Led light replacement of a 300wat halogen

Sorry to continue the hijack. I just ordered two LED bulbs from the far east as possible replacements for CFL type bulbs since, as BillO pointed out, they don't last long, especially when installed base up. They are in the 10W/1000 lumen range and intended to replace the typical 18W CFL. One is a corn-cob type (~$6) the other is a globe type (~$10). If they work out (and that is by no means a foregone conclusion) they would be worth the cost. We'll have to see.
