Product Overview

PhotonTube™ is a new LED tube product line that has its light output tuned to the spectral and intensity needs of growing plants. The T8 PhotonTube™ offers 33 umols/sec of photon output, with spectral coverage across the PAR spectrum from 420 nm to 800 nm.

Because this is a full-spectrum product, the resulting light output is a soft white color that simulates natural daylight, rather than the harsh pink/magenta light color typically seen in grow lights. This makes it easier and more comfortable for you, the grower, to see and observe your plants, and spot any diseases or infestations before it's too late.

Our PhotonTube™ LED grow lights are available in 4000K and 6500K, with 95 CRI and R9 > 80 - this indicates a color spectrum that comes very close to natural sunlight.

These T8 LED tubes are UL Type A and Type B compatible, meaning they can be used with or without a fluorescent ballast. Plug it in directly to your existing T8 fixture, or a new fixture with the ballast removed - whatever is easier!

4000K provides an excellent spectral output for strong growth and flowering. In addition to strong output in the blue 450 nm region, RedBoost red phosphor technology ensures sufficient coverage in the deep red portion of the spectrum past 700 nm, targeting chlorophyll A absorption in particular.

The spectral ratio simulates late-season light, stimulating plant processes that encourage flowering and fruit growth.

The 6500K spectrum comes very close to natural daylight, truly simulating what plants have adapted to over many generations. It is especially well suited for seedling growth, and helps to prevent them from becoming "leggy" as the spectral dosage perfectly matches that of natural daylight.

Plants in the seedling stage require significant amounts of blue light to encourage vegetative growth, as it is similar to a high sun-angle spectral composition that is typically observed in early-season grow periods.

Seedling and vegetative growth are absolutely critical components of healthy plants. Without a healthy foundation, plants can suffer from stunted growth and limited yield.

Amazing Sunscreen! Large Bottle and Pump is Great!
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50, Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
I’ve been buying this Banana Boat sunscreen with SPF50 for a while and I wish I found it years ago because it makes putting on sunscreen so easy. Been buying it for family members as well! The pump is amazing—I keep one in my bathroom and one in my bedroom so I never forget. It’s a really big bottle so it lasts a long time, and it spreads super easily with no white cast at all, even on my face. The scent is really light and neutral too, which I love. It just melts into your skin, doesn’t feel sticky, and works for everything—face, hands, arms, legs. It’s one of those products you actually end up using every day because it’s so easy and convenient. I keep repurchasing it for a reason! Highly recommend!

My AmazonFinds/ SPF 50 Sunscreen
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50, Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
I’ve been using this Banana Boat Sport SPF 50 sunscreen and I really like it. It goes on smoothly and absorbs quickly without feeling too greasy or heavy on the skin. I also like that it’s water and sweat resistant, which makes it perfect for outdoor activities or beach days. It provides strong sun protection and I feel confident using it when I’m out in the sun for long periods. The scent is light and not overpowering. Overall, it’s a reliable sunscreen that I would definitely buy again.

Very good sunscreen, advice from a pale-skinned person
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
I'm Scottish by descent, and so is my skin. This stuff works well, is pleasant, not greasy and seems to hang on despite kiteboarding, surfing, cycling, whatever. Pleasant smell, good dispenser.

Good product, the pump bottle could be better
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50, Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This is a usual product for me, I like and trust it. It has little smell, spreads on easily and can be washed off without too much trouble. The pump is nice while it works but I take away one star because it leaves about 20% of the product in the bottom of the bottle when the "cone of depression" gets lower than the bottom of the tube that brings the product up. After the pump can no longer effectively pump the product up, I cut the top of the bottle off and dip the rest out with my fingers. I'm not sure what they can do to make it work better but it's inconvenient as it is.

Excellent protection for workouts and hot days! ☀️🏃‍♂️
Size: 8 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This sunscreen is fantastic for daily use and outdoor activities. The SPF 50 protection is highly effective; I’ve used it under intense sunlight and haven't gotten burned at all. What I love the most is that it actually resists sweat and doesn't run into your eyes when you are working out. It doesn't leave an overly greasy feel, and the 8oz size lasts a long time. It is a reliable product that is always in my bag. 100% recommended purchase!
