LED grow Light

Online it says this light pulls only 40w so I wouldn't think that they much good they cheap Chinese fakes that don't do the job

Never heard of them but I would assume if it's actually pulling 280 watts from the wall it should be good for a 3x3.

I'm a big fan of LED's and use Sunblasters products, they have a craft cannabis line and regular line for other growing. but there is a lot of shifty marketing out there for LED products. I did find that manufactures webpage, but they have a lot of different models. and no search function. https://www.sinjialight.com/ this was the closest product to 280W light that I came across, 240W https://www.sinjialight.com/240w-quantum-board.html every other thing pointed me towards alibaba... https://www.alibaba.com/product-detail/SINJIA-New-280W-Full-Spectrum-Greenhouse_1700000502139.html I'll base my findings off of the manufactures info. not Alibaba's. It will reflect on the company as a whole. side note, the images used in the alibaba add are for a light that Sinjia does offers, but they say there light pulls 40w not 280w like Alibaba. Product models match ZW0298 as well. https://www.sinjialight.com/led-bar-grow-light.html A few things that stick out as weird to me/red flags to me, 1) It's adapter is 36V at 2.1amps. Volts multiplied by amperage is wattage. 36 X 2.1 = 75.6Watts draw max on the adapter. so why is a single LED quantum board that is said to be pulling 240Watts have an adapter that can only supply 75.6watts?? and why is the item listed at 240w but then in the description it says its 200W?? 2) There is no testing results posted on their lights, PAR or PPFD outputs, spectrum annalist. what kind of LED's are on it?? 3) Most of their products are blupule blue purple LEDS and they are not as good a full spectrum. 4) The majority of sellers for their products are on Chinese wholesaler sites like Alibaba or aliexpress. that's not necessarily a bad thing, but its not a good place to purchase high cost equipment. over all I get the felling they are selling products that are misleading and you will loose out on money invested for a inferior product. If this is not the correct product please point me to the one you are talking about by using weblinks and model numbers.
