What customers say about "Key Specs"
VIPARSPECTRA Reflector V300 Grow Light Full Spectrum for Indoor Plants
  • First off I will say this LED is the best on the market for many reasons. I own a 300W KIND LED and used in comparison..
  • 5Watt diodes ( need I say more ? ) competitors still using outdated 3Watt diodes..
  • This was my first LED purchased for an indoor grow. Heard good and bad about it but overall seemed better than most on price range.
  • Good luck on your LED purchases and if you are considering an affordable good quality light, viparspectra is solid!
  • These lights are made with Gallium Aluminum Arcenide as part of the manufacturing process of LED's. It is a very toxic compound .
MarsHydro Pro II CREE 600W LED Grow Lights Full Spectrum
  • I have used LED lights for 10 years and tried Six different brands. I do my own Par readings and can say the advertised readings are true.
  • I switched to LED from CFL lighting and am very pleased with the results.It does what it's said to do. I did a lot of research before deciding on this light, and it lives up to the hype.
  • The LED light was nowhere near as "bright" visibly but human eyes are not an indicator of light strength for proper photosynthesis.
  • It has been a really solid product and seems well made. I don't have other led lights to compare the growing quality to.
  • I've had the light for 19 months, and 4 blue LEDs have now burnt out. I do have two of these lights and the second one is still working properly.

What customers say about "Lighting"
VIPARSPECTRA Reflector V300 Grow Light Full Spectrum for Indoor Plants
  • Easy to set up, got two for a 4'x4'x8' - just ordered one more for complete coverage.
  • HOWEVER, they recently changed the model so the lighting is slightly a different color but the coverage area is a lot better.
  • Great coverage, lightweight, full spectrum lighting, easy setup, great for small indoor gardens.
  • I grow three big plants in a 4x4 tent using two 600's and one 300, and the coverage is perfect.
  • The light is a nice even mix of RED / BLUE lights and covers the full spectrum... I heard of complaint about too much blue / white light..

  • Light coverage is good. I find the foot print to be a little closer to my plants to reach lower branches.
  • I'm thinking of purchasing an additional light for more coverage, but this one alone works great.
  • The light had good coverage of a 3x2 area of lettuce, at about 24 inches height. They were left on for 20 hours a day. As of now I'm impressed at the value, and hope it lasts for years.
  • Light is bright, good size coverage being it's kinda smaller than I thought.
  • Works great no heat keep house or room at a good temp, will,get another one if you can afford to get a bigger one instead of these two small ones, little coverage.

What customers say about "Features"
VIPARSPECTRA Reflector V300 Grow Light Full Spectrum for Indoor Plants
  • Have three of these and they are working great. Love the daisy chain feature for the power.
  • The daisy chain feature is also extremely convenient, that being the main reason I plan on getting 2 more.
  • The daisy chain feature on this product is also amazing, allowing you to connect multiple devices together. The blue/purple color that this thing emits also adds a nice aesthetic touch to whatever room you are in.
  • he chaining feature is a big bonus for cord management. I bought 2 and they worked so well I bought the 600w and it's amazing.
  • It is thick, solid and well built. I made the mistake of looking directly at it when I turned it on the first time and I saw spots for the next hour.

  • The built in fan is nice, especially if your plants like a little air circulation. It doesn't put out too much heat overall, which is a real perk when growing highland plants.
  • Operation of the light is flawless, the fans are pretty quiet compared to the in-line fan needed to cool a 600 HPS.
  • It is a bit loud with its fan but not too bad. It has been a really solid product and seems well made.
  • Fan is loud. It's a 120mm fan. The last model had 3 fans and 100 leds, now it has one fan and 60 leds -- less materials means less price for us.
  • The only drawback I would mention is that the fan can be a little louder than some people may be looking for, although its nothing crazy.
