Product review (5 stars): Good price for long lasting incandescent grow bulbs
Identical product number as the last set of these bulbs I purchased, but the blue paint is a much lighter shade of blue than on the previous bulbs.  Once they are lit, the light produced looks the same to me.  The old ones lasted reasonably well, considering they are on for 12+ hours every day, so I hope the new ones are the same quality.
