Jeff at EternaLEDs sent me one of the HydraLux-4 liquid-cooled LED incandescent replacement lamps a few weeks ago – I took some images of the lamp when I was still in Dallas, and I have to say that I liked it! I requested a high color temperature source – the lamp comes in “Daylight White” and “Warm White.” I was interested in the higher color temperature to see how the source compared to compact fluorescents in our house – in the 25W category, the EternaLED kicked some butt in my opinion. I have the 4W version, but rumor has it that 8, 12, and 16W versions will be out by the end of the year.
I wrote a post about the lamp a few weeks ago, but I was able to get my hands on it and run it through a few paces. It’s dimmable, it’s obviously instant in power-up, and it is cool to the touch when energized. I conducted lux measurements on the HydraLux-4 lamp while it was installed in my bedside light fixture, where it replaced a 25W incandescent. The color temperature of the lamp it replaced was lower, but I prefer the higher color temperature. At a distance of about a foot, the HydraLux-4 had an illuminance of 52 lux (about 5 footcandles), which decayed to about 8 lux (about 0.75 footcandles) at 6 feet – which was approximately the distance from the source to my pillow for reference.
One of the cool things about this lamp is that if you drop it and it shatters into pieces on the kitchen floor (like I almost did while taking a picture), it’s full of a paraffin oil, which is not poisonous. It’s approved for indoor and outdoor use, and is supposed to last 35 times longer than incandescent sources of the same range.
