Overview
A 4-foot direct-wire T8 tube for 120V circuits that you can dim from a standard forward-phase (TRIAC) wall dimmer. It replaces an F32T8 at 14.5 watts, puts out 1,900 lumens of neutral 4000K light, and uses a coated glass body that holds together if it is dropped. The ballast comes out and the sockets are fed line voltage directly.
Features
- 14.5W draw replaces a 32W F32T8 fluorescent lamp
- 1,900 lumens at 4000K, CRI above 83
- Dims on forward-phase (TRIAC) dimmers on 120V circuits
- Ballast bypass: no ballast to buy or replace later
- Coated shatter-resistant glass, frosted to hide individual LEDs
- Instant on, no mercury, 50,000-hour rated life (L70)

Compatibility
Remove the existing fluorescent ballast and wire 120V line voltage to non-shunted G13 lampholders as shown on the spec sheet. Not for 277V circuits. For dimming, use a forward-phase (TRIAC) dimmer rated for LED loads together with the dimming accessory listed on the spec sheet.
Frequently Asked Questions
Q: Do I need to remove the ballast?
A: Yes. This tube runs on line voltage, so the existing fluorescent ballast is removed and the sockets are wired directly. Check the spec sheet for single-ended or double-ended wiring and use the lampholders it calls for.
Q: What kind of dimmer does it need?
A: It is rated for TRIAC dimming. Use a dimmer listed for LED loads, and check the spec sheet for any accessory the dimming method requires.
Q: Why is there a minimum order quantity?
A: This item ships in Keystone's sealed carton of 20, which protects it in transit, so it is sold in multiples of 20.
