What is this product

The EiKO LED12WT5HE/34/840-G9D is a 3-foot T5 LED tube made for ballast bypass retrofits. It replaces a 21W T5 fluorescent lamp with a 12W LED lamp while maintaining strong light output at 1740 lumens. It uses a G5 base and runs on 120-277VAC once the ballast is removed or bypassed per fixture wiring requirements.

TL;DR: Who is this for

- Electricians and maintenance teams converting linear fluorescent fixtures to LED by removing or bypassing the ballast

- Facility managers who want lower energy use and fewer lamp changes in dry indoor spaces

- Contractors updating offices, retail back-of-house, corridors, or utility rooms that use 3 ft T5 lamps

Institutional Fit

- Strong fit for multi-site maintenance because it is a common voltage range (120-277VAC) after ballast bypass

- 50,000 hour rated life supports fewer relamps and lower maintenance cycles

- Neutral 4000K CCT works well for general task areas and commercial interiors

- UL listing helps with procurement and safety documentation

Top Highlights

- Ballast bypass T5 LED retrofit lamp for 3 ft fixtures

- 12W power draw with 1740 lumens output (145 lm/W efficacy)

- 4000K neutral white with 80+ CRI

- 120-277VAC operating voltage (after ballast bypass)

- 50,000 hour rated life

- Non-dimmable

- Dry location rated

Technical Specifications

Regulatory Compliance

- UL listed: confirm the marking on the lamp and follow fixture and local electrical code requirements for ballast bypass conversions

- Use only in dry locations as specified

- Non-dimmable: do not use on dimming controls unless the fixture and lamp documentation explicitly allow it

Durability and Lifecycle

- 50,000 hour rated life supports fewer relamps compared to fluorescent

- Ballast bypass removes a common failure point (the ballast), which can reduce future service calls

- Operating temperature range supports typical indoor commercial environments

Procurement notes

- Retrofit type: this is ballast bypass. Confirm your fixture is being rewired for direct line voltage and that your team follows the required wiring method for the lamp and fixture

- Size check: 3 ft T5 with 34 in max overall length. Confirm lamp length and socket spacing in your fixture before ordering

- Voltage check: supports 120-277VAC after bypass, useful for mixed building voltages

- Light planning: 4000K is neutral white for general work areas. If you are matching an existing space, confirm the CCT used across the room

- Control planning: non-dimmable. If you need dimming, select a dimmable LED T5 option instead

FAQ

Is this a ballast compatible lamp?
No. This is a ballast bypass T5 LED lamp. The fixture must be wired for direct line voltage per the required method.

What fluorescent does it replace?
It is listed as an equivalent replacement for a 21W fluorescent T5.

What voltage does it run on?
120-277VAC after ballast bypass.

Is it dimmable?
No, it is non-dimmable.

What color temperature is it?
4000K (neutral white).

Where can it be used?
Dry indoor locations.

How do I confirm fit?
Check that your fixture uses a G5 base T5 lamp and that the lamp length matches a 3 ft T5 (max overall length 34 in).
