Yeah I can see it all unfolding, in advance...

That's not the kind of halo I would want to wear.

Getting my foot operated pedal switch back from Celso. 30 amp rated. Don't want the transformer jumping off the pole in flames or anything...

I see, I see now. (Said the blind man, as he stumbled in the dark) ;)

Yeah, 1995 "La Duena" Actress, Angela Rivera. She had the finest, er, spread in the whole valley. El Premio Mayor (The Grand Prize) The insane antics of Huichol left me hurting for hours. Mexico produces the finest soaps in the world, but I would rather spend my time wondering why the circuit suddenly turned pitch-black and the lights went out.

Beats having men in dark suits show up at my business flashing federal badges and asking why the air force was picking up intense electromagnetic emissions from the yard. That's how I was introduced to DARPA. They flew F-117's and B2 bombers directly over my place. I guess I unintentionally zapped a few of them. Cyclone fence faraday cage and about 1,500 pounds of copper lathe cutting curl scrap fixed that. But then the FCC got into the act. That cost me money.

Homeland Security, NSA, and NASA have been alerted. :B

"I gotta try it.

(4) 33 volt LED chips in series.

(1) 5 amp 1KV rectifier in series for a guarantee

(1) 100uf 450 volt electrolytic cap connected inside the rectifier circuit.

Plugger into a wall socket.

I shall wear a safety shield mask and gloves....

Line voltage in Mexico is rated 127 vac."

4 x 33V = 132V
voltage across LEDs 1.414 x 127 = 180V!!

"Mushroom Cloud Over Mexico LED Magic Smoke Tomorrow"!!

Beats watching Juanita steal Carmelita's husband through treachery on Mexican soap opera TV.

you don't have a favorite "TeleNovello"

You mean that warm glow to the south wasn't you? What about your birthday, did they light a cake?

A pic of your items on a bread board, before going into production, is in order. Sounds like fun.

You will be for sure pushing some heat when you get even 26 amps at close to 36V with those LED's. And those lights will be burning quit bright too, at that amperag and voltage. 36V forward voltage is the goal with those LED's, varying the amperage at 36V input affects the brightness and heat the most. In a basic 3.6 to 4V Led, 700 milliamps is a good balance of power input to light output, for longevity. For additional brightness, with a significant gain in heat output, and heat sinking necessary, 1,000 Milliamps is quite good. The amount of lumens gained per increase in MAh, past 1000 is a trade off of being over driven, creating lots of heat, and shortening of life, for not that much gain in lumens, for current expended.

This was true around 2009- 2010 when I was dinking around with lights for riding mountain bikes at night on single track, trying for 600-700 lumens out of a single die LED. YMMV with increases in performance of LED chips 5 years later.
