Here's a interesting Thorn KolorSon coated HPS lamp from Restore, it's made in Britain and the base looks like a E40. I wonder how it got to Canada.

for some reason......I like Coated MH but Coated HPS Is odd to me.
streetlight98   [Jun 17, 2014 at 04:35 PM]
LOL yeah I'm the same way Devonte. I like coated MH since it reduces glare but coated HPS just seems odd to be too lol. Coated HPS lamps are rare though and especially finding a European one in North America! Shocked Very Happy Nice lamp! Will E40 lamps screw into E39 sockets and vice versa? What about E26 and E27?
joe_347V   [Jun 17, 2014 at 11:51 PM]
Yeah, I rarely see coated HPS too. And I also don't know how this British one ended up at Restore lol. I believe it was a tighter fit but it did screw in to my standard E-39 socket. Same thing for the E-27 lamps. Not sure about the other way around. I suppose I could try since I have a E-40 and a E-27 stashed away lol.

Coated HPS Lamps are popular in Europe right?
joe_347V   [Jun 18, 2014 at 06:54 AM]
I believe so, it seems over here they largely remained a specialty lamp.
Form109   [Jun 18, 2014 at 01:51 PM]
what special purpose would a Coated HPS Lamp serve?
joe_347V   [Jun 18, 2014 at 05:40 PM]
I believe in most cases it was the same as coated MH, to reduce glare and diffuse the light better. They were also used (mostly in Europe) to refit fixtures designed for coated mercs so that the light distribution stayed the same.
streetlight98   [Jun 18, 2014 at 08:37 PM]
Yeah coated lamps would provide the same distribution. The reason MH lamps are more popular coated is from highbays that have a clear lens or no lens on the bottom. Clear Mh lamps are painfully glarey indoors, yet I see the clear MH lamps used more often indoors.

A lot of glare problems would be solved if coated HPS was more commonplace, the hotel I stayed at last night had coated 400W HPS lamps in prismatic highbays over the swimming pool Shocked
streetlight98   [Jun 19, 2014 at 02:22 AM]
Ew! They shouldn't even make HPS highbays. Rolling Eyes Laughing All I can say is that i bet it's a tough job fixing the highbays when they're mounted right over the pool lol.
A_lights   [Jun 19, 2014 at 02:38 AM]
I agree!
Form109   [Jun 19, 2014 at 03:18 AM]
I've seen HPS Highbay's in parking garages,and I generally find it pretty unacceptable for that purpose...like the AutoZone's back in tyler had recessed can lights outside the front store entrance with HPS Lamps that looked about 200/250 Watts.

certain places HPS Just shouldn't be used IMO.
streetlight98   [Jun 19, 2014 at 04:18 AM]
If someone really wanted to, they could call out HPS as a safety hazard in a pool area because people's tones are distorted. Like if a parent is trying to keep an eye on their kid with green swimtrunks, it's gonna look brown or black under HPS light. I find that HPS doesn't light wet areas too well either. When it's just rained and the roads here are wet, the HPS lights are useless because the light doesn't even show up on the pavement. HPS does very well lighting up the roads in snow though. But it makes the snow look like orange sherbet. Laughing
joe_347V   [Jun 20, 2014 at 05:14 AM]
Yeah I rarely see HPS highbays too, I think the only ones I know of are in a parking garage. Most pools here use MH or fluorescent fixtures.

I have a HPS highbay. Razz
streetlight98   [Jun 20, 2014 at 07:25 PM]
Man Darren, you have a DuraStar and now a HPS highbay? Razz Laughing
lite_lover   [Jun 21, 2014 at 01:33 AM]
