DX 30-LED Rechargeable Wide Area Illumination Light (AC 100~240V)

If you can't see the ruler the dimensions are 70mm wide X 240mm long, 45mm high
Switch Low Off High
Runtime is quoted as 4 hours on high 8 hours on Low, all LEDs are lit on both Hi & Low. It appears to have two small SLA batteries, batteries measure 4.6 volts charged. LEDs draw 750mA on high, 260mA on Low, 750 / 30 gives us 25mA per LED on high and 260 / 30 8.7mA on Low, so it looks like the LEDs aren't overdriven and should have a long and happy life. The unit comes with a very thin power lead with a European style plug, also comes with a plug adapter (unfortunately mine came supplied with an American adapter).
The lights have an emergency on feature. If left plugged in on the High setting they will light when the power fails.
The output is cool white. The construction is typical Chinese adequate but not top quality, still a good buy for $16.23. I bought these as room lights for power failures and I'm sure they'll be perfect for there designed application.
Just thinking about the current draw figures you would think runtime on Low should be three times the runtime on High not double.
