[RFI] LED Tube Lights

[Roger (K8RI)]

I have what I consider a small shop in which I can do computer work, 
repair my ham radio equipment, plus half of an SO2R set up, Welding (arc 
and gas), plasma torch, and machine tools.

My shop has 22 8' 75W Fluorescent tubes for light.  The interior is 
baked on, white enamel on barn metal, so it's well lit. Imagine 
replacing 22 5,000 lumen tubes with  LEDs producing a combined output of 
110,000 lumens.  It'd cost a small fortune.

I replaced all interior lights in the house with CFLs which worked well. 
Most of those have been replaced with LED equivalents of the old 
incandescents.  They are instant on at full brilliance including the 
garage lights where it gets COLD! even if they were a bit pricey.  
They'll probably last longer than I do and with less mainteenance.
