Dual Spectrum Bulbs

Dual spectrum bulbs have been enhanced to produce the perfect balance of blue and red light to benefit your plants at both vegetative and flowering stages.

Spectral output changes in a HPS lamp as it ages therefore we recommend changing your lamp every 9-12 months for optimum growth conditions.

We stock a selection of 400 watt and 600 watt dual spectrum bulbs including Osram and Lumii.
