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.

Trim & slimming
Size: 16 Short, Color: Deepest Dark
I was so pleased to receive these today. Their title says it all. So well made: the fabric is soft yet the weave is tight, the leg is just the right width at the bottom; and it's comfortably stretchy at the waist and leg. Deepest Dark seems like a true jeans color, blue yet somewhat navy. It's not bright so doesn't call attention to itself. Almost forgot -- the front pockets are just deep enough for a phone.

Slimming Look, Not Too Much Stretch
Size: 8, Color: Blue Format
Some stretch but not too much! I really like these. They hug and pull me in well. I’m slim through the hips with a bit of belly. I’m 5’5” 147.8 and these did not give me a muffin top even though I have a flabby belly. The color is exactly as described. They did not shrink after washing and the quality is what I expect as they are Lee jeans. They are very durable.

Button sucks!
Size: 14, Color: Deepest Dark
These are cute jeans and are great quality, especially for the price. I would've kept them, but had to return them because THE BUTTON IS AWFUL. It is SO hard to get through the hole. It's rounded on the edge so there's nothing to grab onto so it actually hurt my fingers to try to close them. I think the lack of stretch in the top was 25% the culprit, too. They were 100% my size and fit perfectly, so it's not a sizing issue. If I could make a recommendation to Lee it would be to rethink that horrible design and use just the regular button that all jeans come with.

Thighs waaay to big, otherwise literally perfect.
Size: 18, Color: Blue Format
One issue- the thighs were huge. Otherwise these jeans are perfect. They fit great everywhere else, quality material and good thickness. Waist is very comfortable. I wanted so badly to keep these but I knew I'd never wear them. I tried to get past the thigh issue, but they just looked silly.
