I have them under a grow-lux bulb.
Just a caution to everyone who is starting seedlings under grow lights. The electric companies monitor electric usage and the DEA monitors that. If you have a huge increase over last year they MAY come to your home to see if you are growing pot. That is one of the ways they catch the indoor pot growers.
REMEMBER, they don't need a warrant for this, the increased electric usage is PROBABLE CAUSE, and they can and have entered homes to look for illegal drugs.

OMG! i can see it now . . . lol!~

i was planning on getting those bulbs for my kitchen garden. between that and the new freezer, i may end up a *red flag*! after their investigation, i wonder if they'll put me on an extremist watch list?!

Maybe this explains some of the odd that have happened to me!

I have had a big 4-foot long, 3-tier setup of fluorescent grow lights in my family room for a long time. I have used it for everything from tomato seedlings to herbs to African violets to annuals for my garden. I did not use it the last few years, but was thinking of starting up again if I expanded my garden in the spring. Of course anyone can see right into the room when the curtains are open.
I'll be right there on "the list" with you, straybaby, lesliek, and Suelovescats! BTW, you need an awful lot of light power to get tomato plants to blossom under lights. Most setups just won't do it. You would also have to hand-pollinate them to get actual tomatoes.
