The Johnson Grow Lights CX-1L is perfect for vegging in a 2x2 area or flowering in a 1.25x1.25 area. The small fixture measures 7" x 7" and uses a single Top-Bin Citizen CLU048 3000K COB LED. The full spectrum is heavy in red while providing enough blue light for tight internodal spacing and a lot of green light to increase photosynthesis rates in leaves and below the top of the canopy. The unit only draws 60W but will replace a 100W HPS.
The CX-1L is fitted with a large secondary lens which helps to increase intensity and penetration. A single cooling fan helps draw cool air over the heatsink to assist in preserving the longevity and efficiency of the LED.
Growers wanting to install several of these units can daisy chain up to 10 CX-1L's together.
This fixture is perfect for growing up many seedlings, several clones, vegging a couple plants, or flowering a single plant. At £119.55 and a 3-year warranty, you can't go wrong.
The Mars Hydro Reflector series has been a top-seller in the LED grow light market for many years. The fixture provides a great balance between price and intensity. There are 96 5-watt Epistar diodes on the Reflector 96 grow light. The diodes are surrounded by small reflectors to direct the light to your plants. The diodes, with the driver and fans, only draw 205W at the wall while covering about a 2x3 area for veg and a slightly smaller area for flower. The unit is designed to replace a 250W HID grow light.
Growers can switch between grow and bloom mode with a flip of two switches. Veg mode is heavy in the blues, while the flower mode activates the reds, needed for optimal flowering. The Reflector 96 measures 23" x 10".
Like most LED grow lights on the market, this light has a flexible driver and is rated at 85-265V. Furthermore, depending on your country, a North American, European, or Australian power cord/plug is included with the fixture. 2 year warranty.
The Mars Pro II series is Mars Hydros newest series and features the highest quality build and best reflector design.
The Mars Pro II Epistar 80 is ideal for vegging a 30" x 30" area (6.25 sq ft) or flowering an 18" x 18" area (2.25 sq ft). There are 16 modules on the front of the unit. Each module contains 5 different LEDs - typically 3 reds, a blue, and a white (to round out the spectrum and increase intensity and penetration). The reflector cup surrounding the diodes assists in directing the light downward instead of scattering the light to the sides.
As with the Mars Reflector Series, this unit (and series) features grow and bloom switches to help you save energy during veg. The unit only draws 81W with the grow switch on and 170W with both switches activated. The Epistar 80 only measures 11.4" x 11.4" and is ideal for smaller grows and tight spaces.
