A lady friend of mine owns the local bowling alley. She decided to replace
the fluorescent lights over the alleys with direct wire 4 foot LEDs. When
2/3 done and waiting for more bulbs she reported her electric bill went down
by $200.00 in the first month. The light inside is better than ever. She
figures on saving $300.00 per month when finished with the installation.
$3600 per year is a lot of scratch to save let alone the power saved. I am
thinking the heating bill will go up in the winter however. Here in the NW
natural gas heating is less expensive than electric heating. We will see how
this plays out. This has caused me to order some LEDs for my shop and
laboratory. I will report when they get here how much RFI I can measure from
them. At present I have Lights of America fixtures with F40 bulbs and I have
to turn them off when making low level signal measurements on the bench as
they are so bad with RFI from the BC band clear up to above 50 MHz.

I was at a convenience store/gas station a few weeks ago in the bathroom and
looked up and saw those LED T8 replacements. First i had seen. You
could see the individual LED's in them. I too have some of those
noisy variable voltage input ballasts in my shop. Interested thread.
