I used one for the first time last week and noticed that the output seemed dim so I tried another one. It- and several others were all the same-- putting out about 40 watts (measured with a light meter).
I took them back to the merchant and complained that they are mismarked but since I didn't have my receipt, he would only give me the lowest clearance price- $2.00- which wasn't worth it.
I really have no use for 40 watt bulbs and short of letting the kids use them as targets, I don't know what to do with them. Any ideas?
