# How Much Electricity Does A 600w Grow Light Use UK?

To get the total in pounds, divide the number we came up with by 1,000.

So, over the course of 10 weeks, your ‘600w’ light will cost you a total of 84.42 in power.

To determine the precise wattage being used in your grow, use a plug-in watt meter to verify the wattage of each unit in operation, and then add all of those figures to your calculations.

Again, the electricity cost calculator we built simplifies the procedure. You should definitely give it a shot.

## How much does it cost to run a 600 watt grow light?

The cost of running the lights is \$0.2735236 each day, or \$8.20 per month. Using the same technique of computation, I would pay \$30.90 per month for a HID (high intensity discharge) lamp with a 600 watt bulb. Of course, I could grow my own tomatoes and other veggies indoors with a metal halide HID lamp.

## Do grow lights in the UK consume a lot of electricity?

A 600 watt LED grow light’s average daily energy consumption is 0.6 kWh x 16 = 9.6 kWh. This gives us a daily cost of living in the United States of 9.6 x 0.1375 = 1.32 dollars. It’s 9.6 x 0.28 = 2.688 pounds a day for UK people.

### Actual Wattage

This is the real amount of energy consumed by the fixture. When functioning at maximum power, 600 watt LEDs consume roughly 400 watts. The Optic 6 is an exception in that it consumes more energy (but also produces more output).

Some of these lights are programmable and can be adjusted to operate at a lower power level. Plants do not require as much light during the vegetative stage of growth as they do during flowering. When LEDs are not in use, a fixture that allows you to turn them off (or reduce their intensity) saves you money on electricity.

### Spectrum

All four fixtures offer full-spectrum light, with the majority of them additionally including UV-A and IR wavelengths. The distinction is in how white light is used. Two of them employ all white COB LEDs (one also includes colorful diodes), while the rest use diodes of various hues (white, blue, red, IR, UV)

See our post on the best 1000w LED grow lights for an explanation of the difference between all-white light and light made up of many colored diodes.

Two of these lights provide you differing degrees of control over the spectrum’s makeup. The Optic 6 allows you to run only the COBs, 5w LEDs, or both at the same time, and the SolarSystem 550 can be customized using a different controller. The SolarXtreme 500 and the PhytoMax-2 400 have a set spectrum.

### Light Output

The output of 600w LED fixtures is roughly equivalent to 600 watts of HPS light. We granted 5 stars to fixtures with an intensity equal to or slightly higher than that of an equivalent HPS bulb, and 4 stars to fixtures with an intensity lower than that of an HPS lamp in our ratings. In terms of output, the Optic 6 is similar to a 1000w HPS, while the SolarXtreme is equivalent to 800w.

### Canopy Penetration

Almost every manufacturer claims that their LED light penetrates as deeply as HPS light, although this is rarely the case. However, we chose these lights because they match, if not outperform, HPS lighting. We granted 5 stars to lights that genuinely outperformed an HPS bulb, and 4 stars to lights that were close.

### Coverage Area

During blossoming, this is the area in feet that the light will cover. They can cover an extra one to two feet when vegging. During vegging, a light that covers 4 by 4 feet during flowering will cover 5 x 5 to 6 x 6 feet.

## Is it true that grow lights increase your electric bill?

Your electricity bill will rise as a result of installing a light system; the exact amount will depend on the size of the system and the number of hours it is used. However, most grow lights are quite energy efficient, so you get a lot of light (and growing power) for your money!

## What is the maximum number of plants that a 600W LED can support?

You can be confident that when you grow autoflowering seeds indoors, they will receive the ideal atmosphere and will grow as well as they possibly can, depending on how you treat them. When these plants are young, they don’t appreciate a lot of water, and if you over-water them, you’ll end up with dwarfed plants rather than regular ones. It’s entirely up to you how big they grow, so if you’ve never grown autoflowering strains before, plant a few more than usual in case any of them end up dwarfed.

They’re ideal for when you need a speedy harvest because certain strains only take two months to grow from seed to harvest; autoflowering plants also have incredible strength, scent, and effect. There are two types of autos: two-month plants and three-month plants. 2 month plants should yield around 40g each plant, therefore you should be able to fill a square meter with roughly 9 plants and receive up to 400g per 600w light. However, because 3 month autoflowering plants develop significantly larger, you should only plant 4 per 600w light. If all goes according to plan and you don’t over-water them, you should have a fantastic harvest. If you’re thinking about planting autoflowering seeds, take a look at our article on auto strains.

Now that you know how many plants to put in each light, it’s time to put your knowledge into action! Many growers believe that utilizing more plants would result in a higher yield, however using too many plants can completely wreck your grow and leave you with absolutely nothing from what could have been a profitable operation.

## How much does a 60 watt LED light bulb cost to run for 24 hours?

Assume you have a 60-watt incandescent lightbulb and your energy bill is 12 cents per kWh. Leaving the bulb on for the entire day will cost you 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = around 20 cents in a single day.

## How far away from plants should a 600 watt light be?

It’s one of the most common questions we get from growers, and we are asked it on a daily basis, often multiple times!

So, let’s answer the age-old issue, “How close should I put my grow lights to my plants?”

• You use what kind of light (HPS, CFL or LED)
• The wattage (or power) of the light you’re using
• The temperature directly above your plants’ canopy
• What kind of plants are you growing?
• You have a certain amount of vertical space accessible to you.

If you’re unsure, a decent rule of thumb is to stay 1-2 feet away from your plants’ canopy. Some plants behave strangely when the light is dimmed, while others thrive when the light is shone directly on them.

Some growers say they can’t get the light source close enough to the plants when using greater wattage HPS lighting systems. There are numerous options for resolving this:

• A clip-on fan can be pointed at the light to cool it down and drive the hot air away.
• Upgrade your lighting to a cool tube or air cooled system.
• Use an HPS light, CFL light, or LED light with a lower wattage.
• To suck the heated air out, get a higher-powered extractor fan.

Taking all of the above into consideration, the best distance for your HPS system to be between 12 and 18 inches away from your plant is between 12 and 18 inches. You should keep your plants close together in the early stages of their lives to avoid straining, but as they grow larger, you can move the HPS light further away.

Because LED grow lights don’t emit nearly as much heat as HPS systems, they may theoretically be placed much closer to your plants without harming them. LED lights are more penetrating than HPS lights, although the quality, view angles, and coverage regions of different brands of bulbs / kits vary.

In general, you should set your LED grow light 6-12 inches above your canopy, while different manufacturers offer varied recommendations according on how their lights are constructed.

When determining the distance between your LED light and your plants, a good rule of thumb to follow is to get them as close as possible without sacrificing the coverage area and giving enough of room for them to grow into.

CFLs are similar to LEDs, but they don’t have the same penetration as HPS or LED lights. One of the most significant disadvantages of CFL grow lights, and one of the reasons why growers choose to utilize several CFL lights, is that they are inefficient.

Another issue with CFL lights is that if they are placed too close to your plants, they can, will, and do burn them. With this in mind, you’ll want to get your grow light as close to the plants as possible while keeping it far enough away to prevent them from burning.

Depending on the wattage, your CFL: grow light should be 2-5 inches away from your plants.

You can do a lot of damage to your plants if you place your grow light too far away from them. The most serious issue is stretching, which occurs when your plant makes an extra effort to grow taller in order to be closer to the light source.

Because they focus all of their energy on coming closer to the light, they don’t devote as much energy to growing fruit, which can reduce yields by as much as 30%. Let me repeat: you could be getting 30% less fruit simply because your grow light is too far away!

On the other hand, if the grow light is too close to the plants, it can cause difficulties. CFL and HPS lights are the most visible issues, as the heat they release can easily burn the tops of your plants.

When the light source is positioned too close to the plant, many gardeners report odd or stunted development.
