LightWave T5 LightWave T5 lighting has proved to be a revelation for plant production and for aquariums. Light for living things T5s used in propagation will produce even growth and bushiness with short internodes and thick stems. However, unlike other fluorescent lights they can be used throughout the growth cycle to produce mature plants of great quality. The LightWave Advantage The perfect colour temperature for plants, aquaria and reptiles just watch the response. Reduced heat output allows closer positioning to plants, fish or animals. Ideal for use in enclosed spaces less heat build-up. T5 fluorescent tubes maintain lumen output longer and generally cost less than HID lamps. LightWave T5 fixtures take up minimal space and can hang vertically or horizontally. LightWave T5 will support both vegetative growth AND fruiting and flowering.
