The Mars Hydro SP150 is a full spectrum LED with Infrared (IR) to achieve maximum photosynthesis. Manufactured using the newest SMD LED chip technology, the SP150 can achieve an average yield of 1.8g/w (power draw) or 2.75μmol/J. A max. yield of 2.5g/w is achievable with the right conditions. Compares to traditional 250w HPS/MH using 322 LED's while consuming only 135 watts! 

Perfect for a 60 x 60cm area or tent. 75 x 75cm vegetative coverage at 60cm (24") and 60x 60cm flowering coverage at 45cm(18"). The SP150 is a fanless design using the whole casing as a heat sink. This makes your growing life easy and quiet with NO noise at all.
