skullkeeper · 2nd February 2006, 01:52 AM

you have read right but if you dont use a reflector for the extra 30% of light why buy a 400 w if your not going to use all its light seems pointless to me.

The best reflector for the Ushio is the new Pro Reflector from LumenLabs..

It's $15 and adds about 25% more brightness than a Norpro or Ikea reflector.

have you used one of these?

hailrazer · 2nd February 2006, 02:59 PM

Yes I'm using it right now.

I had the Ikea reflector first. With the Pro Reflector the increase in brightness was very noticeable and the light was more uniform on the screen also. Stainless steel reflectors seem to make "hot spots" and the Pro Reflector evens the light out better while increasing brightness a lot.
