sounds a little conspiracy theory-like to me. CDM lamps can put out similar spectra of light an they don't get the same rep as LED. although CDM is a better tehchnology imho. Handles heat better, lasts longer outdoors and the ballasts can last as long as your average human if well maintained. although the lamps certainly can't. 16,000 hours = BOOM but it's still longer than an LED fixture!! there are a few near me and I calculated their life from +/- a week since switch-on... 8,000 hours and 2 units had already dropped out. that's not even on-par to the world's cheapest MBI-U!!!

What if I told you you could save 100% of your street lighting budget? Don't believe me? Buy an LED street light and run it for a week. the results will leave you in awe. (Aaaaaaand maybe wondering why you swapped that 70w SON)

Mercury vapor lamps are 4000K like most LED lights. Where where the worries about sleep disruption then? It's idiotic.

uncoated lamps are closer to 6000K... and if his argument pertains to low color rendering then...

HOW COME MERCURY VAPOR, HIGH AND LOW PRESSURE SODIUM AND EARLY METAL HALIDES HAVEN'T BEEN SUBJECT TO THE SAME TREATMENT?!

To be fair, there's probably more blue light in 4000K LED. I really can't stand LED light any cooler than 3000k but the color from a /DX MV doesn't bother me and I actually find it quite pleasant. Same with fluorescents/CFLs.

LEDs = Downgrade 99% of the applications.

There is but the CRI is worse. It's closer to 30 or 40 where a good YVO or DX mercury is about 50-65

@ F96VHO: No, it's roughly 4000K for DX and 5700K for clear MV.

But the clear MV appears green which I thought was a color temp above 6000K

Despite what you may think it is, according to the specs on manufacturers' websites it's 5700K for most clear MV lamps and 4000K for most /DX lamps. Some manufacturers use different kelvin ratings though. Sylvania rates their clear MVs at 5900K. Remember that color temperature applies to NEW lamps. Clear MVs are not greenish when new, they are primarily white, with a noticeable amount of blue.

yeah I'd call it Ice-blue. I have a few regent clear mercs. they seem to be lightly used and light that bluish white you speak of.

My 50w OSRAM with damaged phosphor is the same. it's paper white with a blue cast to it... makes you look like a zombie when you put your hand under it though because it makes things look green!
