This LED flashlight bulbs were designed by Deshun in 2004. A high efficiency LED driver is built in each LED bulb, which enables the bulb to be used in a wide  

range voltages of 1V~3V. LED flashlight bulbs will work well and won’t burn out. The 1V~3V LED flashlight bulb can quickly convert any C and D, 1-2 cells  

flashlight bulb of PR style flange or E10 base from standard incandescent to a bright white long lasting LED flashlight bulb.

 Special Features of Dosoe LED flashlight bulbs:

1. High-efficient Constant Currant LED Driver

 High-efficient constant currant LED driver is built in each bulb to make it work under a certain stable current even when the  using voltage varies, thus enabling the bulb to keep working with low battery power and extending its lifespan.

 2.   Auto Temperature Control Function

 The LED driver can also automatically control the bulb’s temperature into a safe level when the temperature of a lighting-up bulb is getting high. This Auto Temperature Control Function protects the bulb from burning out and makes it work longer.

 3.  Reverse Polarity Protecting

The polarity of Dosoe LED flashlight bulb is protected, so the bulb won’t burn out even if the power supply is connected reversely.

With another feature of Shock-Resistant, Dosoe LED torch bulbs are super-efficient, energy saving, and eco-friendly. It’s definitely the best choice for your flashlight!
