| Subject: | Re: Swivel Overhead LED cabin lights |
OK I finally found the light that I want to use instead of the vents in the overhead
console. Now here is the question to all electrical engineers.
The LED light comes with an LED driver (transformator) which reduces the 230V (AC)
into 12V DC 350mA.
Now here is my question.
Is it possible to leave the the LED driver out and connect the LED directly to
the battery of course with a fuse in between?
Thanks
Michael

I bought the aveo light and have been impressed with it.

The diameter of the Aveo won't fit in the vent recess of the console so it is not
an option.

It depends.
IF there is a current regulator in the LED assembly, then you could plug
directly into the mail bus (which will on the order of 14 Volts during
normal operation). If they have not installed a regulator then you may burn
out the LED's or shorten their life.
The way to find out is to connect them to a bench / adjustable power supply
and bring up the voltage slowly while watching the brightness of the LED.
If you get to say 8 volts the brightness of the LED reaches a peak and stays
constant for the rest of the voltage change, then yes you have a regulator
and it's working. At that point you should be able to connect directly to
the 12 V bus. If not, then the LED will be brighter and you risk shortening
the life.
if they are not too expensive then just plug it in and go for it.
