Grundig FR200 LED lightbulb
I just purchased a Grundig FR200G radio, but it came this a regular type
filament bulb. I have seen the Eton Corp. site advertising a FR200 model radio equipped with a LED lightbulb. Has anyone got the model with the LED lightbulb? I'm just wondering if the LED bulb is interchangeable with the filament bulb. I didn't see the LED bulb available on the Eton Corp. FR200 parts list. |

Call Eton and ask them...it is a new model.

Yes. While it isn't as bright as a incandescent, it will run
much longer on a single cranking charge. Are you sure it is a filament bulb and not a LED? My FR200G has a set of 2/3AA NiMH that are charged by the hand crank. It will also take 3?AA cells. and accept +4.5V into an external power port. The little LED is clear and looks like a "grain of wheat" tiny bulb. I will check tonight and post if there is any clear give away that it is an LED. If yours is a filament bulb, you can't just replace it with an LED. At the least it will need a seris resistor. Too bad the FR200 doesn't come with a diagram. Terry |

There's some sort of regulator circuitry, as I measured 2.5 volts across the lamp in mine. Neither battery was at that voltage. Somebody here in the newsgroup posted about replacing the lamp with an LED several months ago. Mark Zenier Washington State resident |

That would total about 2.4V if they are 1.2 each as most are. I don't know the voltage the FR200 operates on. |

o quote from my earlier post:
" "My FR200G has a set of 2/3AA NiMH that are charged by the hand crank. It will also take 3?AA cells. and accept +4.5V into an external power port. " They are wired in seris for 1.2X3=3.6V, or some people spec NiMH at 1.25 so 1.25X3=3.75V. I built an array of PV (solar cells) from dead yard night lights that will easily power the FR200G wiht the cells in moderately bright daylght. It willeven powr my 6V DX398. I placed a coil around the radio with only the LED on and my scope shows a nasty pulsing waveform, so I woud speculate the LED is driven by a PWM. Much more efficent then a droppping resistor.
