Products using high count of ~ 100mW max LEDs tend to run then at about 65mW for 2 lumens @ 20mA per. A review mentions it runs for 3 minutes upon motion activation.
120 x 20mA = 2.4A. Suppose it uses 2400mAH NiMH batteries (just a random guess) then that gives it an hour runtime which is quite a few activations at 3 min. per, IF the solar cell manages to put that much charge into the battery.
I'm suggesting that if your light comes on more often than that, you might as well just have a hardwired, constant on light which uses a bit more power but the initial purchase price is lower to offset that.
^ They're handy for other purposes too, like if I was fumbling to get a key in a locked door, fetching a newspaper, checking a mailbox, or an indication when wildlife comes around looking to snack in the garden or ransack a trash bag.

Thank you!
