Hi Edd,
Yes, this is the Radio Shack small hand held flourescent light. I bought all I could find in my area, especially at such a cheap price of $ 1.98 each. Any help getting this 3 volt unit to work using 4 volts will be greatly appreciated. Again thank you Edd for your help.

I would like to know if the solar panel I have will charge the battery I have. Here are the specs for the solar panel and battery.<p>Solar Module<p>Voltage: Open Circuit 8.0 Amperage: Short Circuit 0.156 VMP: 6.7 Volts IMP: 0.145 AMPS Watts: 1.0<p> Battery<p>12 Volts 17 Watts Floating Charge Voltage...

Hi Edd,
The wires were connected properly. The light was on and the transistor started smoking. The markings on the transistor are C2328A and below that Y-932. Thanks for your help.

How can I operate a flourscent light built to run off of 2 AA batteries, using a 4 volt battery? This is just a little project I am working on using a 4 volt rechargable battery. I have a small solar panel that came with the battery for recharging. Thanks.

Hi Russ,
If you mean how much current does it draw, I am guessing 1 amp or even lower. I am not real sure at this moment. I can measure it when I get home and let you know tonight.

I am trying to figure out a way to operate a floursent light that uses 2 AA batteries to run off of a 4 volt battery. I hooked up the 4 volt battery to the light and the only transistor on the board began to smoke. I looked all over the web for information on the transistor, but did not find much. W...

I am trying to reduce a 4 volt battery to a 3 volt source. I have used a 1 ohm 5 watt resistor, which drops the voltage to 2.9 volts, but the resistor is eating up the battreies current. I think the resistor was using up around 1 amp of current. Can someone help me design a voltage regulator circuit...

I have a 4 volt 4.6 amp hour lead acid battery that I want to power 3 or 4 super bright white Leds. Each of the Leds is listed at 20 ma. The reverse voltage is 5v and the forward voltage is 4 v max. I thought about putting them in series, but need help calculating the current limiting resistors. Tha...

Can someone tell me how much voltage is required to power the boards that run the small flourescent tubes used to backlight a laptop screen? Thank you.

The flourescent light I am using orginally operates on two AA batteries ( 3 volts ). I am wanting to power it with the 4 volt battery I have. Thus I need to reduce the voltage by 1 volt.

I have a 4 volt 4.6 amp hour lead acid battery that I want to use to power a 3 volt flourescent light. The question I have is, what is the best way to drop from 4 volts to 3 volts and not use up the current I want going to the light? I would like to retain as much of the 4.6 amps from the battery so...
