New LEDEngin 90 Watt LED 5400 Lumens @ 1000ma

[matrixshaman]

I see LedEngin has a new 90 watt LED in cool, neutral and warm white. That's 5400 Lumens at 1 amp in cool white ! They are saying it has high CRI performance also. See some more specs and pic here:

Reasonably efficient at 350ma. Seem to run out of steam when pushed to full power. Diminishing returns? Should make a nice floody 30w competitor to the SST-90.

Cool/Neutral/Warm have CRI or 75/80/85 which is pretty good.

My 50w outdoor LED floods will need new LEDs in a few years. Add this LED to the list that I'll have to choose from... Citizen, Bridgelux, Sharp, Edison-Opto, and now LEDengin...

Specs seem goofy because it's expensive and not very efficient.

Plus it's cute how you have to dig around the to find Vf.

The Bridgelux RS can push over 5600lm in warm white, 7000lm in neutral white, and over 8000lm in cool white at about 86W (and can be pushed harder). About the same price too.

Hmm speaking of goofy, they list a UV LED LZP-00U600 that outputs 3300 lumens at 365nm. Considering the lumen is by definition partly a consideration of the human eye's response to various wavelengths and that the eye doesn't see anything at the 365 nm wavelength, the lumen output should be zero. UV LED's are normally rated in milliwatts not lumens, just for that reason.

I'm thinking that is milliwatts, they just goofed on the website there, as the LZ1 series is listed in lumens on the webpage but miliwatts in the datasheet. Jeeze, 3W output of UV is a ton.

That would make more sense.
