VIPARSPECTRA 450W LED Grow Light, with Veg and Bloom Switches, Full Spectrum Plant Growing Lights for Indoor Plants Veg and Flower

Well made easy to use

Powerful and option to use in veg only for plant growth or flower setting. It's my first light so I can't compare against others but stuff is definitely growing much better under this.

Arrived quickly, and well packaged, in a plain box.Light works well, but has far too much blue for flowering.I thought growth was ok, but i just replaced with a mh, and growth just exploded.These panels are ok, but will not match hid lighting.To edit, light has been used to supplement hps. Its doing a good job of that. I may buy some more.2nd editBought a second one.I don't use these on there own. They are used to supplement hid lights.On their own, they were good at raising seedlings, and cloning.But for good floweing results, you would need at least 4 of these, for every m2. The use full footprint of the 2 units in the picture, is 1.5ftx1.5ft. You will get better results with hid at the same wattage.I like them for the ability to boost the blues and reds, as needed, with mh and hps.3rd edit....Randomly started to receive interference, down my broadband line, and so did my neighbours. After 2 weeks of tests by BT, they finally found one of these panels giving out rf signals, with a spectrum analyser.

I had other LED before, nothing compares with Viparspectra. It last 2 years on average or even moreVery cost effective

It’s an ok light for veg needed 2 for a 3x3 and worked very well together one isn’t really enough. Will light burn at 12” so reasonable PAR output

It’s cool, it’s quiet, it’s strong enough light if your just wanting it for your own plants. Happy days

Only had it a couple of months now but it appears to be doing what it advertises lol

Good light. Runs nice and cool and have had nice results so far. Im very happy with it.
