Happy Hydro - that light features 1w diodes which will not give you the best pennetration. Also it advertises 4100 lumens. That's weak sauce. My "180W" (actually draws 130w input) produces 8500 lumens. Something has to be off with their math or specs on that light. Some things to consider when buying LED grow lights. For about 400 USD that is hyper expensive.
1.) total input and output wattage.
2. ) most diodes, even when advertized as 2,3,5w aren't actually driven to the full capacity as this would fry out the diode way too quickly. Ask for a spec sheet.
3.) Warranty - anything less than two years should make you sketch out. Remember these lights are supposed to last 50,000 hours.
4.) Type of diodes used - look for CREE, Epistar, Bridgelux and do a bit of research to see if the company actually uses them or just decided to claim they use them.
5.) Bands - a good one should have at least 4 if not upwards of 7.
6.) Be wary of exaggerated claims. In my experience it will take, at a minimum a LED light running 3w chipsets (driven 1/2 to capacity), with a wattage of at least 180w to adaquetly replace a 400w HID unit.
These 6 tips are based purely on the hours of worktime I spent pissing off researching LED grow lights. There is far too much bs to wade through out there. Hope I've helped.
I'm not here to advocate one company over another but after doing exhaustive research bought several from Hydroponics Hut and am happy with my purchase.
