Great deal on MH bulbs

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.
