Hey glad you like it! July 1985 is the date of this lamp. If this thing were put into regular use it should still last almost as long as the Westy lifeguards. AFAIK the arc tube design of these was the same as the last Westys. LOL yeah must be one of my mom's pairs of shoes. I've had this box awhile. I used it to paint in the garage in the winter, since the box contains the spay mist better.

I have the 175w version of this lamp. It was actually one of my first HID's. Do you have a fixture for this or are you going to build something?

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

I might end up building something... It won't fit in that GE 100w fixture I have and the PSMH bucket I have had a medium base... Since the refractor assembly is busted on the PSMH bucket I may just pull the ballast out of it and use it in something I build for this bulb... Either that.. Or I attach a Mogul base to the PSMH bucket and find a new assembly.. But I don't know of any good easily accessible and abandoned lights to pull an assembly off of...

The clear mercs never kicked off here either, at least in the Northeast. Aside from small numbers, the clear lamps never saw use by any of the major utilities up in this area according to a local enthusiast. Typically municipal utilities used them here.

All the larger lamps (250W and up) were available in clear tubular or elliptical coated, we rarely if ever saw clear elliptical. The early HPMV lamps here were pearl (inside frosted to you), like this one (sadly not mine )

Ooo very nice! I love inside-frost lamps. A MV variant must be very cool! And a PS envelope to boot!

Clear MV's were all the rage here in greater Seattle until the mandated change to HPS in '83. Now, one only sees them in residential applications, and those are disappearing fast.

Your mission - should you choose to except it - is to save unique and rare HID lighting before it's all scrapped.

What I find strange is that this lamp was never made by Westinghouse (they only made BT's), yet Philips put their name and logo on the sleeve.

Could they have to for patent reasons or no? Unsure how that works... But yeah interestingly they kept the Westinghouse name until the end of the 80s. Possibly as a marketing tool? Would make sense, that way people who were loyal to Westinghouse or "Lifeguard" lamps would associate those names Philips.

I used to have some Philips branded BT28 lifeguards... is it possible that also sold 100w BT25 lamps under their name?

I actually have a Philips BT-25, it's a 70w HPS from 1986 and it's branded only as Philips. Both on the etch and the sleeve. It's possible IMO that they made BT-25 100 mercs too briefly.

Hmm they must've dropped the Westy labeling soon after this lamp was made then! A BT25 from 1985 is interesting, as these are ED23.5 from 1985. I wonder if they offered both or if they for some reason switched the MVs first?

Mine is a Canadian model though, the sleeve says "Made in USA" but the only address on it is Philips's Canadian office. Maybe Philips never got the rights to the Westinghouse name in Canada so they just rebranded the lamps to Philips a lot earlier in Canada compared to the US.

Yeah I wonder when exactly did Philips ditch the BT-25 shape, it's possible they switched the MVs first too.

The lamp above was originally made by Philips at their Hightstown, NJ plant (Norelco).

I've seen Philips H38JA-100/DX in the BT25 format with a date code as late as 1987. I think I have one from this era as well...just never posted pictures.

Because it's hard to shave with a lamp.

Nice! I have the 175w version of this lamp. Rattly arc tube but Lifeguard type arc tube and electrodes. They last about forever it seems.

I think mine is from about '93. The washing machine on the spin cycle or the stereo's bass vibration will make it rattle!

That's mine alright. Used to have a yard blaster light with that lamp next to a back door...slamming the door would make it rattle.

If I have a Philips lamp in my street light in my bedroom I will rattle when I walk in the room. It's no wonder these lamps often have failed welds when exposed to excess vibration. Where are my girder frame mercs at?
