Pros: use very little electricity
Cons: give spot light, but not flood light - very expensive
I bit the bullet and bought this LED for my art table, because I have it on all day. The bulb cost a FORTUNE, but I was doing it to save on electricity, and not get compact fluorescent bulbs - because they have mercury in them. (I know they don't have a lot - but there are million of people who are now buying them, and NOT disposing of them properly - so we exchange one problem for another!).
Anyway, this bulb doesn't give me enough light to do my artwork, and I ended up having to get a full spectrum fluorescent bulb anyway - but I know how to dispose of it! Just don't be around it if it breaks!
