Mercury recessed can at supermarket

Mercury recessed can at supermarket

Click to view full size image

Went to a different grocery store today than my usual, this was at a Kroger, in the front lobby area where you get shopping carts. There were probably 20 or 30 of these 6" can lights. Only about a third of them still had mercury lamps, the rest had various CFL and LED par38's which were obviously spot-replaced as the mercury lamps went out.
The mercury lamps appeared to be maybe 50w or 80w, very dim and greened-out, several were flickering badly. Two were so dim, they may have only been emitting 300-ish lumens.

If you enlarge the photo, you can see how grainy the phosphor coat is on these lamps. So maybe EYE Iwasaki?

EYE lamps don't have that little hole on top.

Any machine is a smoke machine if you operate it wrong enough.

Cool to see!

Good quality things are awesome. Cheaply made things are not.

Might be a Tungsram. I have a 50w and a 80w which look like this, complete with the ED dimple.

Always nice to see an MV reccessed downlight still in use.

Nice! Wasn't 80 watt only a European thing?

Yeah but there were yardlights marketed here with 80w lamps. The shape on this one does look more like a 50w lamp though.

They could be 75w lamps.

While the vast majority of mercury recessed cans like this were 100w, these just seemed far to dim to be. But, for all I know, they could be 100w with such blackened arctubes that only a small section of the visible arc discharge can be seen, giving the illusion of a smaller/shorter arctube.

I have seen installations of 80w mercury lamps here in the states, but they were outdoor post top lights. I honestly cant say ive ever seen 50w in use anywhere though, I think the 50w size was probably less popular with the introduction of compact fluorescents

I'm just going to say these are 50w since the bulb envelope is so small and the arctube looks really tiny. If possible, see if there's some way you could save the ballasts from these when they retrofit. Maybe offer to do a retrofit with a bunch of LED lamps for free or super cheap in exchange for the ballasts.

Since they are the only store in the area that appears to keep essentials stocked, I will be going back. Ill have a closer look when im back there and perhaps talk to someone in management

Yeah I agree with the envelope looking more like a 50w lamp in size. Saving the ballasts would be pretty nice. I'd imagine these use f-can ballasts.
