This 85-watt high output T12 tube replaces the Sylvania F72T12/DSGN50/HO. HO lamps operate at higher current than standard tubes, delivering significantly more lumens from the same length. Features an R17D recessed double contact base - note that HO tubes require compatible HO ballasts.
With 5100 lumens of output, this lamp delivers serious brightness - enough to illuminate large spaces or compensate for high ceilings. The 5000K daylight color temperature produces light that feels energizing and alert - close to natural midday sunlight. With an exceptional 92 CRI, colors appear vibrant and true to life. Skin tones look natural and color-matching tasks become more reliable.
