suplementary light?? what do ya think of these...

just spotted these on an electrical store site, and had a look on ebay..
Thought they could be of use to people with limited budgets doin cfl grows to get some extra lighting to the sides or at the canopy..

just wondered what the experts on here thought?!

It's just a 21W CFL encased in a housing. You'd get more for your money buying a 42W CFL and putting it in a normal desk lamp.
