What brand is the one you bought from e-bay? I use Hortilux bulbs and they burn pretty yellow. You may have had a standard bulb to start with hence the white color.

Whats up Fiction. I know the 400 watt HPS we have burns a yellow orange color. IMO you got the right bulb.

"Most" standard HPS lamps burn with a more yellow(red) spectrum. Though I do think that brands will differ slightly. Possibly the one you have been useing is a "conversion" bulb???..they burn much 'bluer'/whiter than a standard HPS.

The brand of the i purchased on ebay is unknown. Theirs no labels on it or anything, The name of the company I bought it from is called "inside sun". The light I've been using is a 400watt hps from diamond horticulture. They both seem to be working though. I was just curious to see why one burns white and the other orange. Thanks for the feedback Biffdog!

As far as I know inside sun has good stuff, I know they come highly recomended by Mutt. If I had to guess I would say you had a regular bulb (not specific for plant use) originally and now you have a better one.
No problem man, keep on keepin' on.
