Motorola Lumi-kon magnetic F40 / F25 ballast

Motorola Lumi-kon magnetic F40 / F25 ballast

Click to view full size image

Scored a duo of wraplights (C&M and York Montreal) this ballast was in the C&M wrap. The york has a Philips 0.80a kool koil

Never seen a magnetic motorola ballast. To bad its average current.

Testing shows it works but has that classic warm up 60hz flicker with hum. Especially with F34s. Conclusion is this ballast is a HPF version of a shoplight ballast

I have a similar Lumi-kon ballast in a shoplight somewhere, except mine is a proper HPF ballast with a slightly higher ballast current than yours.

Old lighting is, and will always be, the best lighting.

Is yours rated for F25s? Ive never seen an F40 ballast include them. I think the capacitor in this is tired as it started up with that flickery hum with F40s and F34s

Oh, only 0.63 for the 40 watt lamps. That sounds like the issue here... not really a crappy capacitor. Really low at 0.51 for 34 watt lamps too.
I'm surprised Motorola made magnetic ballasts though, of any kind. That's crazy.
And seeing how bad shoplight ballasts act, not sure if this fits in that category. Especially since this is Rapid Start. This is still probably a crappy
ballast though.

When it starts cold the lamps have a 60hz flicker with rings and the ballast hums louder but this goes away after several minutes. I think thats a sign the cap is worn out. Itll happen no matter what lamps i put in. I dont really mind that as it gives me a nostalgic feeling dont think the 0.63a rating is the cause

My 87% power factor Rapid Start ballast does this as well when lamps are cold, but with mine the hertz flicker
never really goes away. To me, that's more of a sign of a bad capacitor... but then again, that ballast has only 0.68 amps.
60hz flicker during cold start up on HPF Rapid Start ballasts is normal. I'm use to seeing this a lot, especially with
the two lamp HPF Universal Rapid Start ballasts. Now... easy to see striations with F40T12 lamps... THAT'S not normal. lol... usually
you'll see that with 34 watt lamps, not 40 lol

You may be correct. I always assumed that once the cap warmed up after several minutes of runtime it would become closer to normal spec so the 60hz flicker stops. Another reason of my thinking was because i have ballasts with similar specs that dont have 60hz flicker. This is why i like old stuff, theres mystery involved and something new to figure out.

The rings were mostly with the 34s. Ive never really seen F25T12 lamps, what lamp size is that?

I wonder if they meant to specify F40T12 25W lamps.

@Lightingguy1994, yep I've seen it too... I've had/have some magnetic HPF R.S ballasts that don't have the 60hz flicker at all.
Then again, I've noticed that a lot of HPF R.S magnetic ballasts have different kind of capacitors, so that may be why.
And I agree... there's always a mystery with the old stuff. Good mystery... not bad, unlike LED. lol
F25T12 lamps, from what I know, operate the same as F40T12 lamps when used with most, if not all magnetic HPF R.S ballasts.

Oh i forgot about those, yeah i have some of them. I hadnt thought of those in this case because those 25w lamps are for LPF shoplight ballasts and this being HPF i figured it was asking for some sort of real 25w bulb.

@Lightingguy1994, honestly, it asking for F25T12 lamps gets me scratching my head as well. There's even a drop in amps for
those lamps. Do you have any F25T12 lamps you could try on this ballast?
I'm not sure I've ever seen a HPF R.S ballast listing F25T12 lamps on the label.
And then also, I wonder how EOL lamps act on this ballast? Of course I bet they just dim flicker, maybe flash with occasional
orange swirling at the bad end but probably not much flash.
EOL lamps on my 87% Power Factor ballast don't flash much, if at all. Not much orange flashing/swirling with that ballast either
when lamps reach EOL while fully lit.

I have the 4 foot F25s but they are packed away but when i can i will test it out for sure. The different amp rating also confused me. Im wondering if theres a lamp that's between the F20 and F30. ill check the site that i usually buy from and see if they have it

According to my prefered suppliers site. The F25T12 is a preheat lamp and comes in 28" , 30" and 33" and has an average life of around 7500 hours.

This leads me to think that this ballast may also be fine with F20T12s

@Lightingguy1994, dude I'm so confused. haha... I've never heard of either one of those lengths for any fluorescent lamp.
But since the ballast indicates that it runs F40 and F34/35, which are all 4 footers, I can only assume they mean the 4 foot version. lol
If that be the case, I'm not sure I'd run F20T12 lamps on this ballast for a long period of time.

I added this one to my list of "shoplight ballasts". Lightingguy1994, you win first High Power Factor!

edit: This is first 'HPF version of a shoplight ballast' which caught my attention, but far and long away from first uploaded on Lighting-Gallery.net.

(F20T12 lamp filaments are different from intended Rapid Start filaments. Driven by this ballast, F20T12 lamps might not last as long as rated life. FC6T9 (20W) and FC8T9 (22 W) lamps have arc similar to F20T12, and are available with Rapid Start filaments.)

I noticed that the MagneTek 439-L-TC-P is a lot like this ballast, only the MagneTek one has a slightly lower ballast current than the LumiKon.

Try a single f32t8 connected between the red and blue wires.

High Intensity, you are right. I spent hours today, went down a rabbit hole, finding additional utility/shoplight/worklight L.B.F. ballasts. This is not first HPF shoplight ballast on Lighting-Gallery.net, not by far. It was first to catch my attention.

I must clarify, I meant that I've never seen another magnetic HPF motorola ballast on gallary before.

Musictomyeyes, that's a neat list you have I'm grateful to have made it on there

I have one of these, but it doesn't say 'Motorola' on it.
I also have a LPF version.

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