Nice QL Lamp and Ballast.

Personally i think that all Lamp Bans are idiotic,the idea of telling us we cant use this lamp type just cause its less efficent is highly communist in nature...really what good is it going to do?

i believe i heard somewhere the compact nature of these makes them run on the hot side and loose some effiency....so i think Icetrons might be a better design,even though the QL's being compact would be better from an optical standpoint.

QL's have to be mounted to something, what might serve as good heatsink (the base of the "socket" is the thermal contact area, from here run the heat-pipe up to the coupling coil to keep this and the lamp itself at reasonable temperature).
Icetron's concept has no such heat sinking requirements, but need special optic (QL suffice with "coated MV" optical assembly)

Light it up!

Nothing like the beautiful cool white light of a coated Mercury Vapor lamp and the soothing hum of it's magnetic ballast.

ICETRON is Osram's ENDURA in Europe is it? I've seen QL like technology in my country they look like HID bulbs just that the metal crown just above the screw base gives it away as induction lighting.

Im not too sure on these....I was asked to look at "defective sales floor lighting" in a local commet store a good 3 or 4 years ago now and what i found was about 30 dead QL lamps only difference was that they had rings around the lamp! It seemed to me that the electronic drivers had died! The price to repair was astranomical and i belive they ended up getting their own maintenance team down to second what i found who also ended up carrying out the repairs!

@imj: ICETRON is US trade-name and ENDURA EU trade name for one and the same system manufactured by Osram/Sylvania.

Attention, the QL systems in Europe are very efficient, I know that work for more than 100 000 hours without any failures.
The supply voltage is important in these electronic systems without counting the many Chinese copies that circulate in the world by copying exactly the same technology from Philips (Venus Yonghuang ,...)

@selemium The QLs that comet stores use are not going to be cheap chinese copies they would never use cheap stuff they were philips! Also the supply was Telemecanique Canalis Busbar system so there was not a voltdrop issue!

@Selenium: Not only copies but their own "improvements" on the QL design. Like I mentioned they use those HID shapes which have lost some brightness after being used for some months some even exhibit colour shift. Overall the size to effiency/brightness of the China lamps is less than a Spiral CFL.

I think the reliability of these QL would be strongly dependent. how you install and/or incorporate them into the fixture design, mainly the thermal management.
The 100+khour life apply only for correctly installed units (e.g. in cast aluminum fixture, the coupler bolted tightly to the main fixture material).
But if you do not heatsink it, the coupler get overheated and may fail soon (and take the inverter with it; e.g. in small, fully plastic fixture with no ventilation it will die very quickly after few hours)
