Emergency light bulbs

This page is the outage brief: bulbs whose job begins when the grid stops. Emergency bulbs matter where outages are a daily planning fact — they keep stairs safe, shops open and homes calm without generators or rewiring. The catalogue's emergency family holds the two rechargeable bulbs plus lantern formats; the bulbs are documented here, the lanterns on their own page.

The two emergency bulb formats

A70 E27 rechargeable emergency bulb — the programme bulb. Power options of 7 W, 9 W, 12 W and 15 W let a buyer grade rooms by importance; emergency time options of 1–4 hours come from an 1800 mAh battery; the bulb is 6000 K cold white, CRI 80, 270° beam, packed 1 per box and 100 per carton. Rechargeable LED emergency bulb — the endurance bulb. A fixed format with 8–10 hours of emergency lighting, 6000 K, 270° beam and 90–100 lm/W flux, for the rooms that must never go dark.

Emergency runtimes in the family	1–4 h options (A70); 8–10 h (long-runtime model)

Input	AC 220 V (±10%)
Colour temperature	6000 K
Beam angle	270°
Family companions	Rechargeable camping lantern (15–40 W options, >10 h, SOS mode)

How emergency bulbs are bought

Programmes are usually built in layers. Layer one is life-safety and continuity: stairs, entries, bathrooms and one room per dwelling get the 8–10 hour bulb. Layer two is comfort: living spaces take the A70 at a power matched to the room, with the 1–4 hour option set to the local outage pattern — there is no value in paying for 4 hours of battery where outages run 45 minutes. Layer three is mobility: a lantern per household or stall covers everything the fixed bulbs cannot reach.

What to confirm on an emergency programme

Local voltage: the records are written around AC 220 V (±10%); state your market voltage in the enquiry.
Socket standard: E27 is the recorded base; B22 markets should confirm availability per model.
The runtime option set per model, and carton configuration for retail distribution.

Do emergency bulbs work in enclosed fittings?

They are standard A70/A-format bulbs; follow the fitting's own limits. Heat shortens battery life, so open or vented fittings are preferred.

How are they different from rechargeable bulbs generally?

Same products, different brief: this page selects and layers them for outage duty; the rechargeable bulbs page documents the models themselves.

Testing and maintaining backup bulbs

A backup bulb that has never been tested is a hope, not a system. The maintenance routine is trivial and worth printing on the carton: once a month, switch off at the breaker for five minutes and confirm every backup bulb in the building carries its room. Batteries age with heat and time, so bulbs in enclosed fittings should be the first checked and the first rotated to open fittings. For facility programmes — schools, clinics, small hotels — keep a small overstock: the failure mode of this category is not the bulb dying, it is the bulb being borrowed for a normal socket and never returned. These habits cost nothing and are the difference between an outage plan and an outage anecdote.

Emergency bulbs and building practice

In unreliable-grid markets, backup bulbs are quietly becoming a building standard rather than a gadget: landlords fit them in stairwells between tenancies, small hotels specify them for corridors, and clinics treat them as part of the outage plan alongside the generator. The pattern matters for programme buyers because standards create steady demand — the replacement and extension purchases follow the installed base, and the installed base follows whoever supplied the first fit-out. Programmes aimed at this layer should lead with the endurance format for the never-dark points and treat the configurable A70 as the volume line behind it.
