Considering that the UL/CSA was implemented in quite another time, I wonder if it is time to up their game a bit...
Not that I'm particularly thrilled with regulation in general, even if UL/CSA are independent of Government. In essence it appears to me that they are really quasi-governmental?
I'm not sure where the "FCC" mark comes from as far as where the jurisdiction of one leaves off and the other starts:
I suspect that It MIGHT be BOTH in that UL/CSA looks at a device JUST from a point of fire, and FCC looks at that SAME device just as an emitter/receiver, hence you get the UL/CSA and FCC marks.
My guess is that the FCC/CTRC (and maybe Industry Canada) regulates RF emitters and receivers just for these qualities ONLY.
You see that FCC statement that says something like:
"This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation."
But today, just about everything is a receiver, intended or not(!) so maybe something needs changed in reference to (2)?
We can't have washers or heating systems running amok. Or self driving cars!
As far as the LED Bulbs go it seems that one just has to try them out, and interference seems not to have much rhyme or reason as to price or brand.
A bit off topic now, but I have six of those 5000 Lumen (and 5000K) WalMart "Hypertough" LED shop lights here in the shack, and was worried about them causing RFI. So I brought ONE home, put it up, NO problems at all. Then I purchased the rest, and installed each one individually to rule out and isolate any potential manufacturing defects with any single one.
While I DO turn them on and off with an inline switch right at the mains sockets, to save the wear, tear and hassle of using the pull chains as I have found in the past that these are usually the "Weak Point" in all shop lights in general...I am happy to report and HIGHLY recommend these lights. Gosh, they just really work well and I prefer the 5000K temperature as they don't annoyingly "change" the colours of things like Resistor ID bands.
They seem to be as close as you can get to "regular natural light" in my retinas opinion.
We don't all see the same, and my Wife and Daughters prefer the 2700K lights... I suppose that their retinas/brains are different and the colours "pop" better for them at this range. It definitely does seem to be a Gender thing in my Informal Survey... Interesting!
