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

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?

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.

Wow cool! Thumbs Up

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 Smile
Up to 70k lumens 500W each. https://www.digikey.ca/product-detail/en/citizen/CLU550-3626C1-65AL7G4-B...

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

you might run into pump trouble. 1500W with 2×280s 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.

The low mode should be lower.

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

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.

Cones are hollow.

Over 100 volts could be an issue though Silly

Its an EK pump that cost me AUD $120ish so the quality is there.

I know, I’m using the same pump. Maximum coolant temperature is specified at 50°.

1500W with 2× 280 rads will exceed 50° coolant temperature. If you only use it for short(ish) bursts and do not let the coolant reach maximum temperature you might be ok.
Adding a coolant temperature sensor + display (these are available for under 20$) might be a relatively easy fix, so you can switch off or reduce power when it aproaches critical temps.

Weird!
Maybe they are only supposed to block one’s direct view of the emitter?
