One more datum for this "survey":
I bought one 60w equivalent LED bulb for replacement in my ceiling
fixture in the room which serves as my ham shack. That places it
about 5-feet from my radios. I bought it from Home Depot and is a
CREE LED listing 800 lumens at 5000K and uses 9w. It has the
built-in base PS and screws into a standard light fixture. CREE
lists life for 22.8 years at 3-hour/day usage and has limited
warranty for ten years. Cost $11.98
I am seeing NO RFI from it on HF to mw frequencies. I will start
replacing several of our cheap GE incandescent bulbs with the CREE;
average life for the 50cent GE's is 30-days. Break even is 24-months
on cost without taking into consideration energy savings.
