Active Grow 22W T8 HO 4FT Horticultural Lamp

Overview 

The Active Grow 22W T8 High-Output Horticultural Lamp is an LED tube that replaces 32W/40W T8/T12 fluorescent lamps and features 30% higher PPF output, lower power consumption and 100% more effective spectrums for plant growth. The T8 LED Horticultural Lamp has a 190° beam angle for wide light distribution and runs cool, so it can be placed closer to plants and save space. Each lamp is protected by ClearSync film technology that improves water-resistance and prevents glass shattering without sacrificing photon output. All Active Grow T8 LED tubes work with existing T8 or T12 fluorescent light fixtures by bypassing the ballast and wiring to single-ended power on universal 120-277 voltage. Without the need for a ballast these lamps do not flicker, buzz or experience longevity issues. T8 fixtures require non-shunted lamp holders (tombstones) and are non-dimmable.

T8/T12 LED GROW LIGHT BALLAST BYPASS INSTRUCTIONS

Fluorescent Fixture Retrofit Instructions

Watch the video to learn the steps it takes to bypass a standard T8/T12 fixture’s ballast by wiring directly to single-ended 120-277 volt circuits. Bypassing the ballast helps not only lower wattage, amperage and heat output but avoids flickering, buzzing, longevity issues and other problems associated with ballasts.

Very cool and comfortable pillows. Great value.
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
These pillows are everything described on the site. They do retain shape and don’t flatten out after sleeping all night. They are nice and clean looking and comfortable. The fit on my king size bed is perfect cause I prefer the size to king size. Haven’t had to wash them yet but I have had other pillows with the same material inside and the wash ability is great.

Great pillow
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
The pillows feel great. Being able to remove portions of the interior allowed me and my wife to have a perfect fit. They do stay cool which seems to have helped with my restlessness.

Better then the fake down style pillows
These shredded memory foam pillows are really comfortable. They’re soft but still supportive, and I like that you can adjust the fill to get the firmness just right. They don’t go flat easily and hold their shape well through the night. Definitely a nice upgrade if you want something more customizable than a regular pillow.

Best pillow!

They work!! My husband and I get really hot and it has kept us cool and I have been sleeping all night since I bought them. Will definitely be buying again! The size is accurate and perfect. It gives me great support for my neck. I don’t wake up with my neck hurting and no headaches.
