The SYLSTAR COB Rechargeable Work Light is a cordless LED floodlight with a carry handle, folding feet and a 360-degree rotating head. It comes third in this round-up of ten work lights, at £55.99, and carries a 4.3-out-of-5 rating from 1,431 Amazon customers. The star breakdown listed with it runs 68 five-star, 13 four-star, six three-star, five two-star and eight one-star.

This is the listing where the wattage headline and the wattage specification part company. The title says 100W and the Wattage field repeats 100 watts, while the Maximum Compatible Wattage field on the same page reads 50 watts. The brightness figure holds together better in the copy: 7,000 lumens appears in the title and again in the Light Output Maximum field. The battery is where it splits again — the title claims a 10,800mAh pack, the specifications list 6 C batteries required and included, and the Battery Description field says Lithium-Ion, which is two different answers to the same question. Everything on this page is taken from the Amazon listing; we have not tested the light ourselves.
