Actual power draw and HPS replacing capability

415W is the average actual power draw that Viparspectra Reflector Series 900W LED grow light review sucks from the wall. We count that as a power saver grow light, but we have to accept the fact that the actual power draw of this model is a bit more than many other 900W models.

There is confusion regarding the HPS replacing capability, as the company Viparspectra doesn’t provide with the true number. Similarly like other models, they have provided with a boosted up number. They claim that the 900W model is capable of replacing a 1000W HPS/HID/HP light system, but the results have been different when we tested it in our lab. We found that the right number is 850W.

The coverage area

The coverage area increases or decreases as per the height of placement. We generally count the max coverage area, which is calculated by placing the grow light at the height, that is suitable for the veg area. So, at the veg height, which is 32 inches with this grow light, you get a growing area of 4′ x 4′. When you bring it down to 24 inches for the bloom stage, the coverage area is 3′ x 3′.

16 Square feet is a pleasing grow area with that much price. So, that is on the positive side. In that much growing area, you can easily grow 13-14 cannabis plants.

The warranty

You are getting a 3 years warranty with Viparspectra Reflector Series 900W LED grow light. The customer service is brilliant, so you can fully utilize the warrant for free replacements and repairs whenever needed. The warranty works as per the date mentioned in your purchasing receipt, so keep it safe, as you will have to present it when you need to use the warranty terms. Did receipt lose somewhere? Trouble!

Viparspectra Reflector Series 900W LED grow light review : A quick FAQ round

Many drawbacks are going to be raveled in this portion of the review. So, we recommend you to carefully read, as the info is very valuable, which we have gathered from many sources. Here we go!

Can i expect veg and bloom switches in this grow light?

Definitely, you can! This model comes with Veg and Bloom switches, for both the stages. You just need to turn on whichever you want, and the whole grow light will transform itself according to the need of plant in that particular phase of growth.

Avoid turning On both the switches together during the veg stage, as the intensity of light will increase quite much, and your baby plant will be terrified!

How good is this grow light for a 5′ x 5′ grow tent?

We already mentioned the growing area. This light is not enough for your 5′ x 5′ grow tent, as it will not be able to provide adequate light all-over, which might lead to poor yield. We recommend you to go with the 1200W model of this company to cover your tent fully.

Can I hook this grow light up to my 200W-220W outlet?

Yes, you can. This grow light is capable of working at top power of 265W. By the way, this light comes with US Power Cord (US regular 110V grounded 3 prong plug) if you buy it from the US site Amazon store. If living abroad somewhere, then buy it from the Amazon store of that country, you will get the power cord accordingly.

How are V900 and R900 models different?

V900 is more sq, and R900 is rectangular. The sq is newer, a bit more expensive and is loaded with veg/bloom switches.

What is the darker side of this grow light?

First of all, the company provides with a wrong number of HPS replacement. That brings confusion to buyers and users. Besides that, the company doesn’t provide with the perfect info about the average power draw for each switch as both switches together. As a result, the electricity bill comes higher than the normal, which gives the user a chance to complain.

Besides that, a few users complained that the light is not that good for the flowering stage, in comparison to the veg stage. Not waterproof, so you are supposed to use indoors only. Decent for cannabis, marijuana, and weed, but not that strong to provide you with your desired yield of underground plants.

Just a few inconveniences are there. A few are not happy with the delivery, a few were complaining that their lights went dead before time, and a few complain didn’t actually made any valid point.
