Cosmos 45W LED Grow Light – Full Spectrum & Passive Cooling

The Cosmos 45W LED Grow Light is the definitive compact lighting system designed to provide your plants with the exact spectrum they need for vigorous vegetative development and explosive flowering, all while keeping temperature and energy consumption under strict control. It is a high-efficiency technological piece that replaces bulky, hot, and outdated equipment, offering you a professional solution in a minimal size.

Is your grow tent a chaotic oven of cables and heat?

Problem: We've all been there: trying to fit a hot HPS or a bulky CFL into a small space. The result is usually a disaster. You have ballasts taking up space, cables tangling everywhere, and worst of all, an uncontrollable temperature that forces you to install noisy extractors. Your plants suffer from heat stress, and you suffer every time the electricity bill arrives.

Agitation: This disorder not only looks bad, but it also ruins your results. Heat burns the terpenes, stress stops growth, and the lack of space makes working with your plants a nightmare. Instead of enjoying your hobby, you spend your time fighting against the environment, moving lights up and down so as not to burn the tips, and complicating your life with equipment that is too powerful for your square meter.

Solution: The Cosmos 45W LED puts an end to that chaos. Its ultra-thin, lightweight, and silent design allows you to organize your space efficiently. By emitting hardly any heat and having the driver integrated, you eliminate external ballasts and complex ducting. It is the order and simplicity you need to focus on what matters: growing huge, resinous buds.

How your grow space changes once you add it

Imagine opening your tent and seeing a clean, clear, and silent environment. By installing this LED board, the visual noise of thick tubes and heavy reflectors disappears. The light is distributed evenly, reaching every corner without creating "hot spots" that damage the leaves. Your setup looks professional, tidy, and optimized.

Furthermore, the workflow improves drastically. Since it doesn't emit the brutal heat of sodium, you can get the light closer to the canopy without fear, maximizing photon absorption. You gain vertical space for your plants to stretch, and the environment remains stable, allowing you to control humidity and temperature with much less effort. It's the difference between fighting your grow and flowing with it.

What you can manage with this product

This equipment is not just a light; it is a versatile tool that allows you to organize different types of crops and stages in small areas or Grow tents 60x60. Here is what you can handle with the Cosmos 45W:

• Germination and Seedlings: Perfect intensity to start without stressing the little ones.
• Mother Plants: Keeps your moms healthy and branching without triggering flowering.
• Rooting Clones: Gentle and effective light for high success rates in cuttings.
• Micro-Growing: Complete cycle (Veg + Bloom) in spaces up to 60x60 cm.
• Supplemental Lighting: Ideal for illuminating those dark corners in larger grow rooms.
• Auto-flowering strains: Continuous light spectrum for fast cycles.

Steps to build your organised set-up

Getting your indoor garden running smoothly is easier than ever. Follow these steps to integrate your Cosmos 45W:

1. Check your space: Clear the area and make sure you have a sturdy bar to hang the light.
2. Hang the system: Use Lighting Accessories like pulleys to suspend the LED board. Its light weight (0.67 kg) makes this super easy.
3. Connect control: Plug the LED into an Indoor light timer to automate the photoperiod (18/6 for growth or 12/12 for bloom).
4. Select the mode: Use the built-in switch to choose the spectrum: "Vegetative" for growth or "Bloom" for fattening buds.
5. Adjust distance: Start at about 30-40 cm from the tips and lower it as the plants acclimatize.
6. Quick check: Verify once a week that the height is correct as your plants grow.

Advantages and benefits of having everything in its place

Switching to the Cosmos 45W LED technology brings order to your cultivation and benefits to your pocket:

• Full Spectrum Control: Includes 395nm (UV), 3000K, 5000K, 660nm (Red) and 730nm (Far Red) chips. You cover all needs with a single device.
• Passive Dissipation: The aluminum body dissipates heat naturally. Zero noise, zero fans breaking down.
• Energy Efficiency: With 2.5 µmol/J, you get more light for every watt consumed compared to old technologies.
• Durability: With a lifespan of 50,000 hours, you forget about changing bulbs every few months.
• Dual Switch: Change the spectrum with a button, without changing the lamp or moving equipment.
• Water Resistance: IP54 protection to withstand the humidity of the indoor environment.

Frequently Asked Questions

What area does the Cosmos 45W cover?

It is designed to optimally cover an area of 60x60 cm during the vegetative phase and about 40x40 cm or 50x50 cm for intense flowering.

How much heat does it emit?

Very little. Thanks to its LED technology and aluminum heat sink, the temperature is minimal compared to HPS or CFL, allowing you to better manage the climate in small tents.

Do I need an external ballast?

No, the Cosmos 45W is Plug & Play. The driver is integrated, so you just have to plug it into the current (or your timer) and that's it.

Can I use it for the whole cycle?

Absolutely. It is a Full spectrum led grow lights system. You just have to play with the height and the switch to adapt it to growth or flowering.

Personal Experience of Pevgrow’s CEO (Alan)

I have tested the Cosmos 45W in a support closet where I keep a couple of mother plants, and the change in organization was immediate. Before, I had a CFL that took up half the space and was fragile; now, with this thin board, I have gained a lot of vertical height and the plants look much more robust thanks to the full spectrum.

A trick that worked for me: during the first weeks of flowering, I keep the switch on "Veg" combined with "Bloom" if possible (or just ensure the height is lower) to encourage stretching, and then I focus purely on the red spectrums. The resin production I've seen with such a small device is ridiculous. It's the best investment to keep a small crop tidy and productive.
