Yellow MH bulbs
I bought some Ushio bulbs from JL and I noticed that the 10,000K bulbs appear to be more yellow (less blue) than the previous ones I bought. Has anybody else noticed this? Is this the new color of the 10,000K bulbs, or is there something wrong with the ones I have. The new bulbs do not have the silver base like the old ones did.
Somebody told me that it takes about 100 hours to burn in, but I have now been running them for longer than that, and they are still yellowy.

all bulbs have varences, different batches ect. so any one bulb will have slight differences in output and in color. after the burn in it should be better but personaly I think this is more due to you getting used to the color.
are you seeing the yellow while running actinic lighting? Also I expect to see a hint of yellow in a 10K bulb, and more so in a lower K bulb. Steve

I thought it was just my tank!!!
I changed my bulbs in early January....I am sure they have "burned in" by now and are still much yellower than the last set...I am quite unhappy with the current look...
