
socket. I also added a small 1.5" muffin fan on some and on others I
used 2 of the fans. SInce the lights themselves have a permanently
attached / sealed glass in them, its perfect with fans as it pulls
air into and pushes it down the length of the strip light hood, and
out the other end, ( I used the original ventilation vent for exhaust
vent. I also used 115 volt fans and have them to turn on when the
light comes on. If they did not have a cover glass built into the
lights I would have used a 12 VDC fan instead.
They work fantastic.

plastic fixture?

I was thinking I could put a layer of cardboard between the reflector and
the housing to absorb some of the heat.


Thanks,
