Regular LED Lights Vs. LED Grow Lights: What Is The Differences?

by | Oct 4, 2023

When growing your plants indoors, it’s essential to understand the kind of light your plants need. That’s why we’re comparing two light types: grow lights vs. regular lights. Between these two lights, which should you use for your plants? We’re going into detail about the difference between grow light and regular light, giving you a good option for indoor plants.

As an indoor gardening fanatic and LED light manufacturer, we always try new tricks to help your plants thrive. For some time now, we’ve played around with different kinds of lights, from regular bulbs to fancy LED systems. Lately, we’ve been wondering—what’s the difference between regular LED lights and specialized grow lights? Are those spendy grow lights worth it for hobby gardeners like yourselves? Let’s look under the hood and review the difference between grow lights and regular lights.

Why Light Matters to Plants

First, a quick plant biology lesson. Light is food for plants—it’s how they make their energy to grow via photosynthesis. During photosynthesis, plants soak up light mainly in the blue and red wavelength ranges. Blue boosts leafy growth, while red drives flowering and fruiting. Plants will also use other colors, such as orange, green, and purple, for growth and development. But blue and red pack the biggest punch for healthy plants and excellent yields. Plants get spindly and sad without enough blue and red lights, producing wimpy flowers or fruits.

The Basics of Grow Light vs. Regular Light

Let’s start with the basics, shall we? A regular LED light is your everyday household light, illuminating your space and keeping the darkness at bay. On the other hand, a grow light is like a superhero version of light, specially designed to fuel the growth of our leafy pals. The main difference? A grow light is tailored to provide the specific light spectrum that plants crave for optimal growth.

The Science Behind the Difference: Grow Lights vs Regular Lights

Grow lights and regular lights might seem like close cousins, but they are distinct in their structure, design, and intended function. Let’s dive into the fascinating world of how these luminous marvels are crafted.

Regular Lights

Regular lights- the kind you use at home, the office, or the streets—primarily focus on human lighting needs. Their goal is to light up our spaces nicely and bright. To do this, they’re built with a few essential parts:

  • Light source– Regular lights typically use old-school incandescent bulbs, fluorescent tubes, or modern LED bulbs to make light. Incandescents create light with a hot filament, and fluorescents glow with gas and a coating. On the other hand, LED bulbs use fancy semiconductor diodes to emit light.
  • Reflector – Regular lights often have a reflector to spread light around evenly. It bounces the light outward so the whole room gets illuminated.
  • Housing and fixture – This is the body of the light, holding the light and reflector in place securely.

Regular lights are designed to give off a broad rainbow of visible wavelengths we can see. The light usually mimics natural daylight, making it perfect for lighting our human spaces and activities.

Grow Lights

Grow lights, on the other hand, are made specially for our leafy green friends. They’re crafted to meet the unique needs of plants, helping them grow, make food, and stay healthy. Making grow lights involves truly understanding how light affects plants. Here’s what makes them tick:

  • LED tech – Grow lights use cutting-edge LEDs as the light source. These LEDs emit particular wavelengths that perfectly match what chlorophyll in plants absorbs.
  • Spectrum control – Grow lights let you adjust the light recipe, tweaking the intensity and balance of colors. This spectrum control is critical for mimicking the sun and optimizing plant growth.
  • Heat management – High-tech heat dissipation keeps growing lights cool, preventing damage to lights and plants. Proper temperature is critical.
  • Reflectors and lenses – These direct and focus light falls onto plant leaves, maximizing absorption and minimizing waste. It makes sure light reaches where plants need it most.
  • Durable design – Grow lights are built to last in demanding plant environments. High-grade materials withstand years of use.

Grow lights are intricately designed and engineered to provide customized light tuned for nurturing thriving plants indoors. By tailoring the spectrum and light qualities for plants, grow lights create the perfect environment for happy, healthy plants to flourish.

So, why choose to use grow lights over regular lights?

How Regular LEDs Fall Short for Indoor Gardens

Most normal LED bulbs and fixtures are designed for human vision. They produce white light across the color spectrum, with peaks in short blue and long red wavelengths. This works fine for lighting your kitchen but is not ideal for indoor gardening.

Regular LEDs don’t deliver enough oomph in those key red and blue bands plants crave. Instead, they waste energy generating green, yellow, and orange hues that don’t do much for plants. Regular LEDs squander light that your plants can’t fully use.

We saw these limits firsthand when supplementing our indoor veggie garden with regular LED bulbs. The tomatoes and pepper plants were leggy and produced smaller yields than buds under grow lights. The regular LEDs weren’t cutting it for indoor cultivation.

How Grow Lights Are Tuned for Indoor Gardening

LED grow lights are designed specifically to provide optimal light quality and strength for plant growth. While designs vary, full-spectrum LED grow lights have a few traits that set them apart from generic lighting.

Dialed-in Red and Blue Wavelengths

Quality grow lights concentrate output primarily in the blue and red ranges, delivering a higher proportion of usable wavelengths to rev up plant growth. More blue means bushier, compact growth, while extra red drives bigger blooms and yields.

Full-Spectrum Capabilities

The best LED grow lights offer a careful balance of blue and red LEDs supplemented by other color wavelengths like orange, green, UV, and IR. This full-spectrum coverage ensures plants receive light energy optimized for all their growth phases and metabolic needs.

Brilliant Light Intensity

LED grow lights are engineered to produce super high-intensity light, or lux, within those key color bands that drive photosynthesis. This enables them to light even large grow spaces with many plants sufficiently. Intense narrow-band light is far more efficient than filtering unwanted wavelengths like regular light.

Adjustable Light Cycles

Advanced LED grow light systems let you program custom light cycles tailored to your plant’s needs. Mimicking the natural day-night rhythm with precision timers helps plants thrive through each growth stage. You can easily simulate the perfect light schedule for seedlings, veggies, or fruiting plants.

Putting Grow Light vs. Regular Light to the Test

We set up a side-by-side indoor veggie garden experiment to see firsthand the difference between grow lights vs. regular lights. We grew tomatoes, peppers, and lettuce under 600 watts of equivalent regular LED bulbs in basic fixtures. And we grew the same veggies under a 300-watt full-spectrum LED grow light bar designed for plants.

Mid-season, the contrast was unmistakable. The plants under generic LEDs were spindly and needed staking to stay upright. Their leaves were minimal, with new blooms and fruits slowing way down. Under the grow light, the plants were bushy and self-supporting, with abundant foliage and steadily ripening tomatoes and peppers.

At harvest time, the numbers said it all. The veggies grown under regular LEDs yielded less than half of those under the equivalent wattage grow light. For us, this simple test clearly showed that LED grow lights are the way to go for indoor gardening.

Key Differences Between Grow Lights vs. Regular Lights

Based on our hands-on tests and plant light science research, here are the critical differences between standard LED bulbs and full-spectrum grow lights:

  • Spectrum: Grow lights concentrate in plant-friendly blue and red spectra. Regular lights emit a rainbow of visible wavelengths.
  • Light Intensity: Grow lights maximize usable intensity within key color bands. Regular lights have lower, diffused intensity across colors.
  • Efficiency: Grow lights waste less energy on unused wavelengths. Plants can use more of their light.
  • Coverage: Higher intensity grow lights can light larger grow areas versus regular lights.
  • Customization: Grow lights offer adjustable light cycles. Regular lights provide fixed illumination.
  • Plant Growth: Plants show more vigorous growth, higher yields, and better fruiting with grow lights.

Reap the Benefits of Full-Spectrum Grow Lights

Adding specialized LED grow lights instead of regular LED bulbs to our indoor garden is game-changing. The grow lights enabled our garden to thrive year-round while using minimal electricity by providing intense, full-spectrum light tuned to plants’ needs.

If your indoor garden struggles under standard lighting with spindly, low-yielding plants, switching to full-spectrum LED grow lights can help it reach its potential. Give your plants the lighting they need, not just what works for humans. Once you see your plants respond with robust growth and bountiful blooms and fruits, you’ll never go back to regular LEDs.

Research shows that the right light spectrum and strength significantly impact plant growth, yield, and potency. That includes your cannabis, lush tomatoes, and leafy greens. The magic of growing lights helps all kinds of plants. Whether maximizing your tomato size or making your basil extra flavorful, a well-chosen grow light can take your gardening to the next level.

Making the Right Choice Between Grow Lights vs. Regular Lights

Now that we’ve got the lowdown on the differences, which light should you pick? If you’re a serious grower aiming to optimize plant growth and increase yields, the choice is clear: go for a specialized grow light. These plant lamps are purpose-built for the green wonders in your garden and will give you the most value in the long run.
