By your data I was pretty surprised to see how fast all lamps will depreciate but wow do the metal halide fall off fast and I've spent more then a small fortune on re-lamps over the years. :rastasmoke:

On another note; have you or possibly anyone else here heard of these new LED's that are organic? They're being called OLED lamps as a solution to the HBLED lamps being too concentrated light output.

From what I understand they are being coated with a phosphor or polymer to better manage the optical distribution to better diffuse the light and resemble a fluorescent lamp while maintaining color stability in the process.

I realize this isn't an induction lighting question but then again it appears that if the OLED develops as an option which would completely eliminate the need for any lamp that requires inert gas mixes and Mercury to operate you would be interested in the science behind it.

If LED mfgs develop OLED lamps that will outperform other technologies then it creates greater acceptance in the marketplace especially of the price points come down as can be expected (Haitz's Law) and the new color quality scale (CQS) is adopted as an updated standard for weighting the hue and saturation levels of any lamp we consider buying.

Any ideas when the market may be seeing these OLED lamps at competitive prices?
Hi Brynpav

A little slow getting back to this forum so forgive me any delays as I've been pretty slammed.

I'll respond in the order you've questioned. The lumen deprecation schedule we provided does make a pretty good case for the average lumen output of these lights being above 90% until the 70,000 hour mark whereby it then will gradually fall to the 70% mark at around a 100,000 hours.

As to the OLED question I have some opinions of this technology but would differ to khyberkitsune who looks to have a deeper background in LED/OLED development. However there does appear to be a field of research devoted to seeing the OLED lamps used in high output area lighting applications.

I would refer you to a recent article in the October 2010 EC&M, that discusses the high output advantages of OLED technology which may someday be of some interest to the botanical market but it's certainly way to early to tell what if any those applications may be.

Thank you for your comments.
