I’m sure that you have all seen the new spiral light bulbs like the ones pictured here. Apparently, Home Depot gave away 1 million of these light bulbs on Sunday for Earth Day. Of course, I did not learn about the promotion until I opened the coupon/circular section of my Sunday newspaper late last night. Anyway, I bought a few at Giant since they are on sale for only $1 instead of the usual price of $4.99. So I’m wondering if anyone has used these bulbs. Are they any good? Do they really save energy?
