Mine is still in its box as i`ve been told they are shite! I am going to hang it next to one of my plants from the side then compare it to another plant on the other side of the tent.
Yeah I have a penetrator 345w running as a test and I am more than impressed. Should be returning me 12-15 oz. Getting harvested in next couple of days.
Have run a 126 penetrator since last xmas with mixed results , would wait another year till suppliers have improved in design and build quality.
Mono directional light sounds great , however the units will only illuminate directly beneath and with a small footprint the cost per square foot is very high.
With 60 deg leds the closest you can get and have blended light is ten inches , 120 would be better for veg i feel.
With six cheap PC fans it was quite loud when new , two died this year and the rest are noisier and will probably fail within six months.
Poor quality soldering required redoing from new , several dry joints and a real danger , failed PAT test even after fixing this , might as well have built it from scratch myself.
According to a callibrated Licor it has lost 12% of its PAR output between feb and oct running mostly 18 hour cycles , more than expected , will be able to borrow the meter again next month and see if its still dropping as fast , manufacturers claims seem over optimistic.
Exactly the same unit from the same factory is sold under different names and in various outer cases , same leds and same dry joints but half the price off fleabay , seriously reccomend removeing the case and checking basic wireing if from china for safety.
Others have had good results and assembly errors may have biased my opinion , but dont think they are the best option for many people in their current form and not yet cost effective , this one is comparable to a 150 CFL but less flexible in its use for me.
i have found them great for the watts they use, especially for micro-grows. you need some kind of intensive method for cramming the buds into the canopy - so they suit my style just fine. no breakdown issues with the three different ones ive used.
