You could also use a 200w A21. I know if I had one of these I might actually consider a large CFL (yeah, I know)...

Don't want to use 200W. Believe it or not, this was actually pretty bright at night with a 150W lamp! The lamp is rated at 2000-something lumens (over 2500 anyway) but it's only a 750-HR lamp, so it wouldn't last long running dusk to dawn. Running 8 hours per night, a 750-HR lamp would only last 94 nights in service (it would die three-quarters through the 93rd night if the math worked out perfectly). If anything, the lamp would die early from vibration on the long unsupported filament. If I were to put this into service I'd probably use a 130V bulb so it lasts way longer. I'd try to find something close to 1000L too so it would be original (so probably a 130v 150W incandescent).

No you gotta use clear lamps in these (so no CFLs, no LEDs) or else the optics get messed up.

Very nice! Sadly the original 1000 lumen bulbs do not seem to be made anymore. I know at work we can no longer get them. Luckily I found a few cases in our basement. They're sylvania 105w 1000 lumen bulbs.

@streetlight98 :
How about a clear filament LED lamp?

@ gmercury: Do you actually have quite a few incandescents left in service at work? Or did you get to keep the cases you found for your collection?

@ xmaslightguy: I'd totally use a ~1000L clear LED filament lamp if I could find one with a A21 or A23 envelope and all-glass. Would look awesome.

We only have a small handful 25-30 at most still on our system. They are already in the works of being scheduled for replacement though. I was able to keep the lamps I found due to that and they are using 100w long life lamps for the time being.

Sweet that you were able to keep them. How many hours are the 105W 1000L street light lamps rated for? Are you guys still installing HPS replacements or have you started using or only use LEDs now? Around here the utility still installs HPS (and only HPS). Anything that's not HPS becomes HPS upon needing maintenance. Some cities want LEDs so they have purchased ownership of the utility-owned lights and with their own resources and fixtures, gone LED. That way the utility company doesn't have to bother with the lights anymore. The city owns the lights, so there is no more rental fee, just the kWh fee. National Grid (the utility) requires municipal-owned lights on wood poles to have an inline fuse between the mounting arm and the triplex feed to allow the fixture to be disconnected when serviced. The city I live in uses 10A inline cartridge fuses. Seems a little high for one light but I suppose it's more for a means of disconnect than it is for overload protection, since the utility-owned lights have no fusing at all.

I want to say they are rated for 12,000 hours if I remember reading to box correctly.

We are upgrading to LED now, there is one municipality that still wants HPS but otherwise if it's defective it is upgradedd to LED. Be it MV or HPS. Our set up is very similar but we maintain both utility owned and municipality owned lights. Generally lights on our poles are not fused, however generally all underground fed lights are fused. We use a 15A inline fuse though.

Speaking of incandescent street lights, West Penn Power was the last power company in my area that maintained their incandescent street lights until the late 80's when they weren't able to procure replacement fixtures or parts anymore. They're all gone now. They removed incandescent street lighting from their tariff not too long ago. West Penn Power still maintains their mercury vapor and high pressure sodium street lights, but if a mercury vapor street light goes bad, it gets replaced with a high pressure sodium street light. Many municipalities in their service area have had their lighting changed to LED's over the past 2 years and if the high pressure sodium street lights are less than 20 years old, participating municipalities have to pay for the remaining value of the lights.

12000 hours isn't too bad for incandescent! For 1000L at 105W though they'd better last awhile.

Around here they would relamp incandescents until the 90s but if the fixtures were damaged or whatnot they were either replaced with MV or HPS.

When towns want to go LED here, they have to pay $1 per light fixture (regardless of age) and that $1 gives the town/city ownership of the light and mounting arm (or in the case of metal poles, everything past the splice in the manhole beside the pole, but metal pole lights I assume would cost more than the $1 wood pole lights). The idea behind the $1 was the original cost of the lights less depreciation. Once the lights are installed, the utility here places no value on the light. Just like driving a brand new car off the lot. It could be two days old but it's not worth anything anymore (in the case of cars the value is semi-retained but for lights, they utility company treats a month-old light like a 50 year old light).

It's weird, I just looked at the packing for the lamps and the sleeves state 1120 lumens but the bulb its self is labeled 1000 lumens. I was right about the 12000 hours. I'll post a couple pictures. If you would like a couple I'm sure I could spare some lol. 4 cases is more than I'll need in a lifetime.

We still relamp our remaining incandescents, but as I originally stated, their days are numbered.

Duquesne Light used to have incandescent street lights as well, but they stopped servicing them in the late 70's and by 1988, there were only a few incandescent street lights left in their system. They still install and maintain high pressure sodium street lights, they still have hundreds of mercury vapor street lights in service too, but they aren't serviced anymore, they upgrade them to high pressure sodium street lights when they go out, even if it's just a burned out bulb.

One of my gumballs, which is used dusk to dawn has a 800L LED filament with a socket extension. Looks pretty good at night and I don't need something super bright anyway.

Toronto had incandescent streetlights in parts of the downtown core until the mid 90s, when they replaced them all with metal halide. They used new MH gumballs for the replacements so the lights still looked like the incandescents they replaced. Curiously a lone incandescent gumball survived to 2016 when it was replaced with a MH gumball.

Toronto still uses high pressure sodium outside of the downtown area but the outer suburbs went to LED in 2013-2017.

Here in Southern California, Southern California Edison still actively installs and maintains HPS, MH and LPS. There are incs and MVs also but very few of them. They have now started changing to LED, but only when cities request the changeout. In Northern and Central California, PG&E is almost done with the HPS to LED changeout, and recently they stopped maintaining HPS. Any city that did not opt in, the utility will replace the HPS lights with LED when they burn out. The city of Los Angeles is now about 80% LED, but there are many remaining MV, HPS and incandescent lights around.
