I would imagine that in the extensive pages of L-G is some sort of information about every type of phosphor ever used in a mercury vapor HID lamp. Problem is, where to find it all.

I'd like to have a quick reference list of all the suffixes, ie, "/DX", or"/N", etc. and what type of phosphors used, what type of light produced, efficiency, and application.

If someone has a link, or is willing to create such a list, I'd love to hear about it. Maybe there is already a list in this site? Thanks.

Also, I'd like to hear various comments and opinions about all the different kinds of phosphored lamps ever made. I think it would be cool.

Don, here's a list from my memory:

/DX - yttrium vanadate phosphor. Adds more lumens and color rendering than a pure mercury discharge

/C - magnesium fluorogermante phosphor. First commerically available phosphor coated mercury lamp in the USA. Soft and pleasant appearance and color turns greenish later on. Lumens are slightly less tho.

/W - zinc orthophosphate phosphor. Second commerically available phosphor, having come out in the mid fifties. Adds lumens but lacks a strong red spectrum.

/N - phosphor blends depends on the manufacturer. GE Warm Deluxe White lamps had a double layer of /DX phosphors. Westinghouse Styletones had a layer of /DX and a layer of /C phosphors plus a third layer of silicia, the type used in soft white incandescents. Sylvania /N lamps are similar to Westy's but had a yellowish filter. Gives a nice warm color but at the cost of efficency.

/Y - caution yellow. They were /C lamps with a yellow coating on the outside of the glass bulb.

/X - the very first deluxe white lamp. They used /C phosphors with a red-purple outer glass bulb. That allows even more of the red spectrum, but at the cost of efficency.

/R - Westinghouse's exclusive Beauty-Lite merc lamp. They had a layer of /DX and a layer of strontium orthophosphate (if I remember correctly) phosphors. You get high efficency (same as /DX), a soft aand pleasant light, and good color rendering in the red portion.

Thanks Dave...I know a couple of these but I always come across one and draw a blank. This'll help me out. 

this helps me out alot too!

A phosphor is a substance that exhibits the phenomenon of phosphorescence, a sustained glowing after exposure to energized particles such as electrons or ultraviolet photons. And ye, I want to complete list of every kind of phosphored M.V.

Here's one of my favorite links for reference.

@don93s: Super flourescent lights . They are very smart.LOL
What kind of website is that??

Here is the homepage of website.

I believe one of our members (James) has it.

He should repair it. It´s surely only a mistake. I´m very sorry. I thought this is a profit-making site for lamps, but thanks to don93s I know the whole website and it´s a very good site.
I find it good that there´s such a website.

Actually, in many places, phosphor coated mercury vapor lamps are refered to as 'fluorescent'.
