BS-YJ003
Bestshow
When the grid goes dark, this light keeps working. The BS-YJ003 uses SMD 2835 LEDs (Epistar or Sanan chip) rated at 100 lm/W, ensuring uniform brightness without glare. The integrated indicator light shows charging and operation status, while its dual-mode switch allows you to choose between strong light for task work and soft light for energy saving.
Its Li-battery pack recharges rapidly, offering stable discharge for up to half a day. With a wide voltage tolerance (AC 85–265 V), it adapts to regional power standards across markets. The compact body and optional wall-mount or hanging hook make it equally suitable for factories, workshops, or temporary field setups.

Advanced SMD 2835 LEDs delivering > 100 lm/W luminous efficacy.
Balanced illumination with no flicker — ideal for workspaces and inspection zones.
Li-ion battery ensures long backup time (6–12 h) and over 500 charge cycles.
Integrated protection circuit prevents overcharge and thermal damage.
Strong mode for full brightness task lighting.
Weak mode for ambient use and extended runtime.
Wall-mount, hook, or handheld configuration.
Lightweight structure (< 1 kg) enhances portability for mobile operations.
Certified under CE / RoHS / SAA / SASO for international distribution.
Flame-retardant ABS body meets LVD and EMC standards.
| Environment | Typical Use |
|---|---|
| Residential | Home backup lighting, hallways, staircases |
| Commercial | Retail stores, showrooms, offices, receptions |
| Industrial | Warehouses, factories, maintenance areas |
| Outdoor Use | Camping, night markets, field repairs, adventure tours |
| Public Facilities | Schools, hospitals, malls, parking areas |
Each application benefits from consistent brightness and easy portability — ensuring productivity and safety when power reliability is uncertain.
Built for practical beauty: a matte white ABS shell with smooth curves that stay cool to the touch even under prolonged use. The light emits a clean, stable beam that cuts through darkness without harsh glare. Subtle status indicators show charging and power conditions — no guessing. The tactile switch clicks softly, giving a sense of control and readiness every time.
Imagine walking through a warehouse during an outage or fixing equipment outdoors at night — the BS-YJ003 turns that interruption into confidence.
