Portable LED work light

01

Match light output to runtime

Ansmann's WL1500R Pocket Flex datasheet lists performance by mode: 100% gives 1,600 lm, 3,000 lux and 50 m range for 3.5 hours; 50% gives 800 lm for 7.5 hours; 25% gives 380 lm for 16 hours; and the spot beam on its flexible 30 cm arm gives 350 lm and 100 m range for 12 hours. Its main light is 6000 K and auxiliary 7000 K with CRI Ra >80, from 15 W + 3 W COB LEDs. [1]

The LED's work 0300165 rechargeable work light lists 700 lm from 10 W (efficacy 70), cool white 6000 K, CRI 80, a 120° symmetric beam, flicker-free and not dimmable; its datasheet states four hours of runtime in the description and 3 h in the battery table. [2]

Editorial calculation: Ansmann's 16.28 Wh pack over 3.5 h at 100% averages about 4.7 W drawn from the battery; LED's work's 32.56 Wh over 3–4 h averages about 8–11 W, consistent with its 10 W rating. [1] [2]

At the larger end, Streamlight lists its Portable Scene Light III, a tripod-mounted area light for construction, maintenance and first-responder use, at 10,000 lm, 121,000 cd and 696 m beam distance for 2 hours on high; 5,000 lm, 61,000 cd and 494 m for 4 hours on medium; and 2,500 lm, 38,000 cd and 390 m for 8 hours on low, from one SL-P6 battery, with unlimited run time on supplied AC or DC cords. It is rated IPX7 (1 m for 30 minutes) with the battery fitted but IPX4 without it, has a gasket-sealed high-impact thermoplastic head of 3.4 kg on a 6.2 kg steel and aluminium tripod (9.7 kg in total) extending from about 1.2 to 2.6 m, and quotes a 50,000-hour LED life. [4] Editorial calculation: halving output doubles run time across the three modes (2, 4, 8 h), so the battery delivers about the same lumen-hours in each; 121,000 cd gives about 538 lux at 15 m on axis (121,000 ÷ 15²), well above the 323 lux that OSHA's 30 foot-candle row works out to. [4] [3]

Give the supplier the lumens needed per mode and runtime per charge, beam (flood or spot), CCT and CRI, battery type, capacity and voltage, charging method and time, IP and IK rating while working and charging, mounting (hook, magnet, stand), temperature range, weight and certifications.

02

Check protection, battery and charging

Ansmann lists IP65 and IK08 protection but notes IP65 applies only in battery operation and IP20 while charging; the 3.7 V 4,400 mAh, 16.28 Wh Li-ion pack charges in about 3.5 hours by USB-C; the housing is aluminium, nylon and TPR with hanging hooks and holding magnets; it operates at −10 to 40 °C and should be stored at 0 to 30 °C. [1]

LED's work lists IP65, −20 to 40 °C, an aluminium housing with tempered glass, safety class III, a 7 V Li-ion battery of 4,400 mAh and 32.56 Wh, 5 hours charging through a DC 5.5 mm adapter, 500 charging cycles, 162 × 265 × 144 mm and 890 g net. [2]

Editorial calculation: 3.7 V × 4.4 Ah = 16.28 Wh, matching Ansmann's label; 32.56 Wh ÷ 4.4 Ah = 7.4 V nominal, matching LED's work's 7.4 V input. [1] [2]

Compare what suppliers offer

The supplier linked to this page lists portable LED work lights; its card links to the page reviewed.

Ask any supplier for lumens and runtime per mode measured to a stated method, battery cell type, capacity and Wh, charge time and charger, cycle life, IP and IK ratings during use and charging, beam and CRI, temperature range, weight and transport certification for lithium batteries.

04

Check the light level the work area legally needs

US OSHA's construction rule 1926.56 requires construction areas, ramps, runways, corridors, offices, shops and storage areas to be lit to at least the Table D-3 minimums while work is in progress. The table sets 3 foot-candles for concrete placement, excavation and waste areas, access ways, loading platforms, refueling and field maintenance areas; 5 foot-candles for general construction area lighting, indoor warehouses, corridors and exitways, and tunnels, shafts and general underground work, rising to 10 foot-candles at tunnel and shaft headings during drilling, mucking and scaling; 10 foot-candles for construction plant and shops such as mechanical and electrical equipment rooms and carpenter shops; and 30 foot-candles for first aid stations, infirmaries and offices. For areas or operations the table does not cover, OSHA refers users to American National Standard A11.1-1965, R1970, Practice for Industrial Lighting. [3]

Editorial calculation: at 1 foot-candle = 10.764 lux, the Table D-3 minimums of 3, 5, 10 and 30 foot-candles equal about 32, 54, 108 and 323 lux. A work light's lux figure is measured at one distance and beam setting, so ask the supplier for the lux at your working distance, in each mode, and check it against the minimum for the area. [3]

06

Fill the specification fields with values for your order

A portable LED light quotation needs values for your users. The table explains each field, gives published values where a reviewed source states them, and says what to obtain from the supplier.
