So a new day, a new LED fixture build. As some of you might remember, a couple of months ago I did a a full spectrum LED cannon build consisting of 9 LEDs but I was never happy with the way it looked and wanted something cleaner.
This time around I am setting up my CADlights low-iron rimless tank which has the same dimensions as the ADA 90-P. For this tank I wanted to stay with LEDs but wanted something very simple. 6 months ago this would not have been possible but with the arrival of the Bridgelux Vero series things are a lot different.
The Bridgelux Vero series is a new multichip array which is more efficient than the BXRA ES series and offers way more power with increased CRI. CRI is important because it's the reason we go multi-colored LEDs in the first place. Most common stuff today (Rebel ES, Cree XP-G, XT-E, XM-L etc.), all suffer from low CRI (70's) in the cool white range (5500-6500K CCT). This means that all these white LED's suffer from a lack of red and green in their spectra which is why we augment with colored LEDs. The new Vero series is able to put out a rated minimum of 90 CRI in a cool white (5600K CCT) LED with the Vero 18 and 28. This means that we can get a lot closer to a full spectrum LED with a single chip.
This is the data sheet for the Vero 18 I will be using BXRC-56G4000-F-04.
As you can see this particular LED can take up to 2A and deliver a whopping 6000 lumens for a very low price of $15 from digikey. I know some people prefer a bluer light on their tanks so if that's the case this is not the LED for you. Also Bridgelux rates the CRI on their chips as minimum and are known to measure higher in real world use. Also you know these emitters are built to last when Bridgelux warranties all Vero series for 10 years.
Another awesome thing about these chips is that they are solderless ready and just require a Molex Pico-EZMate connector which can be purchased here:
