TUBU-A Round LED Tubular Light
TUBU-A series · round tube · 20W/40W/60W · IP65
The TUBU-A is a round LED tubular light for damp rooms, sealing its driver and SMD2835 board inside an IP65 Ø76mm tube that stands up to water jets, dust and corrosion while delivering 3000-9000lm at 150lm/W.
This cylindrical vapor tube suits wet rooms, corridors and wash areas alike: a 120° frosted beam spreads even light without glare, the round profile sheds water where flat battens trap grime, and surface, suspension or wall mounting fits new and retrofit sites.
- 20/40/60W, 3000/6000/9000lm, 150lm/w efficacy
- IP65 waterproof & dust-proof, anti-corrosion sealed tube
- 120° beam, frosted cover, CRI >80, SMD2835
- Surface/suspension/wall mount, 220-240V AC

Sealed, versatile and fast to install
Sealed round body: water, dust and corrosion stop at the seal line
Waterproof, Dustproof and Anti-Corrosion
Washdowns and damp air kill ordinary indoor tubes within seasons. The TUBU-A answers with a fully sealed Ø76mm round body rated IP65: silicone rings at both ends plus a PG waterproof cable gland keep jets, dust and corrosive vapor away from the driver and LED board.
- Waterproof — water jets from any direction cannot get in
- Dustproof — sealed tube keeps lenses clean in dusty plants
- Anti-corrosion — internal aluminum heatsink inside PC tube stands damp chemistry
One tube, three mounts — surface, suspension and wall arms
Surface, Suspension and Wall Mounting
Corridors, wash areas and retrofit halls never share one fixing. The TUBU-A ships with stainless steel clips for surface mounting plus a suspension kit, and an optional plastic buckle with wall bracket aims the Ø76mm tube from side walls over aisles and benches.
- Stainless clips — fast surface fix to damp ceilings
- Suspension wires — even rows over open wash halls
- Wall bracket — side light over aisles without blocking equipment
Twist, wire, close — minutes per fitting with no special tools
Tool-Free Wiring in Minutes
Long corridor rows live or die by install speed. The TUBU-A end cap twists off by hand: push the 3-core cable through the PG gland, tighten the terminals, twist the cap back on — no special tools, minutes per fitting, so a whole wash-area row goes up in one visit.
- Twist-off end cap — opens by hand for wiring and maintenance
- PG waterproof gland — cable entry stays IP65 after connection
- 220-240V AC direct — wires straight into existing circuits

Why TUBU-A for Damp Rooms
150lm/W round tube for wet sites
A round IP65 tube for rooms that kill ordinary indoor battens — water jets, dust and daily washdowns. The Ø76mm cylinder sheds water and dust where flat battens trap grime on top, and sealed ends keep washdown water off the driver and LED board. A 150lm/W SMD2835 engine delivers 3000/6000/9000lm through a 120° frosted cover that spreads even light without glare, and one family covers 3000K warm corridors, 4000K work areas and 6000K inspection benches. For high racking aisles above 6m where a diffuse tube can no longer hold floor lux, step up to the FORT-A linear high bay for oily factories — and for compact bathrooms and stairwells that need a wall or ceiling fitting with sensor backup, the AQUA-D waterproof bulkhead for bathrooms covers those rooms.
Three checks before you order a round tube
- IP65 means washdown jets, not pressure washers — this tube takes end-of-shift hose-downs in kitchens, car parks and wash areas; lines cleaned with high-pressure jets need IP66 or higher, so match the rating to the cleaning method before you order.
- PC takes knocks, not chemistry — the polycarbonate cover survives the odd tool strike, yet ammonia air and strong alkaline detergents haze it over time; rooms washed daily with aggressive cleaners should take a PMMA-cover tube instead, and no tube should ever be wiped with solvents or ketones.
- Size it against the fluorescent it replaces — roughly speaking, 20W stands in for twin 18W T8 tubes, 40W matches twin 36W at about half the system power, and 60W covers what twin 58W did; count fittings from the old layout, then halve the energy bill.

|---|---|---|---|
 | TUBU-A | Round tube Ø76mm, 20/40/60W | Damp rooms and wash areas — 150lm/W round tube; sheds water and dust where flat battens trap grime on top, twist-off end cap for fast corridor rows. |
 | FORT-A | Linear high bay, tempered glass | Oily factories and warehouses — 50°×100° lens throws lumens down the aisle where a diffuse tube would wash walls and fall off. |
 | AQUA-D | Round bulkhead, sensor options | Bathrooms, corridors and balconies — microwave sensor plus emergency backup where a plain tube cannot switch itself. |

FAQ
Round-tube answers for damp and wash areas
Sealed round tube with silicone rings and PG gland holds IP65 — the Ø76mm cylindrical body sheds water and dust where flat battens trap grime on top, the frosted PC cover resists corrosion, and the sealed ends survive daily washdowns. Do not submerge it; IP65 covers jets, not immersion.
Three mounts cover retrofit and new builds — stainless steel clips for surface fixing, suspension wires for open halls, and the optional plastic buckle with wall bracket for side walls. Mounting accessories ship in the box with step-by-step video guidance.
Twist-off end cap with PG waterproof gland opens without tools — strip the 3-core cable, push it through the gland, tighten the terminals and twist the cap back on. The whole connection takes minutes per fitting, which is what makes long corridor rows affordable to install.
20W for low damp rooms, 40W for corridors, 60W for wide halls — take the 20W tube (3000lm, Ø76×L600) for bathrooms and compact wet rooms; the 40W tube (6000lm, Ø76×L1200) for corridors and wash areas; the 60W tube (9000lm, Ø76×L1500) for wide damp halls at 3-5m. All three run at 150lm/W with PF over 0.95.
Rated 50000 hours on SMD2835 chips — years of corridor and wash-area service — backed by a 5-year warranty covering driver and LED board under normal use.
