LED Tube Lights for T8 & T12 Fluorescent Replacement
Upgrade 4-foot fluorescent fixtures with the HyLite OptiMax LED T8 Tube Light. The current 12W/15W/18W model combines selectable wattage, five selectable color temperatures, up to 2,300 lumens and Type B AC-direct installation in one commercial retrofit lamp.
One 4-Foot LED Tube.
Multiple Wattages and Color Temperatures.
The current OptiMax model HL-GT8-4B-12-18W-3065K is designed to replace T8 and T12 fluorescent lamps in compatible commercial fixtures after the fluorescent ballast is properly bypassed or removed.
OptiMax 12W / 15W / 18W Type B LED T8 Tube
Instead of stocking separate tube lights for different output levels and color temperatures, the OptiMax combines three wattage settings and five CCT settings in one lamp. This can simplify purchasing and give facility teams more flexibility when lighting requirements vary from room to room.
| Setting | Light Output | Efficacy |
|---|---|---|
| 12W | 1,620 lumens | 135 LPW |
| 15W | 1,900 lumens | 127 LPW |
| 18W | 2,300 lumens | 128 LPW |
Input voltage: 100–277VAC, 50/60Hz
Fluorescent equivalent: Up to 44W fluorescent
Installation: Type B AC Direct / ballast bypass
Five Selectable Color Temperatures in One Tube Light
Select 3000K, 3500K, 4000K, 5000K or 6500K to match the appearance and task requirements of the space. One tube can cover warm, neutral, daylight and high-CCT applications without stocking five separate lamps.

OptiMax Tube: Type B AC Direct
The 12W/15W/18W product is Type B AC Direct. The fluorescent ballast is bypassed or removed and approved line voltage is supplied to the LED tube according to the current wiring instructions.
Single- or Double-Ended Power
The current Type B model supports single-ended power input from either side and double-ended input configurations. Follow the current HyLite wiring diagram for the exact installation.
Qualified Installation Required
Ballast-bypass retrofit work involves line voltage. Power must be disconnected and installation should be completed by a qualified electrician or lighting technician following current instructions and applicable requirements.

Why Replace T8 and T12 Fluorescent Tubes with LED?
Fluorescent systems depend on both lamps and ballasts, creating two components that can eventually require service. A properly selected Type B LED retrofit removes the ballast from the operating system and supplies the approved line voltage directly to the LED tube. This can reduce future ballast-related maintenance while preserving the existing fixture housing.
Selectable wattage also makes it easier to tune light output after installation, while selectable CCT can help facilities standardize tube inventory across offices, warehouses, healthcare spaces, utility areas and other commercial environments.

LED Tube Light Retrofit FAQ
Can the OptiMax LED tube replace both T8 and T12 fluorescent tubes?
The current HyLite specification states that the OptiMax 4-foot LED T8 tube is designed to replace T8 and T12 fluorescent tube lights in new or existing compatible fixtures. Fixture dimensions, voltage and wiring still need to be confirmed before installation.
Is the current 12W/15W/18W OptiMax tube ballast compatible?
The current specification sheet linked from this page identifies model HL-GT8-4B-12-18W-3065K as Type B AC Direct only, which requires the fluorescent ballast to be bypassed or removed. Do not assume ballast compatibility unless the exact lamp model and current ballast compatibility documentation support it.
Can the tube be wired single-ended or double-ended?
Yes. The current Type B specification supports single-ended power input from either side and double-ended power input. Follow the current wiring diagram and installation instructions for the selected configuration.
How many color temperatures are available?
The current selectable model provides 3000K, 3500K, 4000K, 5000K and 6500K in one tube.
Is the current OptiMax Type B tube dimmable?
No. The current Type B specification states that the lamp is not dimmable and should not be used with dimmers.
Can OptiMax tube lights be used with motion controls and sensors?
The current HyLite specification lists compatibility with motion controls and sensors. The complete fixture and control configuration should still be reviewed for the application.
Planning a T8 or T12 Fluorescent-to-LED Retrofit?
Send HyLite the existing fluorescent lamp number, ballast model, fixture voltage, fixture photos, number of lamps per fixture and project quantity. We can help identify the current OptiMax product and installation approach that should be reviewed for your facility.
