4 ft. Toggled Focused Spectrum grow T8/T12 horticulture/gro tubes (12-pack) are engineered to provide improved growing performance for green leafy plants using selected LED output wavelengths. Peak wavelengths of 455 and 640nm are optimal for light absorption leading to better plant growth. Ideal for garden, hydroponic, and greenhouse applications.

  • T8/T12 Retrofit LED (Installation kit included)
  • High efficiency grow light technology (Only uses 16 watts)
  • Reduces excess heat in grow operations and water evaporation
  • Triangular tube shape engineered for uniform, wide-beam light distribution and low-heat allowing lamps to be placed much closer to plants
  • PPF 29.84 μMole/sec, PPF Efficacy 1.8 μMole/Watt
  • PBAR 34.12 μMole/sec, PBAR Efficacy 2.1 μMole/sec/Watt

As with all Toggled direct-wire LED products, grow tubes are mercury-free, energy efficient, and designed to work in standard T8 and T12 fluorescent tube fixtures. Following a simple retrofit process to bypass the ballast system, Toggled grow tubes run directly off of building line power eliminating ballast system failures and associated replacement costs.

      Great coffee grinder!
      Color: Silver
      Amazing product. Easy to use and has different grades of grinding. Zero noise compared with an electric grinder and more control of the results (consistent). His size and weight make it portable and easy to carry.

      Quite good as a start grinder
      Color: Silver
      Very good burr grinder with very functional adjustments. Holds the perfect amount in 1 go for my pour over setup. My only critique is that is has 3 unconnected hopper sections that are quite small and hard to hit. I have to be very careful to not spill and one can fill before the other 2 causing some difficulties closing the crank, but it just takes some self adjustments to get around. Overall I'm very pleased with it for the price.

      Great Quality, Great Price.
      Color: Black
      I have used this for a few days now and it works great. It is very well made and has a large range of adjustability. It is quite small and easy to store. Definitely worth the money.

      Nice Grinder at a Great Price
      Color: Black
      I bought this to use primarily as a travel grinder and found that it is great for every day use. It is not meant for large amounts but it is perfect for single, smaller brewing situations. The grind selection worked well and I "dialed" the proper ground size for my single sized pour over coffee maker.

      Ceramic burr destroyed itself
      Color: Silver
      For the first two-plus months it worked fine -- the perfect grind and the perfect amount with a full barrel for my oversized coffee mug. I've been using it once daily, more or less, on a medium grind setting of 25, and this morning the ceramic burr started to eat itself. This is not acceptable. Follow up: Circle Joy contacted me and offered to give a full refund on this purchase, which was gratefully accepted. This is outstanding customer service.
