Squeaky clean grooves.

Squeaky clean grooves.

Click to view full size image

These things were absolutely grody when I first saved them... Mouse crap, hair, dust, spray paint, rust stains and unknown substances.... They took hours to clean.. I used a combination of pinesol, Windex, rubbing alcohol, and axe body wash.

I only cleaned the functional tubes as I didn't feel like wasting time on the dead ones today. Maybe one day I'll clean the dead ones but for now they'll be stashed in a closet somewhere.

What is the manufacturing date of the second tube from the left? That is the only tube that hasn't been dated yet...

Nice job!

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

They look great now

If it were me, I wouldn't even waste time cleaning the dead ones, since I'd simply be getting rid of them.

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

I figure one day I may hand them off to someone like vintage fluorescent who appreciates dead tubes...

To be fair one of the dead ones is quite neat looking with its greened out phosphors

These made perfect street lights until the mercury vapor overtook them. Short lived but bright as heck.

Why did mercury over take them? The lumens per watt rating is pretty good on these.

I think they were more expensive than mercury vapor lights.

I think its because of a combination of things. These dont last as long as HID so require relamping more often. At EOL the fixtures are probably left that way for months so the ballasts die too and its more pricy for the bulbs and ballasts as well as the time the crews spend on each light. Especially in fixtures that have 2-3 pairs of bulbs with each set of 2 in series

Mercury vapor on the other hand lasts longer and doesnt kill the ballast if left EOL for extended time. Also it's much faster and easier for the crew to relamp a single screw-in style bulb saving costs in labour.

I have those 6 lamp PowerGroove fixtures and they have two ballasts that run three lamps each in series. One loose connection or dead tube will make that set of three not work.

Preheat Fluorescents forever!

You also must factor in that fluorescent lamps of any type don't particularly like cold weather and the ballasts don't appreciate the heat either. 2 things that EVERY outdoor lighting fixture has to deal with on a regular basis.

Powergroove/VHO are good for -20F.

Yes tolerance to cold temps is a must, especially here in the north where we can get -40 in the winter. The HPS streetlight on my street that normally cycles regularly does not cycle when its that cold

T10 jacketed works the balls under 20 degrees

T12/ t17 there's a reason they made heavy magnetic ballasts

I believe HO will also start at -20F too as long as you're not using the energy saver ones.

I know they will start under -20 degrees but the question is will it become full brightness? Especially when windy. HO seems to stirate and flicker the whole time when real cold vho gets a dim spot in the middle. Powergrooves dont get to proper temp and can be a little dim especially when has good hours on them. T10j has no issues

I've as a test fired up and ran F96T12-HO 's in the negative mid-teens, and yes, they start fine but won't reach full brightness (especially if there is any bit of a breeze). Haven't tried VHO, but I suspect results would be the same...
Maybe I'll have to try it with a F48 VHO sometime (but I personally won't risk subjecting a PG to that sort of abuse)

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

I don't remember where but I read somewhere that the fluorescent streetlights were known for heat related ballast failures and low light output in cold weather.

I will say however that I saw a parking lot lit with 4 lamp , 6' fluorescent fixtures last spring and I was surprised at how even and bright the light was.

I should go visit one of the parking lots here that still have these big fluorescent streetlights in use. Bit curious now to see what fixtures and lamps they actually have in them. Yeah all of the fluorescent installs I've seen at night seem to be pretty even and bright.
