[RFI] LED Bulbs

[Mike Ryan]

Dale, I think PORTFOLIO is Lowes brand.  The other stores may and most 
likely do have the same or similar product but under another name.  -Mike

Noted.  I don't have a Lowes close by, but I do have a Home Depot and 
Menards.  Next time I'm there I will look for this product and perhaps drop 
some suggestions. I do know someone who works in the electrical department 
at Menards, he's a ham operator too.  I'll pass this information along to 
him, minus all the headers etc.

Thanks Mike.
