One Philips, and One Sylvania PL-L 18w, Separate PL-L HPF Rapid Start Ballasts

One Philips, and One Sylvania PL-L 18w, Separate PL-L HPF Rapid Start Ballasts

Click to view full size image

Obviously the Sylvania 18w lamp is longer in length than the Philips 18w lamp.
Both on separate R.S ballasts. Both also bright! These lamps typically instant start,
but sometimes they'll act as Rapid Start. Idk why

What color temp is the Philips lamp? Also, mine tend to instant start on cold startups, but rapid start on warm startups.

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

I dont think there is such difference between normal lamps of different manufacturers. There might be some special version lamp in there or a 24W lamp

There's literally no notable difference in color temperature between the two of these lamps. Although the sylvania is longer
in length, both are 18w lamps...
The Sylvania: FT18DL/830/RS/ECO 18W 2G11 3000K
The Philips: Philips PL-L 18W/830/4P 18W 2G11 3000K

My ballast says it's for 10.5 inch lamps. Does the Sylvania one measure to 10.5 inches?

@fluorescent05, I have no idea. I'll have to get a tape measure to see sometime. Then again I will say this... for an 18w
lamp, that Philips lamp really does look kinda small. AND... it flickers. It's noticeable flickering, but mainly if you look at
it directly. The Sylvania one flickers only at the ends. Both lamps start up perfectly fine though.

Does your Philips lamp make a weird cricket sound?

That's a good question, because yes it does. But only a little bit. Not like crazy loud but it's definitely loud enough
to point it out. Seems as if it flickers more when it's fully warmed up.

End blackening is also on the increase. Actually, significant end blackening has been taking place on two of my 36w PL-L lamps.
Both on the same ends, and on the same sides of the bulbs as well... tough to explain. I plan on getting it on video.
Those lamps have been used previously though, but fast end blackening like what I'm seeing is kinda concerning. All electrode filaments
are heating as they should, so I don't know what the deal is. EOL will be happening soon though. Could be interesting since OCV
is 450 with those two lamp PL-L Rapid Start ballasts. Maybe interesting. lol

Before I got my 2x18 PL-L magnetic ballast, I operated my lamps on a 2x20 trigger start ballast and the ends blackened a bit.

That's not too surprising, since filament heating on Trigger Start ballasts is typically higher than
with Rapid Start ballasts. The filament heating with these PL-L ballasts is definitely not as high as Trigger Start.
Another thing I forgot to mention... the Philips PL-L 36w lamps also flicker noticeably. The ballasts I'm using for those 36w
lamps are rated for 2 PL-L 40w lamps. I wonder if that's why I'm seeing so much end blackening occurring so quickly?
I'm also wondering if the flicker I see from them is because of that as well. The PL-L 36w lamps don't flicker as
violently as the Philips PL-L 18 watt lamp though.

Not like an actual cricket of course. (That'd be weird) More like a slight buzz. All 8 of my PL-L lamps buzz,
but the PL-L 18w Philips lamp is the loudest of them all. None of them are extremely loud though, just noticeable buzzing.
