Just recently, Mars Hydro has started to use 5W diodes in the Reflector Series. Before that, the lights had 3W diodes. The increase in wattage enables the diodes to emit more light, compared to the past products.

It has been one of the primary reasons why value growers have shifted to these lights for better results. Nowadays, LEDs are better than HIDs in terms of energy efficiency. LEDs are made to last approximately 50,000 hours and remain energy efficient. With 120V, the Reflector 48 can produce 102W with +5% and with 240V it can produce 100.6W with +5%.
