Switch Lighting’s New Liquid-Cooled LED A-Lamps?

Now, I know what you’re thinking – well, unless it’s hey, I wonder where I put the remote

Switch Lighting has come out with an absolutely beautiful series of lamps that are being tested right now in “several distinct hospitality properties.”  This thing is absolutely beautiful, as are Switch Lighting’s other LED A-lamp designs, holy crap – it’s got panache, it’s got beautiful design, and this cooling liquid inside the dome with the LEDs.  Oh, just check it out – this particular flavor of Switch lamp is the Switch75 (which is a 75W LED lamp, of course, and you can tell from its blue collar!)

Ok, this thing is pretty beautiful, to be sure!  I love the design; just alone, the design is fairly similar to most of the LED A-lamp replacements out there with regards to form.  Heat sink on the bottom, LED dome and some kind of diffuser or magnifier on top, but this one just looks different.  I love how the heat sink continues up into the LED dome, which is filled with a liquid of some sort – I am guessing a mineral oil or some kind of paraffin oil, possibly?  We’ll find out when Switch makes that public!  Something to note is how the LED structure wraps around and attaches to the heat sink – it’s almost as if they used such little material to get the most efficient heat dissipation possible.  If you work with LEDs, you know that heat that they generate is an enemy of their output and life.

Here’s the Switch60 – you can tell it’s 60W because it’s got a red collar:

That thing is just sexy, there are no if’s, and’s, or but’s about it.  I originally saw this post at a great blog called Jetson Green – and I remembered that, wait a minute, somebody tried this before, I wrote about it!  Now, all things aside, the Switch Lighting lamps and the one I wrote about in 2009 are completely different lamps in every regard.  Check it out – this is the EternaLEDs Hydralux-4 liquid-cooled LED lamp.  It’s only 25W, it’s MUCH different than the Switch lamps, and it’s sitting now in my big box o’ lamps:

It’s just a different lamp, completely – fully glass, the liquid is similar to paraffin oil, and there is no heat sink.  It has a frosted top diffuser either formed or blasted into the envelope of the lamp around the LED element.  The only differences are the liquid and the LED parts, really, but I think it is important to see an early version of the liquid-cooled LED technology.  These lamps are no longer offered at EternaLEDs; I did find an old blog post of theirs though that talks a bit about the old Hydralux-4.  It was also featured in a 2009 issue of Popular Mechanics as one of the Top 12 Must-Have Products.  Crazy, huh?

I for one am pretty excited to see how Switch does liquid-cooled LED lamps.  The nerd in me wants to know info on output and efficacy!  Here’s where I kick and scream and beat my fists until no one gives me the info I need.

That’s Right, I Said Water-Cooled LEDs for the Home

A company called EternaLEDs is selling a product called the HydraLux-4 lamp – it’s an LED source for the home and office, fully dimmable, and equivalent to about 25W (the lamp itself consumes 4W).  The biggest difference?  The HydraLux-4 is water cooled.  That was water cooled, in case the first time I typed it wasn’t clear.

It’s no secret that LEDs generate heat.  Heat shortens their lifespan, leads to crappy lumen depreciation, and generally wears and tears at the components of the source.  EternaLEDs’ HydraLux-4 apparently defeats this problem with the water cooling, and claims a 360° light output, unlike a lot of other LED sources on the market.  The HydraLux-4 comes in “warm white” and “daylight white,” with a two-year warranty and 30-day guarantee.

A bit of info from the EternaLED site, comparing the HyrdaLux-4 to other sources:

  • Saves money. At 8 hours a day, the HydraLux-4 only costs $1.75 per year* to run, saving an average of $157.00 over the lifetime of the bulb in electricity and bulb replacement costs.
  • Long Lasting. The HydraLux-4 is rated at 35,000 hours. At 8 hours usage per day, it will last 12 years.
  • Non-Hazardous. These bulbs contain no mercury, unlike CFLs so they don’t require special disposal or clean up. Likewise, the liquid inside is equivalent in composition to baby oil so it’s completely non-toxic and UL compliant.
  • Fully-dimmable. Many LED and CFL bulbs are not capable of being dimmed. The HydraLux-4 is fully dimmable, allowing consumers to create the ambiance they desire by using existing dimmer switches.
  • Outdoor-approved. Many LED bulbs have their components exposed to open air so are can’t be used outdoors. The HydraLux-4 is one of the few LED bulbs approved for both indoor and outdoor use.
  • Cool to the touch. The HydraLux-4 runs cool, cutting down on cooling costs as well as being safe in household applications.
  • Eternaleds plans to announce 8W, 12W and 16W versions of the HydraLux by the end of 2009.
  • The Eternaleds HydraLux-4 comes in two colors, Warm White and Daylight White, and can be ordered directly from Eternaleds.com at a list price of $34.99. Every purchase comes with a two-year warranty and 30-day money-back guarantee.

The HyrdaLux-4 is available on the EternaLEDs website for $34.99.  They’re also saying 2-3 weeks for shipping due to popularity.  It’s a relatively hefty pricetag, but for 35,000 hours it’s not a bad deal.
