SOX-E 18W starting glow

SOX-E 18W starting glow

Finally got a good color balance to properly capture the unique penning mixture glow. Supposedly the 18W has 1.5% argon versus 1% in the larger lamps. This one does look more pink than my 55W. Running on a Fulham Workhorse 2 instant start HF fluorescent ballast. It starts the lamp easily, but seems to underdrive it, as the ballast only pulls about 130mA out of the wall at 119V.

Know what you mean, my 180watt SOX looked way out on camera, the true colour is reflected in the table.

Nice shot! That does appear to capture the starting color of these smaller lamps.

Another thing about the pinkish color on these, is when they are new, they are more argon rich. As they age and the glass absorbs some of the argon, their startup will shift to more of a red color.

Yes. The borate glass of SOX lamp, absorb small argon gas as the lamps ages. A problem might arise, when all of the argon was consumed and the lamp wouldn't strike.

Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Yes, the Argon/Neon gas are small enough to get trapped in the Borosilicate glass crystal lattice at the inside surface.

Pretty, please no more Chinese failure.

rjluna2: the glass type that the LPS tube made, is borate (Which resistant to sodium), not borosilicate (Which corroded by sodium). And only the argon lost from the argon-neon penning mixture through the borate glass. The neon remains inside.
