COB Promier LED Wireless Night Light With Switch

Only problem I've had with this night light switch is the "tape" on the back. It keeps falling off the wall. Light is very bright, though.

GREAT

Despite the name of this product ( COB LED Wireless Night Light With Switch ), it should NOT be used as a Night Light. This is because:1. It is way too bright. The light output is rated as '200 lumens' which is roughly equivalent to that from a 25-Watt incandescent bulb.2. It eats batteries like there's no tomorrow! A set of 3x AAA batteries (either alkaline or rechargeable NiMH) can only operate the light for around 2 hours.[Power Consumption]Just like most cheaply made LED lamps and flashlights, this product does not contain any power regulation circuit at all. The LED module is driven directly by the three AAA batteries, so the LED current is at the mercy of the battery voltage and internal resistance.As can be seen in the “Power Consumption vs. Battery Voltage” chart I uploaded, the light consumes around 2-3 watts when powered by three AAA batteries. This is consistent with the advertised ‘200 lumens’ of light output. But as the battery voltage drops, the power (and hence light output) also falls off rapidly.[Bottom Line]This LED ‘Night Light’ is not suitable for use as a night light. On the other hand, it is somewhat useful in places where you only need illumination for a few minutes, such as in the closet or near the thermostat (in case the LCD screen is too dim to read). You just have to remember to turn off the light promptly after use.[Other Remark]'COB' is not the brand name of this product. It actually stands for 'Chip-on-Board', which means multiple LED chips are assembled on top of a heat-conducting board.

COB LED Wireless Night Light With Switch Use Duracell Rechargeable Ni-MH AAA 1000mAh Batteries and you'll get about an hour of ON time!!!

Simple, effective, bright. The two vertical bars light up when you turn on the switch. Batteries inside. That's it!
