Sylvania lifeline HO Devils eye

Sylvania lifeline HO Devils eye

This lamp is still holding strong even though it has tons of hours on it. I noticed this clear triangle shaped window appeared so I can see the filament perfectly. I have keep a eye on this lamp as it keeps a eye on me. As soon as the sock appears I will retire it. It's in my new industrials I just got last week.

Why not let it go EoL?

The more you hate the LED movement, the stronger it becomes.

It will cook the new ballast I just put in there. I may put on a electronic ballast just to see a show

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

Very typical blackening of a Sylvania HO lamp.

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

The electron bombardment looks strong enough to move the phosphor coating

Pretty, please no more Chinese failure.

Yeah if this lamp goes, the ballast will probably get hot, but I'm pretty sure it won't harm the ballast. That Automatic Resetting Thermal Protection
won't kick into gear unlike with Slimline ballasts lol... then again I guess it depends on what ballast we're talking here. But I've never
really heard of an EOL lamp causing harm to a HPF Rapid Start ballast of any kind lol

The main problem with EOL lamps in this situation is the stress on the internal series capacitor. When a lamp starts strobing (with the orange swirls) there are large voltage spikes across the cap. I've had the older oil-filled ones short out from this while the newer dry-film type become eroded, causing reduced lamp current for the next batch of lamps.

... I'm taking notes... I may have witnessed short outs myself with the F40 GE Bonus Line cold temp versions. The starting side
normally lights up dimly first, then the non starting side, before both lamps fully brighten. I remember hearing a faint zap inside
the ballast... after that, the starting side would no longer dimly light, unless I shocked it back into working, by putting in a lamp
on the non starting side, followed by twisting it out. When I did that, the starting side would be dimly lit again, but then the faint
*zap* would happen inside the ballast again, and the dim light on the starting side would go out again... does anyone know what I'm talking
about? I know, horrible description... but I'm really trying to paint the picture here. This happened to more than one 2 lamp cold temp
ballast, including one Universal version I had... but several of the GE Bonus Line cold temp ballasts I had, did this.

Many of the older 2x40w ballasts had oil filled three terminal capacitors. I believe one terminal is common, one is starting (very low farad value) and the other for both lamps fully lit. The newer ones probably have a separate small film cap along with the larger film cap.

I've seen a couple different ballasts lose the starting side for whatever reason...likely an open connection inside; also, the starting side can short out causing only one lamp to light full brightness over-driven and overheat ballast.

It's not worth the risk to me anymore I lost a universal f48t12 vho ballast in less than a year because of a black sock on both ends it was never used old stock ballast from 1971 It exploded with smoke and oil all over the inside of fixture. I forgot to shut it off during a 90 degree day last summer I'm sure that didn't help. For now I will put black socks in a designated fixture with a highoutput electronic ballast to eol the lamp.
