HB-660 LED Grow Light Product Description:

Be confident that you will increase your yields and crop quality with this super bright LED grow light, HB-660! HB-660 is a full spectrum LED grow light meant to provide enough uniform light for a 4’ x 4’ grow space. It features quality components and has some features that make it stand out in the market.

The HB-660 draws true 660 watts from the plug. It is supposed to have an equivalent light output of a 1000-watt HID bulb. The PPF is rated at 1716 μmol/s with almost every photon absorbed by the plant and efficacy at 2.7 umol/J.

HB-700 uses the quality white diodes designed by Cultiuana which cover a wide spectrum of PAR and produce more intense light with fewer watts. It also incorporates the most efficient Osram 660nm diodes that create an ideal spectrum for vegetative and flowering stages.

However, strong and efficient light isn't the only thing Cultiuana is going for. We know uniform coverage is what every grower cares about most when shopping for an LED grow light. To achieve this, our engineers used 8 bars with a foldable design to spread the light evenly over your canopy, including the lowest parts, and algorithmically placed diodes to create a great uniformity of coverage. So with a single light, it's easy to cover all angles of your grow area evenly.

When you check the PPFD chart, you'll see that in a 4×4 growing surface area, the average PPFD reading is 1138 μmol/m2 from a height of 12 inches. It stays consistent in literally every part of the surface area, even when hanging at a low height, it ensures the contribution to the edges and corners.

The onboard dimming knob is accurate in the PAR ranges. It has preset options for 40%, 60%, 80%, 100%, and external control. So by dimming up or down the light, you can fully control the efficiency at any given time.

Have a larger growth? No problem, as 50 lights can be connected through the daisy chain ports and controlled by a single dimmer or controller.

The HB-660 truly doesn't get hotter than the stated maximum operating temperature of 113°F/45°C. The passive cooling mechanism is designed very effectively with heatsinks, so you probably won't need any active fan to cool down the light.

We offer a 7/24 online service, a 5-year limited warranty, which is about the industry average, and a free return for an exchange/replacement.

Good Shelves
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 3, Size: 22.5inches
These shelves are really nice quality and look as advertised. The hardware included was great quality, metal drywall anchors and good screws. They were easy to install, and make even/level with each other. My only gripe is the price, but I'm very satisfied with the product overall.

Attractive, easy to install, nicely equipped hardware package.
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 2, Size: 22.5inches
These are pretty doggone nice shelves and I appreciate the fact that they are not made of solid particle board. Yes they are made of an engineered product, but they are lightweight and strong…and look better than particle board products and more costly than their actual price. Easy installation system with the bracket…not fussy like some are. An especially thoughtful touch is the variety of hardware that is included. Also a tiny level for use when installing them. What? …So they can be installed correctly? I was pleasantly surprised by this inclusion.

If the set screws were white the shelves would be perfect.
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 15.7inches
I'd give 4 1/2 if there was one. The shelves thwmself are nice I just don't like the visible little black set screws. The shelves themself look great and are not wobbly at all if you install correctly. I purposely installed the bracket upside down because of the little black setting screws; I didnt want them showing because the shelves are above eye level and the screws are black and I didn't want them showing. But that made the shelf lean amd wobbly so I turned them back over the way they are supposed to be and that made them level and sturdy. I guess I'll paint the little screws.
