When you’re looking for grow lights, a 600w grow light can bring your growing game to the next level. Look for a full spectrum grow light that will cater towards every stage of growth for your plants.

Whether you’re growing a hobbyist, or for your professional needs, a 600-watt light is the great in-between size. Many people start off with a 300-watt light which is great for a single plant, but if you’re looking to grow 3 to 5 plants, you’ll need something a little bigger.

Although the reflector series has many renditions, the 600w is probably the best of the bunch. The Viparspectra 600w Reflector Series has all the great features of its larger counterparts but is more cost efficient, like the Viparspectra 300w.

The Viparspectra 600w Reflector Series can easily replace a 600w HID system, but it only uses about 296-watts of power consumption. This light covers about 3-square feet which is great for 3 or 4 plants. But, when it comes down to plants standing at the full height, your coverage area shrinks to about 2.5 square feet. The center of the PAR map shows a 530 intensity when the lights are suspended at 24-inches above the top of the canopy.

With this light, you can easily program your lighting preferences and times remotely. The remote control that comes with the Viparspectra 600w Reflector Series allows you to ensure full coverage and proper light and dark time rotations.

The t-shape helps ensure a more even coverage. Standard square models have problems with light disbursement. This is not the case with the Viparspectra 600w Reflector Series.

Recordcent is a budget-friendly brand that offers great options for new hobbyists. When you’re looking at the Recordcent LED 600w to grow light,you can see that the unit uses 39 pieces of red light, 11 pieces of blue light, 4 pieces of green/yellow light and 1 each of ultraviolet and infrared.

The spectrum provided here is a mostly full spectrum, and the red light helps your plants grow and can increase potency. The red lights work to provide the essential nutrients throughout the flowering stage.

Aside from the spectrum, the Recordcent LED 600w grow light offers a lot of efficiencies as well. Usually, with more cost-effective lights, you lose out on a lot of efficiencies. However, there’s not a lot of power draw for this 600w light.

The Recordcent LED 600w grow light, however, falters when it comes to area coverage. During the vegetative cycle, there’s only a coverage area of about 2.2 feet by 2.7 feet. Then that reduces further during the bloom stage. There’s also not enough “white” light mix, or the yellow/green light to pierce through the canopy effectively.

Things to consider to Buy 600W Led Light

Great value for grow lights is a combination PAR, intensity, and lifespan. If you have outstanding lights with a full-spectrum, you’ll be sorely disappointed if they only last for a year or so.

When you’re ready to make your final decision, you should rely on your budget and immediate needs for the best light. It’s easy to get caught up in extra features such as dimming, and timers but these aren’t necessary for hobbyists. Now, if you’re a professional looking for a new light, you should be willing to invest in the tools you need for a high-yield and quality potency.

PAR and More

PAR is one of those terms that growers like to throw around, but it’s not all that easy to explain. Let’s start with light wavelengths. It’s important to consider that your plants need a wide variety of light spectrums, mostly those which stimulate growth or photosynthesis, and those that help them gather and retain nutrients.

You want a grow light that will produce only the light spectrums that your plants need. Typically plants don’t need 550NM or 750NM.

A full spectrum light will provide the bands of color within the PAR spectrum. The PAR spectrum refers to the wavelengths between 390nm and 700nm. These light wavelengths and their quality vary between manufacturers.

When you consider how your PAR can affect your end product you should focus on finding a grow light with an adjustable spectrum. An adjustable spectrum gives you more control over the PAR and gradually take your plants from one stage to the next. Usually, the gradual adjustment helps plants continue thriving rather than the shock of flipping on a veg or bloom light.

Greenlight is another light spectrum to consider, which is often forgotten. Usually, plants reflect green light (it’s why the plants are green), but it’s useful. Greenlight helps the areas of your plant that growers typically forget about, the leaves! Happy plants are happy all around, not just producing optimal yields.


Some people look for a grow light with a ton of white LEDs believing that it will pierce through the canopy, and help out their plants. But, although a ton of white LEDs looks intense, it’s the wrong kind of intensity.

Because there are no true white LEDs, there’s no advantage to the brilliance you see coming off of some lights. It’s true that typically the brighter a light shine, the more intense it is, but that’s not the deciding factor.

Stay away from anything that claims to have a lot of white light because typically they drag on energy efficiency and are detracting quality light from your plants.


Cannabis cycles through 3 primary growth stages. The first is seeding which comes very naturally and requires very little interference from you. Instead of focusing on the light during the seeding phase you need to ensure that their roots are taking hold and getting all the nutrients needed.

The vegetative state, however, is when you should start worrying about lights. Many grow lights have a vegetative light switch that directs power to the lights that will help encourage photosynthesis and nutrient absorption. When you’re considering aspects such as nutrient absorption you should focus on having a full light spectrum, including green light.

The final cycle, the one most growers, are concerned about is the bloom or flowering stage. This phase of the cycle directly affects the potency. Many growers are finding that you can increase your yield by focusing on red and infrared light. However, growers report that an increase in blue light during this phase leads to a more potent product.

Choosing the best grow light for your plants requires outstanding performance throughout their entire lifecycle. Although very serious, and heavily medicated, growers can afford to purchase various lights to use at different phases of growth, you should look for one that will do the job well.


Our top pick is the Viparspectra Reflector Series 600w, with its unique reflector technology. When you compare the Viparspectra 600w Reflector Series to any other 600-watt light series, it’s clear that this light is the best value.

You get a full 12-band spectrum, with ultraviolet and infrared LEDs in a unit that has high-speed cooling fans. This system is known to work for years, and it has decent area coverage. This light is great for all stages of your plant’s growth cycle.

If you’re looking for something to care for some plants with, the Viparspectra 600w Reflector Series is a great choice.
