A Chinese "Sparkle Lighting" branded CFL that was located in the past in a fast food chinese restaurant in Canyon Haifa mall. The reasons why i think that this lamp based on halophosphors are: 1. Very pale and awful light 2. Much lower brightness then most regular daylight 865 CFLs (When i first detected it). 3. My CD-R revealed a spectrum consisted of only the mercury lines on a background of continuum (Not a triphosphors spectra). 4. Very fast phosphor discoloration (Blackening). Now the most important thing: The reason for the unusual coating (Which i considers it halophosphors) is not because of the age of the lamp (Indeed, this is a present lamp that are still made today), but becuase the factory tryed to lower the cost of the lamp as much as possible by using a low cost phosphors while ignoring the quality of the light and the performance of the lamp.

Dors, Hey how many watts are they...I acutally know a few of the lamps like this and they probably are halophosphors, because you aren't the only one that mentioned it.....I remember some people telling me there were some cheaply made ones made out of halophosphe from the dollar store...so I completely understand where you are coming from....and why you suspect it....because I have a lamp from a dollar store which is 6500 K color and it was BRAND new...turn it on...its REALLY dim and pale...but it's not always awful...it's actually less glary towards eyes and its good for if you LIKE the color and you don't want it to be too bright...but agreed, less efficient for INDIRECT light...

Yes, the dollar store offbrands sold here are halophopshate. They are quite dim. They lack the energy star certification.

15W or 23W estimated. Yes, this is a flea market (Dollar store in Israel) CFL lamp with an estimated cost of only between 9NIS to 15NIS. Barely larger then incandescents cost.
However, you will be surprised that in Israel, the local ACE shops also selling them along with the annoying "LUXTEN" incandescent "Arcing" (When they reach EOL) lamps and "FLASHLIGHT" CFLs.
The US ACE chain of shops in Israel is not as good as in the US.
This lamp indeed don't glare like most CLFs.
But the best way to find if it is halophosphors is to check the spectra.

The whole building is gonna sparkle when this shorts out. Cool

This is depends if the lamp is standing with the israeli standards.
If you are a member in LG, and i sure you are, there is a member also from Israel, Ash, that is expert in computing and electricity and therefore can explain you reason for electronic ballast frying in 230/240V countries. These are different from the US and much rarer (As the reason for electronic ballast exploding in the US, is a part of the lamp EOL. Lamp filament fusing uses voltage doubler that causes the electrolytic capacitor to overheat and explode).
Generally, exploding and/or frying of electronic ballasts of CFLs in the US, IS their main EOL mechanism, while in 230-240V countries (Such as Israel), this is much rare and caused only by manufacturing defects (Ballast short for example).
At least, this lamp ended their life peacefully, but, as excepted, only after a 3 months.

You know, I'm pretty sure that he was just joking about the brand name. Rolling Eyes Laughing

I was only joking, yes, but CFLs can and do start fires. Shocked I've tried to tell my parents not to use CFLs, but I had to show them som pictures into scaring them not to buy them. I am a member of the L-G, but I haven't been active for some time....
