I have an MH bulb labled BT28 that i was going to run in my veg closet but it burns with a red glow like a 2700k CFL..shouldn't it burn with a blue/white glow like a 6500k if I'm using it for veg?

If you have doubts about a bulb. Please don't run it. Is the bulb blackened or anything?Pics will get you a good response from the right people.

Can you return it?

Nope. I came up on a 400w ballast and housing that was designed for outdoor applications like parking lots for dirt cheap at an auction. This bulb was already in it..
 
You think its still ok to veg under?? I appreciate your input.
If its what you have yes, it will veg and flower plants. 3500-4000 is right about in the middle where you would want to be if you planned to use this bulb throughout the grow for veg & flower. I vegged and flowered my entire last run under 3500K CXB3070's
