dimmable wet cell LED light fixture
Verfasst: 23.01.2019 19:49
I just finished up the conversion of the wet cell CF light fixture into lower power LED. I wanted to maintain similar color spectrum but prefer slightly less pink. While carrying out the conversion, I realize I can modify the fixture to have a high and low selection with minimal and reversible modification.

I set out to intended to install three strips of this LED tape light side by side
the modification is very trivail
I soon realized three strips may generate too much heat for the plastic housing to dissipate and too much power consumption so I decided to use only one strip
there is adequate light with one strip and the power consumption is good compared to about 12W consumption of the original CF fixture
about 360 mA at 13.5V
I did a good amount of bench test to ensure the fixture does not get too hot. Soon I would realize that I can add a High/Low selection with minimal effort. Low is with one strip, and high is with two strips. The High setting is for used when in occasions that I need more light, like cleaning the wet cell.
two strips of LED tape light
here is the secret behind the high/low setting (dimmable)
double the light, double the power consumption and heat
here is the color rendering - which I like for not being as pinkish as the original CF and is not green as a lot of warm white LEDs
for reference here is the color rendering with reference to the galley lights which are very ideal that is warm white on the cooler side
All the details of the conversion are here in my blog:
