Lights of America Shoplight Ballast

Lights of America Shoplight Ballast

Click to view full size image

The newer design "shoplight" ballast seems to be a lot better than the old. I bought one of these fixtures a) because they only cost about $7 new and b) the ballast runs both T8 & T12 lamps. I don't know how this is done, as the more expensive Advance T8 ballasts will not do this, and the lamp current is quite different between 48" T8 & T12 lamps. The startup is quite interesting on this fixture too - the ends glow a little and then the arc seems to move from the ballast end to the other end until fully lit (about one second). The ballast is almost totally silent in operation.

Just noticed that "Luminaires" is spelled incorrectly on the ballast....hmmm....it might have been assembled in the USA but nobody caught that...

I'm lampin...

Sounds like it has a starting system that is easier on the lamps than normal if the ends glow it means it is not starting them cold-cathode style which means hopefully longer life

I have seen this kind of starting before...sought after by me... can't find which brand does that.... . Another type is the striation glow start...seems to have been extinct.

Either LOA made this themselves or they outsourced it from another company but just get a fixture like this and take the ballast out you could probably have some fun with it

@imj: The ballast in my bathroom fixture does this at start-up...sort of preheats before it strikes. It's a GE/Magnetek 2 lamp rapid start Triad that will run one or two lamps. The part# is B240R120RH and is labeled for 40w T12 but I've been using T8 for over a year and it seems to work fine. I don't know if they still make them.

The common ones are just preheat and strike.....pretty boring I had a 20w T8 electronic(now dead) from Hongkong that did the striation glow with preheat at the same time! That's cool

Is the striation glow where the ends glow and parts of the tube glow before starting?

Yes the ends glow and the tube glows dimly with moving rings and slowly brightens up. The whole process takes about 2s.

It makes you kinda wonder if it's really made in USA. Aside from he misspelled word, the last sentence in the caution is not very coherent.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.

My guess is still China, but the grammar slipped by an illiterate American: "If Lamp [s]are not working, unplugged (!) and plug in power cord". And why is the first letter of every word capitalized?

@ imj: That "striation glow start" you are talking about is a common effect on U.S. rapid start 40w magnetic ballasts. Most of mine do that. I haven't seen it on any electronic ballasts though. The cathodes are heated at the same time as the primary voltage (which is much lower than on instant start ballasts) is applied. From what I've observed, electronic ballasts that are not instant-start types are usually program-start, where there is a delay (no light, or just the ends) while the cathodes are heated & then the lamp ignites completely in a second or two and the cathode heat is shut off.

I'm lampin...

@TudorWhiz: (Yes I am a disturber)See there are better fixtures out there than the LOA ones!(He has the older version of these LOA Lifelites in his garage workshop and says they're good fixtures...)

I'll take a good wraparound or old industrial preheat anyday over a LOA fixture!

Hey I am telling ya....those preheat magnetic with electronic starters LOA...works great for me......and I have 3 of those in this house been in this house for over 5 years with ONLY ONE lightbulb change (that's only one tube needed to be change!) and don't forget....the fixture in the garage are the ALTO bulbs...but not the other 2...both of the ALTO bulbs still BRIGHT and working.......so you disturber!!! It is very disturbing when you say they ain't good fixtures when EVEN Rick who hates today's rapid start lights said those LOA lights (the older ones) are "DECENT LIGHTS".............They are good as long as you use 40 watt bulbs ONLY NOT the 34 or 25!!!

Yes there's one at the theatre I used to work at that has been very good. Only been through one relamp in 6 years and runs 12hr a day, no problems!!!

But I've also seen a good amount of the preheat electronic starter LOA fixtures where the electronic starter fails in a way where the capacitor becomes parallel with the lamp, raising the crest factor to the lamp enough to quickly kill it and any other lamps installed in the bad side.

Sometimes this failure mode is caused by someone putting a F34 in one of these, which will NOT work in these LOA fixtures.

Other times the F40 installed will die but keep rectifying because the electrode is still intact but out of emissive material. This sometimes causes the failure mode above with the starter.

Having said all that, I have some American Fluorescent T5 fixtures with Radionic ballasts that work the same way i.e. preheat with electronic starter. Lamp life on these is decent and no problems with the starter! They are F8T5 and F13T5 fixtures...

I shall not disturb often

I accidentally put on F34T12 in a similar of these the cap and starter got screwed up and that side never worked again

Decent fixtures? Well with the older ones from the 80s and 90s if you are very very careful and use ONLY 40 watt fluorescent tubes they MIGHT last for a while. They were very fragile fixtures that can be damaged even by a voltage dip. I have seen some which will operate only one fluorescent tube because they had been damaged by such dips. The current T-8/T-12 fixtures, I haven't seen enough in use so it's hard to tell if they're durable. They do seem to be better built tho.

Well as least I know a good fixture from an OK one...

Or an excellent fixture from a good one...

How about LOA fixture = B rapid start = A old preheat = A+

I agree with you Jace! Thats why I said MOST spiral CFL's. The Commercial Electric ones last their rated life most of the time and are made by TCP or Technical Consumer Products. The Home Depot now carries n.vision instead, but still made by TCP, so same good quality for spiral CFL's...

I bought 6 Commercial Electric CFL's...23 watts 5500k for lamps around the house and one died within a few weeks but the others have been doing well for almost a year so far.

The Commerical Electric CFLs seem to last a while although the ones I used in the bathroom blackened badly after a year of use.

It lives! I've revived this fixture; I thought I broke one of the lampholders when trying a T12 lamp in it but it sorta fixed itself. Put two new T8 GE Ecolux lamps in and then flush mounted it sideways in my garage. I love the way the lamps turn on - the bottom one starts at one end and then brightens to the other end, and then the top tube comes on. These fixtures do seem a bit better made in fact than the older magnetic LOA fixtures but time will tell....the "Engrish" on the ballast cover isn't a good sign...

I'm lampin...

I believe that's correct about the older LOA shoplites having a preheat with electronic starter. And there's actually two ballast circuits one for each lamp. And yes when the starters got wrecked and how sad it was to see perfectly good new lamps quickly burning up in commercial areas where the owner should have bought proper commercial fixtures in the first place.

My sister's new-old house has in the basement a very old looking LOA shoplite with black plastic instead of white and a pull chain in the "ballast". It looked in good shape and the lamps were not being burned up.

Me thinks these combo T8/T12 shoplite ballasts are nothing special, and are just normal T8 ballasts. Just like people have observed, T12 lamps are dim due to the lamp current of a T8 is about half of a T12. You can accomplish the same thing with any old T8 ballast by putting in a T12, it will be dim.

I want to add that the electronic starter was not typical of an electronic starter that you would find as a replacement for your normal glow bottle starters. The LOA starter works by switching the electrodes with 10 - 20 hz pulses, instead of a normal slow open/closed state. A lamp failure would often spell death for the starter if the dead lamp was not replaced quickly. The lamp rectified while the starter is continually activated while the lamp is rectifying. So a failed lamp would appear be rectifying and the electrodes were glowing at the same time. You can easily imagine what happens to the starter after continuously 10-20hz pulsing all day long with a dead lamp.... *poof*. Then that would spell death for the next lamp because that wrecked starter causes high crest factor.
