Sanlight Evo 3-100 – 190W Full Spectrum LED Grow Light for 100x100cm Tents

The Sanlight Evo 3-100 is the ultimate 190W LED grow light designed specifically to maximize yields in 100x100 cm grow tents while drastically reducing electricity costs. This high-efficiency system delivers a perfectly balanced light spectrum that penetrates deep into the canopy, ensuring rock-hard buds and resin production that traditional HPS lamps simply cannot match.

Why growing with old lights is stealing your time and money

Dealing with high temperatures, constantly adjusting ventilation to avoid burning your plants, and watching your electricity bill skyrocket is the reality for many growers using obsolete lighting. The hassle of changing bulbs every few crops and the stress of managing heat pockets makes indoor grow maintenance a heavy, time-consuming burden that takes the fun out of the hobby.

If you ignore this, you end up with stressed plants that produce airy, light buds despite all your hard work. You waste hours trying to cool down the tent, risking pests and mold due to temperature fluctuations, and ultimately, you settle for mediocre results that don't justify the time or money invested. It feels like you are working for the equipment, rather than the equipment working for you.

The Sanlight Evo 3-100 solves this instantly by offering a cool, silent, and plug-and-play solution. Its passive cooling technology eliminates noise and heat issues, allowing you to focus on what matters: watching your plants thrive without the constant headache of environmental control.

How the Sanlight Evo 3-100 saves you time and effort

This fixture is engineered to make your life easier from day one. Thanks to its passive cooling system, there are no fans to clean, repair, or listen to. The aluminum heat sink efficiently dissipates heat, meaning you won't have to constantly battle with your extraction system to keep temperatures down. This stability allows you to leave your crop unattended for longer periods with total peace of mind.

Furthermore, the secondary optics are designed to be tiltable and easy to clean. Unlike other lights where dust accumulates and reduces efficiency, the IP65 protection rating means you can simply wipe the modules down without fear of damaging the electronics. The broad, even light distribution also means you don't have to rotate your plants as often, as every corner of your Mammoth Grow tents receives the same high-quality intensity.

Simple steps to use it without wasting a minute

Getting professional results doesn't require a degree in engineering. Here is how to set up your Sanlight Evo 3-100 for immediate success:

1. Unbox and Hang: Use the included hangers to suspend the light in the center of your 100x100 cm tent.
2. Connect: Plug the power cable into the unit and the wall outlet (daisy-chaining is possible if you have multiple units).
3. Adjust Height: For the vegetative stage, keep it about 40-50 cm from the canopy; for flowering, you can lower it to 30 cm.
4. Tilt (Optional): If you are using it alongside other lights, tilt the optics to direct light exactly where your plants need it most.
5. Grow: Turn it on and let the Osram and Seoul WICOP LEDs do the heavy lifting.

Advantages and benefits in your daily routine

• Zero Noise: Because it has no fans, your grow room remains completely silent, improving discretion and comfort.
• Lower Bills: High efficiency (more than 3µmol/J) means you get more light for every watt of electricity you pay for.
• Less Heat Stress: Your plants transpire less and drink water more efficiently, reducing the risk of nutrient burn.
• Longer Lifespan: With over 90,000 hours of operation, you won't have to shop for replacement bulbs for years.
• Waterproof Safety: The IP65 rating protects the unit from high humidity and accidental splashes during watering.
• Maximum Resin: The specific Far Red spectrum boosts trichome production, giving you stickier, more potent flowers.

Tips to integrate it into your habits without friction

To get the most out of this beast without complicating your routine, pair it with a simple digital timer. Since the Sanlight Evo 3-100 runs cool, you can place your driver outside the tent if you want to reduce temperatures even further during summer. This small tweak takes seconds but can drop your tent temperature by a crucial 1-2 degrees.

Also, because the light penetration is so effective, you might find your plants getting hungrier. Keep an eye on your feeding schedule; using premium full spectrum led grow lights like this often accelerates plant metabolism, so having your nutrients ready is key to keeping up with their explosive growth.

Frequently Asked Questions

Does this light come with a dimmer?

The Sanlight Evo 3-100 is "dimmable ready," meaning it is compatible with magnetic or Bluetooth dimmers, but the dimmer itself is usually sold as an optional accessory. This allows you to customize the intensity based on the growth stage.

Is one unit enough for a 1x1 meter tent?

Yes, for a standard home grow, one Evo 3-100 provides excellent coverage for a 100x100 cm area. However, if you want to push the limits of CO2 cultivation and hit maximum grams per watt, some growers use two units in that space for extreme intensity.

How often do I need to maintain it?

Maintenance is virtually zero. Just wipe the protective lenses with a damp cloth once between cycles to remove any dust or residue. That’s it. No bulb changes, no greasing fans.

Personal Experience of Pevgrow’s CEO (Alan)

I've tested dozens of LEDs over the years, but the build quality of the Sanlight Evo series always stands out to me. When I'm busy running Pevgrow and don't have time to constantly check on my personal garden, I need equipment that I can trust 100%. The Evo 3-100 is exactly that—I hang it up, set the timer, and I know that when I open the tent, the plants will be praying to the light, not suffering from heat stress.

What I really appreciate is the tilting optic feature. In a packed 1x1 tent, the plants on the edges often get neglected, but with the Sanlight, I can angle the light slightly to ensure those side branches get just as much energy as the main colas. It’s a small detail that makes a huge difference in the final weight of the harvest without requiring me to rotate pots every day.
