By sunlike full spectrum, we mean that the light is capable of distributing all the wavelengths that are usually found in sunlight. For this feature, the LED grow light can help the plants to get all the essential rays including red, blue, white, purple, orange, UV, IR, etc. These waves of multiple lengths are very helpful for the rapid growth of the plants.

Plants require different bands of lights at different growth stages. TSW 2000W can satisfy this requirement by making most kinds of rays available, thanks to the full spectrum feature. The light emits visible waves such as red rays at 620 ~ 750 nm, blue rays at 450 ~ 495 nm, white lights of 5000k, and warm white lights of 3000k.

The variant wavelengths help the plants to survive and grow at any stage of their life cycle. With the dimmer knob, you control the wavelengths and light intensity to match the plants’ lighting requirements. You can also make the environment suitable for different growth stages like seedling, veg, flowering, and fruiting.

The manufacturer’s reference indicates that the light intensity should be limited up to 25% at the seedling stage, up to 50% at the veg stage, and hover between 75% – 100% during flowering and fruiting stages. So, you should realize your plants’ requirements and control the intensity accordingly.

The latest LED technology of this light is highly efficient in producing better-quality light at a minimal cost. The manufacturer uses Epistar’s SMDs in the bulbs. These upgraded diodes ensure higher PAR emission at even dispersion around each of the corners of the grow tents.

At the normal state, TSW 2000W can provide PAR at 1122 µmol/m2/s from an optimal height of 18″. This high rate of PAR generation stimulates plant growth and provides a better yield. Reportedly, this light can contribute to a higher yield up to 2.5g/w on an average. This is a better result than any of the other old fashioned grow lights.

This LED grow light is almost square in shape that can cover a wide area with even dispersion of light and PAR. The core coverage capacity of this grow light is 3’x3’during the flowering stage of plants’ life. However, the ideal coverage is 4’x4′ at the veg stage of the plants’ growth cycle.

This 4×4 LED grow light consists of 684 pieces of diodes with 2000 watts integrated capacity.  However, the light can save energy with higher efficiency. It draws only around 300 watts from the power output. This way, it can save big bucks on your electricity bills. This high-efficient grow light can produce light at 2.35 µmol/j on an average.

Though a bit heavy, the design of this model is very sleek and attractive. It has a power switch for controlling the light function easily. It works noise-free since there are no cooling fans installed. So, you may feel a bit hot under it. But the aluminum body can absorb some of the temperatures.

But it can provide coverage up to 5’x5′ indoor grow space quite well for the plants during their veg time.

This light features intense scalable lighting to fit different growth stages of plants. You can control the brightness of light with a knob set on the frame. During the seedling or veg stages, the plants usually require light at low intensity. And during the blooming time, the same plants will require more intense light.

The manufacturer suggests that this light should be placed above 30 to 36 inches above the plants’ height during the seedling stage, 26 to 30 inches above during the growth stage, and 22 to 26 inches above during the blooming time. Maintaining the correct height will bring you the perfect plant growth and sustainability.

This light contains natural full spectrum wavelengths. It can provide different mixtures of white, red, and blue lights for helping plants grow and produce heavily. The deep red light of 660 nm wavelength is beneficial for the plants at their growth stage. However, in this light, you will find a lower number of red light-emitting diodes. So, this light may work less effectively on the plants at their veg stage.

But, by combining with the warm white lights of 3500k and cool white light of 6500k, even the deep red light may benefit the plants at their veg stage. On top of that, the wavelengths work strongly on the plants undergoing their blooming stages.

The invisible IR rays help the plants during their flowering stage, while the UV rays work during this stage, but only for the last couple of weeks. The right lengths of light ensure the appropriate plant development which is the biggest plus of this LED grow light.

PB4000 is capable of producing great PAR around the grow space. On average, it can emit 2.70 µmol/j PPF which indicates an impressive performance for such a grow light. This higher PAR amount is necessary for the plants to execute the photosynthesis process to produce a high volume of carbs.

  • Yield: 2.5 grams per watt (on an average)

Bloom Plus’s new creation is BP3000 LED grow light. It has included some latest technologies in the main panel and the driver. The Samsung 2835 diodes are the latest of their kind and much more efficient than the previous versions. These diodes make the light an efficient one to provide bright light which is a prerequisite for productive plants.

With the efficient diodes, the PAR distribution of these lights turns to be on the higher side. The average PAR distribution of this light is 2.7 µmol/j which can turn your efforts into great yield. The efficiency of these lights can be put into numbers. You can get 2.5 grams of yield on an average when the light burns for a watt-hour which seems a great performance.

The grow light has been designed very attractively with a thin light panel with 11784 pieces of powerful diodes on it. Many of you may get impressed by its design only, even if we put aside the high performance. Moreover, you don’t have to think of risking the bulbs fusing or getting the main panel wet as the light panel is totally water-resistant.

It depends on the aluminum-made heat sink for dissipation of the temperature generated due to producing bright light. It has no cooling fan installed to deal with the heat. As such, you may sometimes feel that there is some extraordinary heat inside your grow tent which can also hinder the usual growth of the plants.

The positive thing you can make out of this is that the light works without making any noise the whole lifetime. Firstly, there are no fans to produce any humming sound. Then again, though the driver is not a branded one, it produces no buzzes either. So, you can work peacefully under this grow light.

The full spectrum feature has reached another level with a stronger red color with all other necessary colors for plants’ survival and growth. The versatile spectrum lights work on the plants’ development and result in a great harvest for the indoor gardener. When you get an optimal spectrum of lights, your large yield will come not just at a lower energy cost but also within a minimum time.

For your information, different plants require a different level of light intensity at different stages of their life cycle. So, you must know the lighting requirement of each category detailing their growth cycle needs. For your convenience to manage this dynamic requirement, the light driver comes with a dimming feature. With the dimmer plot, you can tune in the strength level. However, you’ll have to use a small lever (a screwdriver will do) to utilize this feature.
