OK on all, Kim;
The PHILLIPS brand sounds possibly more expensive, is my only thought.
(I have seen off-brand and therefore lower cost units from China...)
In my case, I have six double-lamp units in my shop, and I sense no FRI
from a ballast or the lamps. (In answer to your observation of the
ballasts being a source of RFI noise.)
I had read of the need to re-wire the fixture; In the case of your
Phillips units, this was not needed? If so, this is nice!

I have some Phillips LED tubes as drop in replacements for T8 tubes.
All are quiet. It's the ballasts that are problematic. In my case,
they're quiet, too.

Good day all;
I have been seeing more REPLACEMENT LAMPS for my shop's 4-foot
florescent lamps, with the replacement being of the LED design.
(-Same lumen levels, lots lower power consumption, extremely long
lamp life expectancy are the selling points.)
I have read of several folks that had noise issues with under-counter
LED strings, in which the source of the noise was the DC power supply
for the strings of LEDs.
How are the LED replacements for standard 4-foot florescent lamps, as
for noise or RFI generation? (Any advice?)
Thank you, and 73; -Mike- K0JTA
