Unibody Lani LED from Triton Reef

Very interesting, thanks!

 

Simple spectrum to leverage for DIY designs.

 

80 LEDs including 16 UV LEDs with an emission peak of 405nm, and the remaining 64 diodes evenly spread across cool white Cree XTE and blue XPE.

Also interesting they are only driving the leds at 1 watt.

Interesting to note:

 

You're looking at a 16% increase in efficacy running the Cree's at 1W which is a pretty big deal.  With 3, 1W XT-E's you get the same lumenous output as a single XT-E overdriven at say 5W's.  Now technically, the XT-E was designed to run at 1W and 3W's is called overdrive...  So, it really depends on the LED, and couldn't be a blanket statement "running leds at 1W is more efficient", however, the lion's share of LED's designed in the 2012-2013 timeframe were deisgned around 1W having the highest efficacy (which is the efficiency of an LED taking lumens or mW over input wattage, crossing below 470nm blue we use mW versus lumens).

 

However, payback on the initial cost doesn't justify doing this on most diodes when you consider technological advances year over year.  But, it makes sense with the design aspects of this fixture (100% passive cooling, uniform light spread).
