Wonderful design: emergency LED bulb built-in battery can be removed when the flashlight

When you are in power, will you try to find a flashlight? Recently, a built-in lithium battery price of $15 (about 91 yuan) LED bulbs to solve this problem. The name of the Ascella bulb can continue to light when the power through the internal battery, to achieve the effect of emergency lights. Interestingly, the Ascella can also be removed from the lamp holder and used as a flashlight.

Ascella bulb has a mode selector switch. Only in switching to emergency mode, Ascella can continue to shine when the power outage. Ascella built-in battery life up to 3 hours. However, when the battery power supply, Ascella bulb brightness will decline. When the Ascella back to the base, the internal battery can be filled within 3-4 hours. In addition, the official said the Ascella bulb life of 3 hours per day at a frequency of up to 18 years.

Ascella bulbs are not that good. In the actual test, we found that the brightness of the Ascella is only equivalent to the 30W ordinary bulb, although the official said its brightness can reach 150 lumens. In addition, when charging, even if the Ascella installed on the base, it can not be properly lit. Do not know if this is not a design defect.

The idea of the Ascella bulb is quite new. However, the brightness and functional defects in the actual use of this light greatly reduced.
