▲1. Explosion-proof execution standards comply with national standards GB/T3836.1-2021 and GB/T3836.4-2021.
▲2. Explosion-proof rating not less than: Ex ib IIC T4 Gb; Ex ib IIIC T130°C Db (CCC certification provided).
▲3. Rated voltage ≥3.7V, rated power: ≥3W, battery capacity ≥1800mAh.
4. Working time: Features three light modes—working light, high-intensity light, and strobe. High-intensity light working time should be ≥5h, working light working time should be ≥10h. 5. The lamp features a four-segment battery level display for clear visibility of remaining charge; adopts Type-C charging design, supporting universal USB interface charging available in the market; the lamp head can be adjusted by 45 degrees to meet lighting needs at different angles.
▲6. Under ambient temperature conditions of 20±5℃, the device shall withstand drops from a height of 1m ≥4 times without failure of its explosion-proof type.
▲7. At test voltage ≥500V and application time ≥60S, there shall be no flashover or breakdown between the intrinsically safe circuit and the enclosure, and leakage current ≤0.1mA.
▲8. Protection rating: ≥IP66.
▲9. When the battery pack is short-circuited until fully discharged, there shall be no obvious traces of electrolyte, and the battery structure shall remain undamaged.
10. Provide inspection reports issued by third-party testing centers and explosion-proof certificates; items marked with ▲ must be substantiated in the inspection report.
High-intensity Floodlight
▲1. Product performance complies with the requirements of standard GB30734-2014 "Firefighter Lighting Lamps".
▲2. Explosion-proof standards comply with national standards GB/T3836.1-2021, GB/T3836.2-2021, GB/T3836.4-2021, and GB/T3836.31-2021. Explosion-proof mark not less than: Ex db ia IICT6 Gb; Ex ia tb IIIC T80℃ Db (CCC certification provided).
3. Features multiple light modes including high-intensity, working, low-intensity, strobe, and SOS.
4. Rated voltage: ≥DC11.1V, rated capacity: ≥4400mAh, rated power: ≥3×3W, dimensions: ≤69×165mm (diameter × length), weight: ≤1kg.
▲5. Working time: High-intensity ≥8h, working light ≥16h (substantiated in fire inspection report).
▲6. Protection rating: ≥IP66/IP68 (2m/2h). (Reflected on explosion-proof certificate)
▲7. Illuminance at center of light spot at 5m distance: High-intensity average value ≥1030lx, minimum value ≥740lx; Low-intensity average value ≥500lx, minimum value ≥380lx.
8. User-friendly battery level indication and low-voltage warning function allow checking battery status at any time; when 90% of battery is used, the lamp switch changes from green to red, and the lamp automatically flashes 15 times. High-intensity mode lasts 15 minutes, working light mode lasts 30 minutes, prompting recharging.
▲9. Spacing between intrinsically safe circuits and non-intrinsically safe circuits ≤2.7mm; spacing between circuits and grounding or isolated metal parts ≤2.5mm.
▲10. Transparent component (tempered glass) shall show no damage that invalidates the equipment's explosion-proof type after impact test with object weight 1Kg and steel punch diameter 25mm.
▲11. Provide inspection reports issued by third-party testing agencies recognized by the state with CMA and CNAS marks; content marked with ▲ must be substantiated in the inspection report.
