Which one you like better for HPS, coated or clear? I like the coated version cuz there are less glare.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).

LED brainwash? No, people uses them cuz they work well for them.

I agree with DP.......BUT Coated is better for FCO for less glare...same for drop refractors and sag lens.......but DP is right......its fun to see a HPS make funny effects when starting up...not all HPS start up the same LOL

I prefer clear HPS lamps; better focus (as most are used in floodlights) and the lamp looks nice when turned off. however, if the lamp is hidden from view, particularly in a post-top light, coated is better. In downtown Seattle, most of the posttops have clear lamps, and you can see the bright spot of the arc tube - I don't like that. At home, all my HPS lamps are clear except for one fixture, which I will keep using coated lamps in as long as I have a supply. It appears that the coated HPS lamps I have actually use a phosphor - you can see the red glow at start up and when the unlit bulb glows red under a blacklight.

I mostly have clear HPS at home.  I currently have one 70W Philips Ceramalux OEM that is coated.  I also had two 35W bulbs that where coated.  One was a Lucalox and I'm not sure what the other one was.  One of them was installed in my old house when it sold.  I'm not sure what happened to the other one.  The coated ones seem to be harder to find today.

I like the clear better,you can see the arc tube characteristics at start-up and lamp is brighter.

The brighter the better.

Quote from: gmercury2000 on January 02, 2009, 05:33:03 PM I think coated would look better in an FCO fixture as you would get a softer light distribution where as with clear lamps you have bright and dark spots depending on the reflector pattern. As for clear lamps in a fixture with a refractor clear lamps are ok. Yeah Geoff, if you look at the FCO or Sag lens coated mercs they do a good job lighting the road.....so HPS DO need to be coated.....think you can make that happen?

Why aren't nobody using coated HPS? There is only ONE place I've seen them. How often are coated HPS used in europe?
