Optic LED Slim 650S Dimmable LED Grow Light 650w VS LUXX Lighting 645w LED Pro

 If you’re an aspiring grower or just want to optimize your lighting, check out our guide on the top best LED grow lights. We cover the best lights for your plants for their vegetative and flowering periods.

What are the Benefits of Full-Spectrum LED Grow Lights?

Full-spectrum LED grow lights offer a bounty of benefits for beginner and professional cultivators.

Below, we’ll briefly take a look at each advantage of using a full-spectrum light.

Full-Spectrum LED Grow Lights Grow Big Buds
Indoor plants demand light within the 400–700nm range — and full-spectrum LED grow lights are more than willing to oblige.

Aside from ample light within the usable (PAR) range, most modern full-spectrum LED systems provide small levels of IR and UV light, which further promotes heavy trichome, terpene, and bud production.

Full-Spectrum LED Grow Lights Reduce Electricity Bills
Full-spectrum LED grow lights are incredibly energy efficient because they offer:

Energy-saving diodes
Minimal wattage
High-performing drivers
Heat-reducing technology
Furthermore, full-spectrum LED systems create a domino effect of energy savings by reducing the demand of your HVAC system. Ultimately, full-spectrum LED grow lights are the perfect option to increase bud production while reducing electricity bills.

Full-Spectrum LED Grow Lights are Versatile
Unlike traditional LEDs or HID systems, full-spectrum LED grow lights are perfect for all stages of plants’ growth.

From seedling to harvest, full-spectrum LEDs provide the perfect wavelength of light during the growth cycle. In other words, you can kiss all those expensive HPS and MH bulbs goodbye once you convert to a full-spectrum LED system.

Optic LED Slim 650S Dimmable LED Grow Light 650w

Features:

The Optic LED grow light gives you more flexibility than the usual LED grow lights. Featuring individual dimmers that control different LED colors, the Slim650S gives you full command over how bright each color can get. Switch from vegetating to blooming with a twist of a knob. You won’t need to adjust the height of the Slim650S when shifting phases, thanks to the independent dimmers. The independent dimmers of the Slim650S also let you change the way your plants grow. Turn up the dimmers to increase the potency and quality of your plants. The Slim650S doesn’t scrimp on components, as it uses 3,098 LEDs from Samsung and a Meanwell Driver. It can also work with the Optic LED Master Controller for a more centralized system.

LUXX Lighting 645w LED Pro

Features:

The LUXX LED grow light was developed by evaluating SMD (Surface Mount Device) chips and drivers from leading manufacturers for over 3 years in controlled test applications and cultivation facilities. The LUXX 645 LED PRO consists of Samsung Horticultural White/Blue and Osram Red. The respective companies are leaders in LED research and development, offering high efficiency, reliability and diode performance. The LUXX 645 LED PRO features a 120-degree lens angle, a 6-bar design, and a total of 2,226 diodes. The LUXX 645 LED PRO features manual and automatic power regulation. Flexibility to dim the unit to 40% of total power to reduce photon intensity without compromising spectral quality.

Factors to consider before buying a grow light

How much does a grow light cost?
The first thing to consider before buying a grow light is how much money you want to spend. With more states coming online with adult-use legalization, homegrowing is becoming more popular and growing technology is getting better and more efficient all the time.

You can find lights for under $100, but they may be low quality and not produce the right spectrum of light, and you can also easily spend as much as $2,000 for a large, state-of-the-art LED.

Consider how often you’ll be growing plants and how long it will take to pay off the initial investment — if you grow once a year, it’ll take a lot longer to pay off an expensive light than if you grow multiple harvests a year.

Aside from the price of the actual light, also take into account utilities — all lights will add to your electricity bill every month, but some more than others. High-intensity discharge lights — known as “HIDs” — may be cheaper to buy but can gobble up electricity, whereas LEDs are more efficient and kinder on your electricity bill but usually more expensive to buy.

Another consideration with cost is that some lights run hotter than others — HIDs, for example — so they may require additional fans or an AC unit to cool down a grow space. Extra equipment means more electricity, also driving up your utility bill.

How many grow lights do I need to grow plants?
The typical homegrower will only need one or two lights. Most states limit grow amounts to 6 or 12 plants, and one or two lights should be plenty for that. If you plan on running two separate rooms, one for vegetative plants and one for flowering plants, you’ll need two lights.

How big a light you need will depend on the number of plants you plan on growing, but also on the size of your space. If you’re growing in a closet or a small grow tent, you’ll only be able to fit one small light in there. If you have a wide open basement, you could invest in a bigger light as opposed to two smaller ones.

Power equals poundage, so if you want big yields you’ll need more wattage. Professional LEDs can start at as little as 200 watts, and go up from there. A high-watt light can double the work of several low-watt bulbs.

Conclusion

When it comes to LED Grow lights, I always say you get what you pay for. But if you’re strapped for cash and you only plan to grow one plant, one of these above grow lights is probably your best bet.
