This is a typical chinese light. However i personally haven't found too many grows using it or the brand ( which is important ). To me looking at grows that are actually USING the panels that you may be interested in can show how well they grow.
Purchasing a panel should give you an idea what it can or cant do.
There are panels that WILL GROW but will not be as productive as say HID or even a COB system. It also depends on your budget. You can get some good results with MARS HYDRO - VIPAR SPECTRA , Black Dog , Area 51 or similar. There are tons of grows using these. You can even look into T-5 Floros which grow well too.
I am moving to COBS but have grown and still grow with LED.
I am using 2 Mars Hydro 600 series II with 2 G8 Deep Red boosters.
Also using a Vipar Spectra 600.
I get great bud for what it is and expect even better with COB. But they will grow well.
Just my 2¢
