You mean the cost of their Cree LED ??http://www.ecosunlite.com/e_productshow/?48-CREE-XPE-LED-48.html
Yeah, they are XPE . A 5 year old chip ,but it means they make their LED Grow light with Cree led chips and top quality one , area 51 with Cree , AdvancedLED with Cree , both are good quality and well-known by growers .
When we know the LED chip they use , such as Cree , Osram which we all know good quality LED chips . If we know their led chips brand and the price is good , then we prefer those Brand LED chip Grow light ,
