Wanting Residential LED Downlighting, Made-In-USA

 Google this: What manufacturer is doing innovation in Made-In-USA "residential" LED downlighting?

Learn that there is no Residential LED lights manufacturing in USA. Until recently there was Ilumigreen in Michigan. This is bad news.

Ilumigreen.

I have a half-dozen in my museum collection.

Lights from American Lighting seem to be interesting.

I have made my phone call to Customer Service and find that these lights are not made in USA. Somewhere in Asia.  They mount to junction boxes with screws through the board backplate with keyways that do admit bug littering of the lens. If screws passed through round holes, that would be a very big product improvement. I will persist in now trying to buy a sample via Amazon, as instructed. I won't bother to buy, but wonder whether any old lights-buyer-from-Asia, has a market via Amazon. And, the answer is Yes! Bad news for Amazon.

Luminance if 4" lens: 650/8107 = 0.080 Lumens per sq millimeter. TOO MUCH GLARE. Probably made worse vs. edge lights by concentrated diodes not obscured by the thin lens.

(Please see the table that follows.)

Luminance if 6" lens: 1050/12350 = 0.085 Lumens per sq millimeter. TOO MUCH GLARE. Probably made worse vs. edge lights by concentrated diodes not obscured by the thin lens.

Luminance if 5" lens: 750/12688 = 0.059 Lumens per sq millimeter. Maybe OK. This is better glare than similar-appearance HALO SMX and without some HALO silliness. Could I buy and try this, via Amazon?

$73.46 each

Far too expensive. Not a realistic product-for-sale.

Shipping from store Lighting Jungle, in Las Vegas. Selling tacky old stuff. It seems to have ugly thickness.

Lights are non-glaring if luminance does not exceed 0.05 lumens per square millimeter. 

With edge lights, lens lumens output at fixed diode power increases in proportion to diameter. A buyer might expect lumens output to increase in proportion to lens area, that is, as the square of lens diameter.
