100 Watt LED Chips - Best Quality Brand ???

[JetPilot]

I see a lot of cheap 100 Watt LED chips for sale that will burn out in very little time. Does anyone know which brand is the best, longest lasting 100 Watt chip ??? I put a lot of time into this project, I do not care about price, I would rather pay more for the LED and have it last...

Also, anyone know the best constant current driver that would make these work at 12 volts ?

Maybe a Cree CXB3590-0000-000N0HCD35G, available in the US through Digikey for around $60...

The Bridgelux Vero29 is also another great option with arguably better color rendition.

CXB3590 is a top choice but if you want to run at 12V you will need a boost driver as most large COB's start at 36V drive voltage, however $60 is a ripoff, much cheaper elsewhere

Good to know. Where and what price?

Thanks for the information, I love CREE LED's, I use them in all my projects ! I was not aware that they made a 60 watt LED, but I will go with that. Now just to find a 12 volt driver for it.

Hi Mark,

I would rather pay more for an LED that is not going to fail quickly, I would never trust the 8 dollar ones ebay, that would be a huge waste of time, and also a waste of 8 dollars also BUT 60 dollars is seriously overpriced... Any suggestions on where to find the CREE ones cheaper ???

...60 watt LED...

Of course it depends on your heatsink and ambient temperature, but the CXB3590 devices are good for more than 60W...

Poke around all their offerings, and be sure you get the CCT and CRI that's best for your application. There are tradeoffs in these specs, and it's not a matter of any particular device being 'best'. The $60 is the typical distributor price for these in single quantities. I'm anxious for Mark to back up his claim too...

PM me for details, one of the nice things about running a 3590 at 60 watts is your wall plate eff is around 50+%

I have made great experiences wit very cheap LED modules. The key is to run them at half of the rated power. The ones I used in my desk lamp project are running great for years now without any signs of degradation.
