I bought one of these at WM and another at HF. Amazon had a much better deal for 4 on a flash deal. They work great almost anywhere you need light for a short period, especially where you don't have an electrical line and want a conventional light switch. I have several of the other type where you have to push for on and off and that's a pain if you have your hands full. This positive conventional switch is really great and it works fine on the lower voltage rechargebles (nominal 1.2v instead of 1.5v). I might post back after a run test to see how long they run on fully charged batteries.
UPDATE 10/15/2018
Tested these on 3 different sets of batteries in 3 of the lights from this set--- the original Ninghai Hengjjiu non rechargeable batteries supplied with the product, 1100 mah rechargeable Bonais available from AMZ and 750 mah Eneloops. All the rechargeables where charged fully with a Powerex MH-C9000 so their battery capacity could be determined. This was not a test of battery capacity, but the numbers turned out to be somewhat telling and are listed after the results posted below. This test is also not reflective of the way these lights would normally be used, but I did have an interest in continuous use if I had use them to perform a task in the shed that could last an hour or more.
Any one of them could last an hour or even longer. The Ninghai alkaline batteries supplied with the unit(s) performed best, way out lasting the rechargeables from Bonai and Eneloop. The photo shows the relative brightness after 21 hours for the Ninghai alkalines and Bonai sets (left and center respectively) and 16 hours (light that's upside down on right) for the Eneloops. Although only rated at 750 mah, the Eneloops put on a pretty good showing after 16 hours.
The 2 dimmer lights with rechargeables would still provide enough light to do a quick search in a dark closet if hand held. Not a practical search though. If turned off and left to recover, the light would be much brighter for a number of seconds..
My only concern with alkaline NON rechargeables is leakage. If these lights are placed in an environment where they are seldom used, eventual leakage could create a mess. That's not a fault of the light. Even given the lesser performance with the rechargeables, I'm inclined to use them to avoid the leakage issue. I can only reaffirm the 5 star rating and recommend they be used with low self discharge rechargeable batteries.
Pros:
--Even a better bargain if you can catch a flash deal
--Fairly long lasting in continuous duty
--Even longer lasting bright light in intermittent service
--Work well on rechargeable batteries and recommended where lights are infrequently attended to
--Familiar conventional light switch
--Versatile mounting options
Cons:
--Magnetic mount not going to be the most stable
--Might have to supply tape mount with something more durable like UVB tape
Additional notes: Capacity in MAh at completion of charge:
--Bonai 1100- 932, 956, 1000, 995
--Eneloop 750-- 682, 733, 746, 705
Supplied batteries- Ninghai Henjjiu 1.5v Long Life Alkaline; capacity not determined. Note: the Powerex probably could have clocked the milliamps dishcharged over time by setting it to discharge mode, but those batteries would not have been able to be used after discharge cycle.
