Today at ledvance i saw they phasing out all types of ceramic metal halides excluding e40 base 100w, 250w 4y and hci-ts 150w ceramic lamps, why they decide to start ban ceramic mh lamps first other than less efficient quartz lamps?

This is the idiot LEDVance company that decided to discontinue production of their CMH lamps. The EU lamp ban aren't related to this.

You had to ask..? The clue is in the first three letters of the company name

I think that I would use word from James May for Osram

They are not banned, but since they are mainly for streetlighting the sales volume of these has dropped practically to zero during the past two years.  Other manufacturers have also severely rationalised their ranges, and some only offer now a few of the wattages.  I think maybe within another year or two the E27/E40 capped ceramic metal halides will disappear completely because it's no longer viable to keep the production running when the sales quantities decrease so much.

I hope that my comment hasn't triggered you.MH lamps are good and have nice colors.

As has already happened with SOX. Another sad day to "look forward" to, then

To be honest that is reason why I collect bulbs,because in the efficiency world nice lamps with style would disappear.

Same here; sadly it's all we can do now, the ball is rolling and cannot be stopped

Sad, these are nice lamps. Hopefully this makes other manufacturers like Philips keep them in production longer as they can take the market from Ledvance.

Although I have a strong liking for CMH lamp technology, to me, CMH lamps for street-lighting purposes was a bad idea given the slightly shorter lives compared to HPS. I have seen strings of CMH street-lights being retrofitted within 2 years, due to their bad failure rate, to standard Na-Hg-Sc metal-halide lamps, finally to Philips EnergyAdvantage lamps which have a unique and readily identifiable spectrum. Chicago's CMH 2010 retrofit program of more than 16,000 street and lane-way lights were such a waste.

[Looking for energy efficient lighting for its alleys and streets in 2010, the city of Chicago chose CMH lamps, thus becoming among the first large US city to extensively employ this lamp technology. By August of 2011, Chicago completed installing 11,000 CMH lamps in 482 km (300 miles) of alleys and 5,300 street-lights on Lake Shore Drive and Western Avenue.]

Time to stock up!
