20K Metal Halides

Thomalop · 06/13/2008, 05:24 PM

I just bought some 20K metal halides.

Does it take a little time for the deep blue to kick in?

What type are they?

Mine ( XMs, 250 SE ) actually got brighter after they burned in, and I am very pleased with the color now.

They are 400 watts.

It is very bright. No blue hue at all.

LPS told me that there is a "burn in" period before the blue hue really settles in.

Is this true?

There is usually a burn in period of a day or two before the true color comes in, but it really depends on what brand they are. Some brands of 14Ks are more blue than 20ks of other brands.

LFS said that it could take up to 2 weeks depending on tehe ballast and brand of lights.

I hope this is true.

Two weeks is not true what brand are they ? I rarely trust the advice of people who are trying to make money off of me!

I bought them off of e-bay.

They are stamped with 20k but my 14k bulbs run bluer.

E-bay might be the problem. Bought them from great del. I have seen some positive remarks on them in the lighting forum.

I was just wondering if they got bluer over time cause if not i'm going to get some other bulbs.

not sure with the e-bay brand bulbs but my XM 20K's actually got more brighter (whiteish) after they burned in just like Todd's and I run the 400's
