[R-390] LED lamp replacement

[Bob Camp]

Hi

There are also a couple of other alternatives. The ones you list are by 
far the most common. I have always gotten mine from Bulbs Direct on the 
net. Never thought to check Mouser for them.

If anybody is looking for the even longer life but far more dim (= not 
a lot of use ...) alternatives I can probably dig out my notes.

	Thanks!
