LED Interior Trailer Lights

I thought I'd try and show a comparison of a new LED wedge base plug in bulb to the standard 1.5v wedge base bulbs that the Chalet comes standard with.

Here is the package

This is the "Warm White". It draws 195mA and gives off 98 lumens. 

This picture is the new LED blub in a Chalet XL1910. The picture is color corrected, but otherwise un-edited. It is also intentionally underexposed and shot with manual settings. You can see the light is less warm (yellow) than the standard bulb, even when color corrected, but not too bluish. There is less spill on the ceiling, but good spread and coverage downward
The next picture is the standard bulb, the same exposure as above . More spill on the ceiling and the light is warmer. But the LED gives slightly better downward coverage. My eye tells me the LED is slightly brighter, but my camera seemed to think the standard blub was just slightly brighter. I'd have to say the light output of both lights is very close. 
This is a correctly exposed shot of the LED. You see good coverage and brightness, with a light that is very acceptable in color to me.
Here is the light without the cover






 Overall, I am very pleased. The LED works great. No appreciable heat from the lamp. Plugs right in to the existing socket. I understand the standard blubs draw 1.5A. The LED draws ~200mA - -that's about 13% of the power for the same ampount of light. Multiply the savings by 4 and the LEDs can save a fair amount of juice when on battery.

Of course, the down side is that the LED blubs are $15 each. In theory they should outlast any owner, but I think that remains to be seen. I do plan to replace the other three when I get $45 I don't know what else to do with. Please respond with any question of comments to the Yahoo A frame groups. Thanks for looking!

  1. Great study. I have been looking at LED's and wondering what model to get since they have many different configurations.

  3. Did you actually measure the current draw of the incandecent and the LEDs?

    No. I simply used the figures on the web site and the 1.5v draw for the normal bulb I found cited several times on the Yahoo A frame groups.

    So...all this could be dead wrong. But, it seems to fit what I have read in other posts and sources.
