According to post #592 there are two of these phosphorous disks for sale
You bid $10 on only one of them hence my bid remains $5 on the other one.

are NOT phosphorous disks !!

They do not catch fire in open air. These are made up of a Phosphor material that absorbs the 445nm light and re-transmits it as green light. much the same way as Sodium Flourescine and UV light.

The word is Phosphor, which has nothing to do with element Phosphorous.

Could someone give me a vague idea on how much these will go for in a kit form once builders get their hands on them? For example, with driver, mounted optics, and heatsink? Is <$100 resonable?

The word is Phosphor, which has nothing to do with element Phosphorous.
Phosphorescence - Wikipedia, the free encyclopedia

The very term phosphorescence refers to the ability of substances to glow in the dark in a similar way as phosphorous does weather or not the substance contains the element phosphorous.

For the record I'm just using the seller's terms which was originally
written as "phosphorous wheels"

Default Re: *445nm lasers* !diodes 38.50$!

just to let you know i get a message for 50$ for each projector after the arrays.
So just to let you know if the gutted projectors dont come together to be 50$ he will be listed as the highest bidder.
So i will try to update the op later today as i found a good ie connection at my cabin.
sorry for my absence.

Check for the prices of the empty projectors on eBay, I think I read that they go for a decent amount of money there.

Paraphrasing from the link (Fluorescence - Wikipedia, the free encyclopedia): the ring is lined with a coating of a fluorescent material, called the phosphor, which absorbs the blue laser light and re-emits as green light. Correct?
