The NXE 400W from GIB Lighting is an incredibly efficient, yet compact and safe ballast, which allows the indoor gardener to care for remarkable gardens. Another practical advantage of this ballast is the choice of four output levels, which on one hand allow for the operation of a powerful 400W lamp, but also allow for dimmed, and therefore energy-saving operation (of HPS lamps only) for less light-hungry phases of the plant?s life.

The popular reflector by Adjust-A-Wings, in efficient titanium white. The reflector, like all Adjust-A-Wings models, is made from light, rust-free aluminium and is coated with a resistant, easy-to-clean polymer sheeting. This sheeting is extremely resistant to heat and distributes the light more evenly than any other Adjust-A-Wing reflector. This reflector reaches slightly lower light reflection values than the Avenger models, for example, but this effect is negligible thanks to the particularly even light distribution.

For more light at a much lower temperature:
Air cooled reflectors from Ventilution can achieve exactly this.
Air cooled reflectors are the solution if HPS or metal halide lighting is to be implemented in a small space. These otherwise magnificent lighting systems have the inconvenient side-effect of strongly heating the surrounding air.
However, this effect can indeed be exploited with the correct implementation to heat the grow room, although the heat generated is usually problematic, especially when multiple lamps are to be operated at the same time.

The 400W Flower Spectre "XtremeOutput" - an efficient model.
The 400W lamp by GIB is particularly popular among beginners and hobby gardeners thanks to its value for money. The phrase "XtremeOutput" refers to the high efficiency value for a 400W lamp. This value indicates how much of the power consumed (W) by a lamp is actually converted into useful light (lm). The GIB Flower Spectre "XtremeOutput" has an astonishing efficiency value of 145lm/W, which is comparable with that of the big name brands.
