No question about it, VIPARSPECTRA and MAXSISUN are great brands in their own right; but the most popular brand is definitely VIPARSPECTRA. While the company is based in Guangdong, China, it sells its grow lights all over the world and many have high ratings on e-commerce sites. MAXSISUN LED grow lights are also well liked by growers, but they aren’t as popular.

If you’re shopping for the best fullspectrum LED grow light for your grow room and you aren’t sure whether to go with VIPASPECTRA or MAXSISUN, worry not. We’ve handpicked three lights sold by each company that will suit you, whatever your growing needs.

VIPARSPECTRA Reflector-Series 450W VS MAXSISUN MT450 Timer Control 450W

If you don’t have a big budget but want a grow light that will give you bang for the buck, get the MAXSISUN Full Spectrum Grow Light. While both lights can replace a 400-watt HPS/HID light and use high-intensity 5W LEDs, the MAXSISUN light has a lower price for every watt it draws. It also provides a vegetative coverage of 3.5’ x 2.5’ at 22” while the VIPARSPECTRA 450W light provides a vegetative coverage of 2.5 x 2.5′ at 24”.

The two last lights are powerful ones: VIPARSPECTRA’s 900W LEDGrow Light from the Reflector Series and MAXSISUN’s 1440W 12-band Grow Light.
