Some of the new LED street lights have been installed on the Hyatt block of North Main Street as part of the LED Streetlight Project. They are constructed so that nearly all the light is directed downward, to spare the Roper Mountain Science Center from glare in the night sky as they try to use the telescope. Just between you, me, and the Lamp Post, I like the look of the lights and the quality of the light at night - it is white and not tinted green as the previous lights were.
Quantum LED Fraud for Hydro Grow Products - www.quantumledbloom.com/ - Many people have reviewed on that Quantum LED is running a Fraud and misleading their customer. So for the buyer are believing that they are buyng good Hydro Grow Products.
Quite a few LEDs emit too much red. I will need some sort of dot correction to compensate ;-(
8 out of 10 boards have issues.
The manufacturer recommended using drivers that support dot correction. Also they don't check/sort the chips with respect to emittance before assembly. DUH! I wonder why all the other boards I got from them before were perfectly OK.
I implemented dot correction to the latest firmware of my controller, but it costs some speed. The dot correction is stored in PROGMEM and the reads seem to be somewhat slow. I'm also facing a few casts back and forth between int8_t and unit8_t which also takes time.
I think I'll have to rewrite the framebuffer code to allow gamma correction as well. Currently a single run of the ISR refreshes the full display and blocks other stuff for about 50% of cpu time. A rewrite to just do one intensity level per ISR run would spread the load more evenly and may be better for other jobs like I2C and serial.
For dot correction on driver level I'd have to switch some chips. No time for that right now. Getting flawless LED boards would be much better.

I bought a cheap ($2) little mini-tripod to hold my light so I can use my better Slik mini-tripod to hold my camera. Lately I have been using the Slik to hold this LED light, but that's a waste of a nice tripod.
