Metal Halide Lighting Bulb Replacement?
I have a metal halide lamp and one bulb is burned out. The numbers on the old bulb are: 2 P 320 ex 39hc / 320w mh m 154 v
If anyone can point me to a website where I can buy one or two of these (read not in bulk) that would be greatly appreciated.
Although ignorant on my part, I'm not looking for a lengthy message about why this lamp is better or that lamp is better, nor am I looking for an explanation of what each number/letter means.
I do not know what ballast or anything else about this light, only the bulb size, so I need to replace in kind.
Thanks,

Lowes or HD won't have the 320''s.
If the bulb is about 3.5" across at the fat part of the lamp then you want this lamp http://www.amazon.com/gp/product/B000TZR3VA/ref=as...
If the lamp is 4.5"+ then you need http://www.amazon.com/gp/product/B001JEPKJ2/ref=as... , you can use the cheaper and smaller lamp above, but the light reflection pattern for smaller lamp may be uneven if fixture was built for the larger lamp.
The key in the whole description is "m154". That is an ansi spec that defines the ballast starting and operating characteristics.
They would sell more if they made a 420w bulb!
