Just when we thought we’d about seen it all, including an actively watercooled LED light, along comes Switch Lighting with a unique design for a Liquid LED lamp. The outward-facing LEDs of the Switch Lighting liquid LED are all mounted on metal fingers which are one with the external part of the heatsink. The LEDs and thjeir metal finger stages are submerged in an inert liquid which allows for heat to flow more evenly throughout the globe and the heatsink.
Switch Lighting claims that the new heat management design allows the liquid submerged LEDs to be ran at higher drive currents, producing 1150 lumens with 10 LEDs consuming just 16 watts. The new liquid LED light is designed to replace a standard 75 watt incandescnet light which is why the LEDs face outwards and why the shape of the liquid LED light is globular. Although this particular light isn’t suited to directed lighting like we need in reef tanks, the concept of a passive liquid cooling could be adapted for all kinds of other lights, allowing fewer LEDs to be driven at higher drive currents, and reducing component costs.
