2 ChilLED V4 Logic Pucks. Tested pucks in series and individually. Samsung LM301B leds light up dimly. 660nm deep reds don't light up at all. Thermal interface material included. If you're knowledgeable in LEDs or in their repair, this is a chance to get a pair of grow lights for very cheap.

Version 4 boards have improved colored diodes (660nm deep reds for the Red Boost Puck and 460nm blues for the Blue Boost Puck) while keeping the same tailored blend of 3000-5000 Kelvin white diodes in a select mix of CRI

While the Blue Boost Puck excels during veg and the Red Boost Puck shines during flowering, growers can confidently deploy both versions for a FULL CYCLE from seed to harvest

Mix both versions and add Enhancement Pucks to optimize all stages of growth

Designed to fit perfectly on our 140mm pin heatsink without thermal interface material (TIM). If preferred the Logic Puck Thermal Pad can be used for a nominal performance gain
