You already asked that question and got an answer here … [My first grOW. Unknown strain. :) - #25 by Paranorman](http://ilgmforum.com/t/my-first-grow-unknown-strain/5390/25) What part of HPS light is yellowish is puzzling you? From what I can read on your ballast above it says it runs sodium or halide, why don’t you buy a halide? ---

That ballast actually says mercury or halide. I wonder what type of bulb he put in it. ---

Whoa hold up girl @rjw71 just spotted something! I don’t think that’s a HPS ballast! You need to read the ballast again, maybe that’s why it’s a weird color Good eye rj! ---

Does the bulb have a kelvin color rating on it? ~MacG ---

Unfortunately that doesn’t show the kelvin color of the bulb itself. But it does appear to be the right type of bulb for this fixture/ballast. ~MacG ---

> [@What kind of fluorescents can I use?](http://ilgmforum.com/t/what-kind-of-fluorescents-can-i-use/5338/5): > > I already bought one. The one I already have is a 400w high pressure sodium and the one I ordered on eBay is a 400w metal halide. I’m going to use the metal halide during the veg stage, when it’s time for flowing I’ll switch to hps. I think I have it right. I have done tons an tons of research I’m starting small. Keeping it simple until I learn an get a few grows under my belt. Thank you. For your help. Above is why I thought she had HPS, sloppy reading on my part, sorry Ashley Yes it should be a whitish-blue, you’re right Ashley. I don’t know why it’s yellow like a sodium look on the bub maybe it’s the wrong bulb? ---

And the color being described and that appears in the photograph does look more like a 2100K color. ~MacG ---

Sounds like the gas in the bulb isn’t burning hot enough. ---

Well, that’s not a halide or mercury vapor bulb, that looks like a h.p.sodium. it’s not a conversion bulb, is it ?
