Equivalent to 60w incandescent. Not 60w LEDs.
Its actually baby oil
Basic Math:
1 + 1 = 2
1 * 1 = 1
Water, or baby oil, or whatever the liquid is, will conduct heat better than air. Let's say the LED is 2cm across (huge I know, but makes my math easier). The surface area would be 12.56 square cm. However, in a 10cm sphere the surface area is 314 square cm. The smaller area is too small for the heat to be conducted away via air, but if that heat is first taken away by a liquid to a surface area that's 26x bigger, then we have enough surface area to be cooled by air.
LEDs generate heat! But very few if they have no high package rate. Heat is the death of every semiconductor. So best way to extend lifespan of LEDs is to make good allocation of 20mA LEDs. A standard LED stripe with 60 LEDs on a flexible thin board generates only a handwarm surface. So this will be the best way in future. Not liquid cooled high power leds.

$35 may seem like a lot - but with a mtbf of 35000 hours, assuming it's on 8 hours a day, 7 days a week, that's 11+years - does about $5 a year INCLUDING power cost sound better?
