Though I'd drop by again -- and this time I've brought a some market research. Had a little down time at home and at work lately, so I've compiled a spreadsheet covering a few of the more popular LED manufacturers' specs and prices.

I'm in the market for a substantially large LED purchase, so I've been trying to use this data to help me choose one model over the next. Still, there are some major flaws, not the least of which is my total dependence upon the manufacturer's specs, rather than the standardized testing of an unbiased, third party. My spreadsheet is also limited in its scope with regards to both manufacturers and vendors. The price/output analysis is also geared towards value for lumens/milliwatts, rather than efficiency or any of the many other important factors.

Still, I've found it useful to line all these products up next to each other. Let me know if this data is useful to anybody else on the forum. If so, feel free to suggest new manufacturers and vendors you might like added to the spreadsheet, or new forms of analysis that might be interesting. All of this was created in Excel and exported as a PDF for use on this forum.

Thanks again for all the work that's been put into this thread and others.
