Sodium HPS Lamp 

Sodium HPS offers exceptionally high output. Couple this with raised spectral discharge in the reds and blues (exactly the right spectral energy distribution curves that your plants need to thrive) and a long lamp life, and you have the perfect plant grow light. This lamp also has 32,000 life hours and colour temperature of 2000K.

250w = 33000 lumens

400w - 50000 Lumens 

600w = 90000 lumens

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