Great deal on MH bulbs

Pescador · #1 08-08-2006, 09:01 PM

Just got my bulbs, 2x250 10k DE and 150 20k DE each one in a seperate package. I paid 10$ each shipping but each one is in it's own tupperware container with bubblewrap. They came from Hong Kong and no duty was owing. (Gifts)
I haven't fired them up so I can't compare the color yet.

My 175DE 14k just arrived - fired up nicely on my 150de ballast (was 99% sure it would). Nice color, bit yellow for a 14k but no complaints for an 12$ bulb.

So I retract my previous statement about him, must have been the language barrier...

I'll bet its yellowish because its not running at the wattage its rated for.

Could be 14% under wattage, but there are plenty of ballasts that put out well under or well over what they are rated at. Thats why the same bulb can look very different under differing ballasts (even of the same make/model).

Not a 14% variance though.. usually the tolerance on a ballast is small, I would have to look it up to be sure but I am thinking +/- 5watts if that. anyways the way you are running is indicating that it is totally messed up as you are getting yellow out of a 14K bulb which should be blue... period. I would try it on a proper ballast so you can see the difference.
