if bright about a 40 or 60w old fashioned bulb has 2 power settings they seem to be about 15-20 percent duller but 55% more run time
it has a carabiners type loop
a magnetic in the carabiners base
a hanging loop and a great selection off angles
i have some figures but may have confused a 2.5ah and a 2ah but will update with further tests lol
a 9 year old 1.3ah battery on low power lasted a few mins short off 6 hrs [17.00-22.54hrs]
a 2.5ah 1 year old on low 10h 14m [13.30-23.44 this may have been the 2ah]

same battery on full 6h 22m [10.40-1700 again may be the 2ah but more likely the 2.5]
the worklight is indeed expensive at £35-40 but well worth the money as its compact and light
