Not too sure - have to contact my mate and find out. they look like a vesion of the low energy flourescents that you can fix to standard ceiling light fittings. Look pretty neat, light is good (they take a few minutes to warm up as do the other flourescents) and they have the added advantage of being low energy, Our kitchen has 6 x 50W halogens, that's 300W when they're all going. So they should help with energy saving, mind you they did look at bit on the €€€ side.
