New LED Replacement for A-Type Lights
See The LED Light in Action
I’ve been watching a new LED bulb called the HydraLux. These LED based bulbs are filled with a clear liquid coolant to help dissipate the heat. Unfortunately the coolant is paraffin oil – highly flammable and I don’t know exactly how the bulbs are rated as non-toxic as paraffin is a petroleum distilate.
Most commercial LED bulbs use large aluminum heat sinks or even fans for to cool them. I think the idea of using a liquid coolant is “brilliant” (excuse the pun) but I’d spend a bit more time in R&D looking into different liquids.
The bulb uses only one 4W Cree LED to produce the equivalent of a 25 Watts from an incandescent bulb. It has a higher color temperature than what we usually see with low wattage bulbs so it will appear slightly blueish. But take the bulb over by your window and it will look perfectly like sunlight.
The HydraLux sells for about $35 (ouch!).
Check out the video for more info.
I still use old cell phone chargers to power 1 – 2 1watt white Cree LEDs for 1 – 2 dollars each. I figure the 12 minutes it takes me to make a task light saves me $33.00 which works out to a pretty good hourly rate. Now, why am I blogging when I can be making more $ with DIY LED lights?

seems like paraffin is generally accepted as non toxic it was used to seal preserves for years and i think it is the basis for the wax they put on most fruits and veggies at the big markets. is it totally harmless? probably not but seems like there are bigger concerns that the toxisity of parrafin. the flamability does seem like a potential issue but if it is sealed from O2 then that is proabaly not a concern either.

Paraffin is relatively non toxic. Emphasis on relatively, It also is like Napalm if it gets on you and ignites.
Just imagine little lights in your house filled with diesel fuel. At a certain temperature the things will explode.

LED can lights and bulbs do require a significant heat sink, but it’s a small trade-off when you think about the amount of energy wasted as heat by incandescent bulbs, i.e. 90%. If an LED bulb is just going into a lamp or other fixture that can take the standard sized bulb, I’m not sure what the advantage of these Hydralux bulbs is (besides a novel design.) Especially if they’re potentially little molotov cocktails!
