I test and evaluate the BUDTECH V8 COB LED grow light. It consumes 386 watts and covers a 4ft x 2ft or 120cm x 60cm space with an average PAR of 909 µmols/ m ²/ sec which is a really high performance level. The system effectiveness is 1.7 µmols/ watt usable PPF per watt which is not as high as most led bar type lights. However it is well constructed and uses high quality elements such as Vero 22 LEDs by Bridgelux and Meanwell motorists so it should last a long time.
