It's in full working order/all LEDs functional. This light is VERY bright and promotes vigorous growth in all stages that I've seen. You can look it up on Amazon, (the listing is now for an "updated" version with switches for veg/bloom lighting variations). I would recommend that the switched version is kind of underwhelming, as less LEDs lighting up (in any spectrum) is still less usable lumens/sq.
Otherwise it's the same light as the new ad, as far as internals of the board and diodes. Like all LED sellers and makers, they brag up the wattage quite a bit. All the LED chip and board makers do this and it's a little infuriating, but it's not like King leds are alone here. Photo of LEDs was just to show they work, so that's by no means a measure of the light this thing puts out. I had to mess with contrast and brightness to get the panel to show through the glare.
Here's some details from Amazon about it. 2018 strongest upgrade: brighter more efficient than traditional 3W and 5W LEDs, scientifically engineered to keep the balance of the PAR/Lumen Output and Coverage. Energy saving: just consumes about 380w power, the electricity is 0.38kW·h per hour.
