We were asked to look into some specialty lighting for a few applications and provide a bid. However, I just cannot get my head around ALL the products available and their ratings are all over the map, making it ridiculous to wade through all of them.
We really need to drive these efficiently. Approx 150lm/W, and not use a million diodes to do it. I have looked at several of the Cree offerings but I really need a list of less known brands we can consider because as of right now, Cree is just out of the budget unless we can find something else in their line that will work. For instance, they list a 13W LED and 170lm/W. Then you get in there and realizing you have to drive it at 1W to get 170lm/W and it is down to like 90lm/W at 13W. I mean, they would work, but certainly NOT for several dollars each! I suspect lots of these markets are looking at non-continuous use where efficiency is less an issue.
I am familar with Osram and Lumileds so far. Looks like Lumileds and Cree have conspired to match each others price because they are both expensive.
I would really prefer higher drive voltages but we can probably work with what is otherwise a better fit.
We are looking at lights to be installed inside large assembles during the assembly process for a 24/7 operation. They will need operation table light levels with good CRI so we need to push, but we need the efficiency to reduce heating in the area.
