Collection: LED grow light – An efficient and energy-efficient solution for growing plants | Cropper

Growing plants indoors requires more than just brightness from your light. The spectrum, intensity, and efficiency of the light directly affect how well your plants develop. That’s why an LED grow light is the modern indoor grower’s best friend – and that’s why Cropper focuses exclusively on providing quality LED grow lights for home and professional growers.

Whether you're a beginner, a home gardener or a seasoned professional, the right lighting is one of the most important factors in successful growing. With Cropper LED grow lights, you can get more out of every growing session - with less electricity consumption and better control.

Why choose an LED plant light instead of a traditional one?

LED grow lights offer numerous advantages over older lighting technologies such as HPS (High Pressure Sodium) or MH (Metal Halide) lamps. Here are the main reasons why you should choose them:

✔ Energy-saving: LED lighting uses up to 50-70% less electricity than HPS lighting.

✔ Cooler operating temperature: Less heat generation means less cooling required and more stable humidity.

✔ Long lifespan: A high-quality LED plant light lasts up to 50,000 hours – significantly more than traditional alternatives.

✔ Full spectrum at your fingertips: LED technology allows precise spectrum adjustment for different growth phases (vegetative growth and flowering).

✔ Safe and compact: No ignition risk, no heavy power supplies – just pure light with optimal power.

LED plant light supports growth at every stage

The biggest advantage of LED grow lights is their ability to provide just the right amount of light for different growth stages. During the vegetative stage, more blue light (450–495 nm) is needed to promote dense and vigorous growth. During flowering, red light (620–730 nm) activates flowering and fruit development.

Cropper LED grow lights contain a full spectrum that mimics natural light and gives plants the signal to grow healthy and efficiently from start to finish. This means bigger yields, better quality and faster growth.

Cropper's selection includes Lumii , Grow the Jungle , Vanguard Hydroponics Cosmos and other popular LED grow lights that offer excellent performance for both hobbyists and professionals. Each light has a clear coverage area, light output (µmol/s) and spectrum diagram so you can make an informed purchase decision, not guesswork.

LED grow light features to look out for

When choosing an LED grow light , pay attention to the following technical features:

• Light output (µmol/s or µmol/m²/s): Describes how much usable light is produced for plants. The higher the better.

• Spectrum: Broad spectrum supports the entire growth cycle – white, blue and red light.

• Lifespan (h): Good LED lights last over 50,000 hours.

• Coverage area (cm): How large an area the light effectively covers.

• Dimmability: Some models allow you to adjust the light intensity for different growth stages.

• Passive cooling: No fan in the design = quiet operation.

LED grow light and grow tent – ​​the perfect combination

The LED grow light works great in combination with a grow tent . The tent effectively reflects light back to the plants, maintains a consistent temperature, and allows you to direct the light exactly where it is needed. Cropper offers ready-made LED grow light + tent packages that make it easy to get started.

The grow tent combined with efficient LED lighting minimizes energy waste and maximizes the development potential of plants.

Development of LED technology – why is now a good time to switch to LED?

LED grow light technology has advanced dramatically over the past five years. Previously, LED lights suffered from low light output and a narrow spectrum – but not anymore. The latest models utilize top-of-the-line diodes, such as Samsung's LM301B or Osram's red diodes , which provide efficient light without compromise.

Cropper's LED grow lights are equipped with these modern components. The end result? Plants that grow faster, healthier and without overheating.

Savings and harvest – in the long run, LED is superior

Although a high-quality LED grow light may cost a little more at the time of purchase, it will pay for itself in saved electricity, reduced cooling needs, and above all, higher yields.

Think of LED grow lights as a long-term investment: they last through multiple growing cycles, require little maintenance, and perform consistently year after year.

Choosing an LED grow light for different growing stages

When choosing an LED grow light, it is worth considering what stage of growth you are in. Different stages of plant development require slightly different lighting conditions. That is why many of the lamps in Cropper's range contain full-spectrum LEDs , which produce the right wavelength for the plant's needs throughout its entire life cycle - from germination to flowering.

🌱 During the seedling stage, blue light is emphasized, which promotes root development and grows dense leaves.

🌿 During the growth phase (vegetative phase), the blue light spectrum is still needed, but also white and a little red light so that the plant can grow strongly and healthily.

🌸 During the flowering phase , red and far red light support flower formation and fruit ripening.

Cropper LED grow lights are designed to serve this entire spectrum. They even allow you to adjust the light spectrum or power according to the growth phase, either with separate switches or dimmers – so you can optimize the light at just the right time.

How many watts do I need in an LED light?

We often get asked how many watts an LED grow light needs for a given area. Here's a rule of thumb:

• 60x60 cm space: 100–150 W LED plant light

• 80x80 cm space: 200–300 W LED

• 100x100 cm space: 300–400 W LED

• 120x120 cm space: 400–600 W LED or several smaller lamps

In Cropper product descriptions, we always state the recommended coverage area and lamp power, so you can immediately get an idea of ​​which lamp is right for your space. We don't offer oversized solutions – just efficient, real-working lights for your growing needs.

When should you replace your LED grow light?

Although LED lights have a long lifespan, their light output can decrease after years of use. If you notice that your plants aren't growing as well as they used to or that they're not flowering as abundantly, it may be time to upgrade your light.

Symptoms that the LED grow light has worn out:

• Plant growth slows or appears stretched

• Flowering is incomplete

• The light tone changes or the brightness decreases

• The lamp gets hotter than before

However, Cropper's high-quality LED lights will last for many years of active use. They are built to last – not just to produce momentary power.

LED plant light is also an ecological choice

LED lighting is not only efficient – ​​it is also more ecological. Lower energy consumption, long lifespan and low heat generation make LED lights more environmentally friendly than older lighting technologies.

Less heat generation means you don't need as much cooling equipment, which reduces the load on the electrical grid. In addition, the long lifespan of LED lighting reduces electrical and electronic waste.

So if you want to grow your plants responsibly and with an eye to the future, an LED grow light is the only right choice.

Where should you place an LED light?

Placing the light correctly is at least as important as choosing the light itself. Here are a few tips for placement:

• Keep the LED light 30–100 cm away from the plants (depending on the power). Always refer to the manufacturer's instructions for the product you purchase.

• Ensure even light distribution throughout the growing area

• Adjust the height according to the growth of the plants – too close the light can burn, too far away the plants will stretch

Cropper's customer service is happy to help if you are unsure about the appropriate height or need advice on placing the light in your growing area.
