The May/June issue of LEDs Magazine featured an article entitled “Asking the right questions helps to educate customers and suppliers alike.”
In a continuing effort to advance SSL market transformation, we thought it beneficial to request and receive comments from our readers that may serve to further benefit and enhance the procurement process and protocol.

Good to know that there is such a blog talking about LEDs. The technology is going to be a big hit in near future.
Photometrics are important, but no less important is to know how the photometric data were obtained. It is absolutely critical to ensure that the LED products are characterized with a spectral instrument - filter-based photometry consistently yields huge errors when applied to "peaky" sources like LEDs. As a representative of an independent testing facility, I've seen manufacturers use light meters intended for photography and report values that do not in the least resemble reality.

I can recommend another good seller of led lighting products in England – http://nasena.co.uk
I see they have good conditions for delivery and till 3 years warranty period.
I think most customers, when they're looking at LED lights, are trying to compare them to what they know: incandescents and CFLs. so it's important that there be an accurate and not-too-techy way for manufacturers and sellers to make a direct comparison to conventional bulbs, specifically about A) how bright an LED fixture is, B) how much power it uses and C) how it looks in terms of color temperature, etc.
This is attempted with CFLs, but I always find the "60W equivalent" bulb, for example, to be a little dimmer than I expected!
