Sylstar XS1000
Build with the latest Samsung LM301B LEDs, XS1000 has become the most popular small LED light since it came to the market in March this year. It shines brightly with high luminous efficacy of 161.42 lm/w (PS: Luminous efficacy refers to the number of lumens a bulb/light produces for each watt it consumes). In real testing, the input power of XS1000 has reached up to 121.34W, though it has rated power by 120W. Sylstar XS1000 is sold at $129.99 on Amazon. Considering its 291.29umol/s PPF, it only charges 0.45 dollars for each umol PPF. Meanwhile, it has better heat dissipation with a delicate-designed heat sink.
