Home Improvement → Re: Liquid Cooled LED Bulbs

Yes but then the water cooling doesn't work. The hot part of the bulb is at the top, so the water gets hot near that area, but doesn't cycle with cold water, as the cold water is already at the bottom.
Convection only works if heat is generated at the bottom for it to move up and push down the cooler water.

Anyway, LEDs are still way way way way overpriced. They are only worth it for dimmable purposes or ON/OFF stuff like motion sensors.

20$ LED 12,5W = 60W equivalent
2.50$ CFL 13W = 60W equivalent

Yeah... overpriced LED is overpriced.

According to them, the liquid silicone will circulate by convection in any orientation. I can only take their word for it, since the product has not been on the market long enough to test longevity. I'm tempted to buy one and test it out myself.

$12.97 for a 12.5w 60w equivalent LED bulb here. The part you're discounting is cold use and dimming operations where CFL is sub-par at best. There are valid reason to use a mixture of incandescent, CFL, and LED's in a typical household.

I didnt discount either things.

By ON/OFF stuff means not burning out from constantly turning on/off and that they are full bright for motion sensors.

I just find them overrated for their price and their high risk long amortization time when it comes to 100W equivalent bulbs (for motion sensor lights). They'd have to not break for several years before breaking even, and then several more years to have SAVED you enough money to justify the risk.

I'd use them for dimmable lamps since those are typically 40W equivalent or less, so they cost less. I could leave the lamps on 24/7 for mood lighting without worrying about being wasteful. However, my wife hates their color vs. glowing filament.

Anything else than dimmable lamps or motion sensor can use CFL for the same electricity cost and no investment.
