Can These Prices Be For Real???

All single ended (mogul) bulbs are enclosed in glass, thus no need for additional UV shielding. Only double ended lamps need to be behind glass for UV shielding.

I believe you are mistaken. Not all single-ended bulbs have UV protection.

I could be wrong, I have been wrong before....but....every single ended mogul 175w and 250w bulb I have ever used (for the past 18 years of home and shop use over fish tanks and in warehouse) had the envelope enclosed in a glass bulb which provided UV shielding.

Anyway, I am really interested in the quality of the 250w 20K Plus Rites.

Uncle Salty, I have been running the 250W 20K bulbs since march. No I'll affects so far. I didn't have a lot of super needy light stuff at the time so I thought what the heck can't go wrong. I bought mine off eBay for 20 bucks apiece. I've had great luck with them, I keep an LTA, and a RBTA, zoos, ricordea's, candy cane, clam, and a few other corals under them now, all showing good color and growth. Haven't had any algae issues show up either. I typically run a 14 or 15 k bulb, but a lot of the reviews I read said that they aren't as blue has a name brand bulb so I went with the 20 k and love the color.

Yes, the 20K look more like a 14 or 15 K bulb.

any single end bulb has a shield over it, the inner piece that looks like a DE bulb is what needs the shielding, provided by the outer piece of glass.

I skimmed through here and didn't see anyone mention it. There was a pretty lengthy thread on here about a year ago, and someone had tested the par on these when they were new, 3 months out and 6 months out. They help there par levels almost too 85-90% @ 6 months out, but they did mention that the colors were a bit lower in kelvin than advertised (i.e. 14K was closer to 10K, but still had some blue...like 11-12K). I cant find the thread, but its on here.

Maybe use google operators to search this site for it, im sure with 10-15 minutes it could be found.

The 250w 20000k metal halides are a little blue, but my corals love em. The tank seems to be much brighter than with other more expensive bulbs. I love em!

Plusrite bulbs are garbage. Please do a search on them before you buy. Know that they are inconsistant and the PAR drops off quickley.

I have used them before also and had PAR tested on several 10K, 14K, and 20K bulbs.

The 14K type seem to perform the best out of the 3 but does not compair to other bulbs.
