Philips TL100W/01 Bulb

PHILIPS 100-watt, 6-foot “Long Length” High-Output UVB-Narrowband (311 nm peak)

This is the original Philips 6-foot UVB-Narrowband bulb. It measures 70.25″ far-end to far-end and fits most pre-2003 North American UVB-Narrowband devices, and continues to be used in European devices. Similar to TL100W/01‑FS72 bulbs except longer – check part numbers before ordering. Bulb is 1/2″ too long to be interchangeable with FS72 length bulbs as used in most North American devices built after 2003 (use TL100W/01‑FS72 instead).

Fits SolRx: 1000‑Series (pre-2003 devices – production lots R and down).
Also Fits: Pre-2003 North American devices (Daavlin, NBC, Ultralite), European devices
