Description
AS-E303 Series — 5W Dual-Function LED Emergency Downlight
The AS-E303S / E303C / E303R is a 2-in-1 luminaire that works as a comfortable everyday downlight — The AS-E303 is a CE-certified LED emergency downlight for the European and export markets, built as a 2-in-1 battery backup downlight: it works as a comfortable everyday ceiling light — and takes over as emergency escape-route lighting the moment the power fails. Its wide AC85–265V input supports global voltage, and the built-in LiFePO₄ battery provides 3 hours of emergency lighting backup.. Powered by a built-in LiFePO₄ battery with 3-hour backup, it combines stepless dimming, 8-level tunable white (2700K–6500K) and 433 MHz wireless control in one compact, IP66-rated fixture. One light for daily lighting, safety and smart control.

Indicators & Controls at a Glance
LED status indicator
- Green — mains connected, battery fully charged.
- Red — charging in progress (turns green when full, approx. 16 h; max. 24 h).
- Orange — fault alert: rapid flash = battery fault, slow flash = light-source fault.
- Blue — 433 MHz signal: blinks once every 20 s in standby, once per received command; solid 5 s = sleep mode.
On-fixture test button
- Long press — increase brightness; long press again to decrease, in a loop.
- Short press — cycle through the 8 color-temperature levels.
- 1 s press — simulate a power failure (emergency mode); press twice consecutively in emergency mode to switch it off.
- 5 s press — start simulated monthly inspection; 8 s press — simulated annual inspection.
- Double press in standby — activate emergency output.
AS-WRC01 remote
- Power ON/OFF (mains mode) and Emergency ON/OFF — independently controlled.
- M / TEST / Y keys — trigger monthly test, power-failure simulation and annual test remotely.
- Warm / 4000K / Cool keys plus brightness up/down — full lighting tuning from the wall.
Where It Fits
- Offices & meeting rooms — tunable white for focus and comfort, silent emergency backup.
- Corridors & stairwells — 125° round lens or 30°×75° wall-beam lens for even escape-route lighting.
- Hotels & retail — surface-mounted versions need no ceiling cut-out, ideal for retrofits.
- Damp & semi-outdoor areas — IP66 handles basement passages, covered walkways and utility rooms.
- Smart homes — 433 MHz control with automatic self-test, no hub required.
Warranty & Maintenance
- 5-year warranty on the luminaire; 3-year warranty on the battery pack.
- Battery rated for 500 charge cycles at 80% capacity — replacement recommended every 3 years.
- Charging: 3.65V / 300 mA (max. 350 mA), with over-charge protection at 3.65 ± 0.01V and over-discharge protection at 2.2 ± 0.1V.
- Operating range: 0°C–45°C at continuous full load (−10°C–55°C short-term).

Emergency Lighting Compliance — EN 1838
EN 1838:2013 (Lighting applications — Emergency lighting) defines the minimum lighting requirements for emergency situations within the EU. It covers three functions: ① Escape-route lighting — minimum average 1 lx along the escape path, max-to-min ratio ≤ 10:1; ② Open-area (anti-panic) lighting — minimum average 0.5 lx across the area; ③ High-risk task-area lighting — at least 10% of normal illumination and not less than 15 lx. Our emergency luminaires are designed to meet these illumination levels. The applicable duration (typically 1 h or 3 h) and the notified-body certification for your project are confirmed per model and order — request the declaration of conformity / test report for the exact model you specify.

Questions About This Product
What is the difference between continuous and non-continuous mode on the AS-E303 emergency downlight?
The AS-E303 offers two operating modes. Continuous mode keeps the luminaire active as a normal light at all times; non-continuous mode runs the emergency function only when needed. The mode is set by your wiring method and can be controlled via the AS-WRC01 433 MHz remote.
How long does the AS-E303 emergency battery last and how long does it take to charge?
The AS-E303 uses a 3.2V LiFePO₄ battery that delivers 3 hours (180 minutes) of 5W emergency lighting with a transfer time of ≤0.5 seconds. A full charge takes about 16 hours from empty (guaranteed within 24 hours); the indicator turns from red to green when charged.
Can one AS-WRC01 remote control multiple AS-E303 lights?
Yes. The AS-WRC01 433 MHz remote controls multiple AS-E303S/C/R luminaires within range: 30 meters in open areas, 15 meters recommended indoors with line of sight. No Wi-Fi or hub is required.
Is the AS-E303 suitable for damp areas and corridors?
Yes. The AS-E303 is rated IP66 — fully dust-tight and protected against water jets — making it suitable for corridors, stairwells, basement passages and covered semi-outdoor areas. Its interchangeable lenses offer a 125° round beam or a 30°×75° rectangular beam for escape routes.
What happens if the AS-E303 battery or LED fails?
The AS-E303 self-reports faults via its LED indicator: rapid orange flashing indicates a battery fault, slow orange flashing indicates a light-source fault. The luminaire carries a 5-year warranty and the battery pack a 3-year warranty (replacement recommended every 3 years, rated 500 cycles at 80% capacity).
Is the AS-E303 suitable for emergency lighting in commercial buildings?
Yes. The AS-E303 is a self-contained emergency downlight with 3-hour LiFePO₄ battery backup, ≤0.5 s transfer time, and built-in monthly/annual self-test simulation for maintenance verification. It is certified to LVD, EMC and RoHS standards. As with all emergency lighting, please confirm the required placement and duration with your local fire and building regulations.
