Description
what is LED Double Tube Fixture
The LED Double Tube Fixture is a twin-T8 style linear luminaire for tough indoor and semi-outdoor applications. It combines high efficiency SMD2835 LEDs with an aluminum tube heat sink and PC base plus transparent UV resistant diffuser for even light output and long life. 2×9W, 2×18W and 2×22W options with 100-120 lm/W system efficacy — strong lumen output and energy savings for commercial spaces.
LED Double Tube Fixture Detail
Bridge wiring in fixture
no need to consider power-in direction
Bridge wiring inside the fixture provides a polarity-agnostic power path so installers don’t have to worry about tube orientation during installation. This simplifies wiring for long runs, reduces commissioning errors and speeds up installation for big projects.
Smart inverter for one tube in emergency mode
A compact smart inverter dedicated to one tube switches to battery power when mains fails, maintaining regulated light output in emergency mode. Intelligent control prioritizes efficient conversion and battery protection to prolong runtime and ensure predictable emergency performance.
Specifying fixtures with smart inverter avoids separate emergency drivers, simplifies wiring and ensures critical escape routes are lit in fault conditions.
Special housing for battery — quick replace design
A dedicated battery compartment with clip-fix or tool-free access allows for fast battery replacement without removing the whole fixture. This design minimizes maintenance downtime, perfect for big industrial lighting applications. It ensures battery replacement operations are quick, safe and traceable.
Contractors get standardized battery modules and clear access points; facility operators get lower lifetime maintenance costs and easier compliance with emergency system tests.
T8 LED tube with full PC cover & aluminum heatsink
A full polycarbonate (PC) cover with aluminum heatsink tube combines impact resistance and thermal management: PC diffuser resists UV aging and aluminum core draws heat away from the LED chip for longer life.
Anti-UV Transparent Diffuser
Durable PC Base
Metal Mounting Bracket

Frequently Asked Questions
What wattage and lumen output can I expect from the LED Double Tube Fixture and how many do I need?
- Wattages: 2×9W, 2×18W, 2×22W.
- Efficacy: 100–120 lm/W. To calculate lumen output, multiply fixture wattage by efficacy range. Example (2×18W = 36W): 36W × 100–120 lm/W ≈ 3,600–4,320 lumens per fixture.
- How many to install: determine target lux for the space (e.g., 100–200 lux for general storage, 300+ lux for task zones), measure area (m²), then divide total lumens required by lumens per fixture. For help sizing a run or achieving uniformity in corridors or tunnels, COMLED’s technical team can provide layout guidance and recommended spacing.
Can this fixture be used in wet or dusty environments such as parking garages or tunnels?
Yes. The IP65 rating means dust-proof and low-pressure water jets, so it’s suitable for covered parking, tunnels and similar semi-exposed areas. IK08 impact resistance adds mechanical durability against knocks or stone chips. The transparent PC diffuser has anti-UV treatment to preserve transmission over time. For fully exposed outdoor installations or areas with chemicals or pressurized washdown, check with COMLED to confirm the right variant and mounting method.
What does “single-end power-in” mean and are there installation risks?
“Single-end power-in” means the power supply is at one end of the tube assembly, not both ends. The advantage is easier retrofitting where the power is already at one end; it’s also faster installation. But correct wiring is crucial: follow local electrical code and the fixture wiring diagram. For on-site wiring recommendations, compatible linkable wiring schemes or to request a version with different wiring, contact COMLED’s technical/after-sales support for drawings and guidance.
Is there an emergency option and what is the warranty?
An emergency version is available to meet egress and safety lighting requirements; please request emergency-spec details when ordering (COMLED can provide the emergency runtime and battery option that suits your project). The standard non-emergency product warranty is 3 years. For emergency variants, battery and driver warranties may follow manufacturer terms — confirm battery life and warranty specifics when ordering.
How does this simplify bulk purchasing and installation in large projects?
- Standard sizes & terminals: T8 footprint and 5.0mm push-in terminals means faster installation and less electrician time.
- Mounting & durability: stainless/PC clips and IP65/IK08 rating means less rework and replacement.
- Factory customization: linkable runs and emergency versions means you can standardize across a site.
- Support: COMLED can provide technical documentation and sales support to help with order quantities, packaging and delivery terms for large orders—ideal for contractors and facilities teams who want predictable lead times and consistent performance.
