Calendar Event: LED Light dimmers Posted: 22 Dec 2015 at 3:08pm |
I know the ones in my flashlights don't put out the same lumens until the batteries die; they get dimmer as the batteries get older. I'd be happy to swap out my LED's for that kind if I knew where to install the master potentiometer.

Sounds like no extra circuitry in your flashlight, but that makes sense since the voltage will remain in a defined range. Charge cycles on a lead-acid battery can send voltages over 15 volts so it makes sense to limit that, or the voltage can go down to 11 volts so it makes sense to boost that to maintain the light output.
Each light has its own switch so each one would need a pot in the correct ohm range.

We have had our 179 a little over a year now. I have had both cataracts fixed and really notice bright lites. But after using our camper this past summer, I don't notice that they are too bright any more. I must have acclimated. Maybe it is because every time one changes a burned out bulb around the house, the new one is an LED.

I noticed the same thing with some of the LED street lights they've been installing in my area. At first some of them were blinding, but now they don't seem to be as bad.
I just did some poking around on the net, and it appears some LEDs do have a "burn in period". During that time one of their parameters (Vf, forward voltage) changes slightly, meaning less light with the same voltage and current inputs. Maybe someone with experience designing LED circuits can confirm. |

I, for one, really like the Pod lights. I really like how bright they are. The problem with them is their placement, not their brightness. They would be better if some of them provided indirect lighting. On the 179, one or two lights under the cabinet in the slide out would be great. They would light the area over the settee without lighting the whole pod. I am considering a mod to do just that. You might consider using battery powered puck lights in various places for indirect lighting

^^^Interesting you mention lighting under the cabinet. Our 179 came with a light in the spot you mentioned. Sure is nice not lighting up the whole POD. I guess They read someone's suggestion.

If one were to put a light under the slide out cabinet, where would one wire it in?

We just bought a 2016 178 and it has a light in the slide out under the cabinet. The lights are a little bright so the one under the cabinet works great.

I haven't investigated, but since there is 120 AC wired there, I assume that one could find a route through which to feed 12v wires as well. Obviously you'd have to leave plenty of slack for flexing and some kind of protection against possible chafing. |

My wife painted the interior of the light lenses with Rust-Oleum Specialty Frosted Glass paint. She used about 4 or 5 light coats to get the level of opacity she wanted. It provides a nice diffuse light. Unfortunately we did this at the end of the season so we haven't had much real time experience with this change.
