Sort of makes me wonder what the normal operating temperature of the LED bulb is, and what kinds of temperatures the liquid-cooled one is likely to get to after 4-5 hours of being on.

Also, lifespan, power usage, all the normal stuff. And price, of course!

Here's some info that might help:

Product Description

The Eternaleds HydraLux-4 LED Bulb is the first LED bulb in the world to use liquid-cooling technology to give true 360 degree light like a regular light bulb! It uses 4W to put out as much light as a 25W standard "A-Shape" incandescent bulb while lasting 35x longer. It's a drop-in replacement that can instantly replace any indoor bulb that uses a standard E27 medium base socket.



This LED bulb is great for applications such as: desk lamps, sconces or anywhere you'd use a 25W incandescent bulb. Not to worry, if you drop/break it - the liquid inside is harmless paraffin oil that has been tested and certified safe to UL and ROHS standards.

So would the light output be diminished if it was an upwards-facing bulb? (ie. a standing lamp)

Umm. How does the liquid cool the LED? Wouldn't it just heat up?

Should this be renamed World's first incased-in-liquid-to-slow-rate-of-temperature-increase bulb?

Check the link in my reply>> ^silvercord:

Then consider that the liquid brings the LED's heating capacity to a point of no return where their ability to continue heating the oil is negated by the properties of the oil.
