Rated 4 out of 5 by CheGuevarra1 Average Replacement Ballast
This ballast really gets noisy on a very hot day even though I have it in an air cooled ballast box with axial fan. The ignitor is weak and doesn't light my [blank] brand pulse start 4k lamp to the 44,000 lumens that it should according to my light meter. I switched the lamp over to another brand and it was accurate dead on with lumen intensity. Also , the ballast to lamp distance in the pdf download states 105 feet. I think there may be a mix up because this can't be true. If it is true then I guess the pf is lower than stated.

I used these ballasts to replace existing ballasts that were not working. They were very easy to install and they worked perfectly.
