ok, thanks...
i had a core/coil ballast and one of the huge globe bulbs and was having problems with an even light and such, i just got an electronic ballast for cheap and ordered a ushio bulb, so i'm going to work on a newer nicer enclosure with this new setup |

Are you sure a reflector's needed? I mean, I've heard most reflectors only add about 30% more brightness. I've also heard the ushio is plenty bright without. But for all I know, you're right. Just asking. |

| so far no matter what bulb yer useing you can always use more light .... so 30% is alot |
|
|
| skullkeeper |
| 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. |

| thanks for the replies guys, now....what's the best reflector for a ushio light? and something i can either get locally here in louisiana or order for fairly cheap |
|
|
| skullkeeper |

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. |
|
|
| eight_heads |
| have you used one of these? |
|
|
| hailrazer |
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. |

| ok, thanks, i will probuably order one..... actually i'm using fresnals from my ohp and the distance of the light source to the fresnals in the ohp are 330mm, will there reflector still work because they are saying it's for a 220mm |
|
|
| hailrazer |
| Yes it will still work. |

| how close to the ushio should i place the reflector? also what are you guys using to hold it in place, it meaning the reflector. thanks in advance for any assistance |
|
|
| hailrazer |
It should almost touch the outer glass on the Ushio.
Here's how I did mine. 
 |
|
|

| well like with any parabolic reflector, if the reflector made a complete sphere, the center of the light source should be in the center of the sphere |
