not sure 100% because I am not the manufacturer I would call lighthouse on it but on there website it says this
Lighthouse Hydro pioneered the Led grow light industry with the introduction of 3w chips in 2008. You will rarely if ever see a Blackstar in a head to head competition because they were just more powerful than the competition. If you do, it was usually with a light 2X to 3X the price. Keeping that tradition alive we are proud to introduce the first light on the planet using 6w and 10w chips. Our genuine American made Cree 10w chips are not just advertised as 10w but actually pull 10w of real power and deliver a better lumen/watt output than ANY LED in existence. Our new lights offer a concentration of LED so unparalleled, that even straight lumen output (not adjusted for PAR) is greater than HPS and MH bulbs available.
That's for the ion 8 it has 4 white spectrum LEDs that are 10w cree LEDs I am unsure of the panels they may be cree or bridgelux I would contact the manufacturer or a retailer I just use the light.
