Water Cooled MONSTER 1500 watts

This build was started almost a year ago now and is still ongoing, just one of my long term projects.
This build was never intended to be practical, its more the enjoyment of creating it and getting a functional “sculpture” at the end.

20x Cree CXA1850

1 of the 2 240x60mm radiators

The Solenoid

Reflectors, what is the purpose of the cone things inside the reflectors?

Most of what is going into it.

Can’t wait to see more of this!

No idea what the centerpiece is in the reflector - is it just hollow?

You are one seriously crazy guy. Love what your doing. :slight_smile:

can you make an EDC version of this?
j/k this is amazing.

are you lighting up the mcg?

The cones in the reflectors keep you from seeing the LEDs directly. They might either reduce the spill light around the hotspot (if they are lenses) or they might make the spill even wider (if they diffusers). The might also be cone shaped reflectors which redirect the light to the main reflector, also minimizing the spill.

Subscribed, can’t wait to see the build process. Thumbs up from me :beer: .

Wow cool! :+1:

Has anyone tested one of these high power COB style LEDs to see how much they can be over-driven?

You could get similar power draw and higher lumen output by using three Citizen CLU550 LEDs :slight_smile:
Up to 70k lumens 500W each. https://www.digikey.ca/product-detail/en/citizen/CLU550-3626C1-65AL7G4-B24/1642-1198-ND/5820567

Here’s my (German) thread where I calculated that.

Guinness world record is coming. LoL.

Crazy build :slight_smile: :+1:

you might run into pump trouble. 1500W with 2x280s will surely exceed the maximum allowed Pump temperature.

Where is the pocket clip?

I can’t wait to see this. I’ve wanted to do a build like this for a long time, but didn’t have the resources. It’s good to see someone actually doing it.

That shouldn’t be a problem if the pump is after the radiators unless the radiators can’t provide adequate cooling.

Subscribed!

the water temps in such a loop don’t differ much before and after the rads because of the high flow rate. Single digit K at max.

It’s a common misconception that you get “cold” and “hot” parts in the loop.

The bigger the difference between coolant and ambient, the more heat can be removed by the rads, but this is limited by the pump he chose

You gonna track Elons Roadster with it?

Nah, I calculated that myself over a year ago :slight_smile:

When you drive it at 2x the base spec you get the 500W 70k lumens.
Still really good efficiency, over 100lm/w, assuming it is cooled properly.

Temperature difference before and after a radiator is a fraction of a degree, unless you have a really weak pump and low flow rate.
