1. Heat Loads

One of the most vital factors when purchasing LED grow lights for indoor plants is their heat output. It is because LED grow lights need to be close to plants for a long time. 

The poor construction of LED grow light could cause overheating, and it tends to burn out faster. You’ll need to replace it sooner, resulting in higher maintenance costs and time. Excessive heat will also damage the plant, such as the burning of plants.

In this case, I’ll suggest you LED grow light as LEDs produce low heat output. It allows protection and proximity to plants, besides a longer lifespan for LED grow lights. You should also choose a light with a proper cooling system like attached heat sinks to eliminate the heat.

2. Productivity 

This is the second important factor in sourcing the best indoor LED grow lights. Look at the Photosynthetically Active Radiation (PAR) Value. It is measured µmol/m2 per second to calculate the number of light that reaches your plant per second. You can use a PAR light meter to determine how many photons are given out by our LED grow light.

It is recommended that you provide your indoor plantation 700-900 µmol per second. You should also allow even light distribution to have proper buds size. The LED grow lights from Darkless LED produce 1730 to about 2,300 µmol per second. It is a relatively high Photosynthetic Photon Flux (PPF) and uniform output.

Remember that you need to switch on the LED grow light for around or over 10 hours per day. That is why you need to keep your total light output within 300W to 1,000W – anything lower or higher will not be efficient. High productivity means good energy proficiency, and it will save more energy as well as your electricity bills.

3. Programmability 

It means the available settings in various variants, like light intensity, spectrum, and color. Why do we need so? Because plants require different types of wavelengths for each growth stage for photosynthesis. For instance, vegetative and flowering growth need red lights, while microgreens need blue lights. Plants will also need adequate ultraviolet and infrared for healthy growth. 

A LED grow light with flexible settings will be a perfect light source for indoor seedlings and houseplants. You’ll be able to grow a vast range of plants as you want, regardless of the season or region you’re in!

You might want to consider schedule settings for your indoor plantation. It allows remote control or pre-set schedules to switch on or off and what lights to produce. Don’t you think it will save you a lot of hassle?

In this case, the LED grow lights by Darkless LED could provide a superior full spectrum for your plants. This high-energy efficiency could help you achieve greater output at harvest. Besides, our controllers are protected against short circuits with double temperature safety features. You can auto-shutdown at its temperature settings.

4. Components and Materials

You should purchase durable LED grow lights made with high industry-standard materials and certified production methods. In this case, LED grow light is a good choice as it can last for around ten years. 

It is vital to check on other additional accessories, like the lights, fans, filters, ducting, and grow tent. With the best components, you’ll have fewer changes needed to prevent extra costs and hassles.

Note to consider the quality of semiconductor chips, as it is the core of LED grow lights. The purpose of these chips is to convert electricity to light and define the required wavelength. Make sure they are at least 3watts to provide adequate illumination.

5. Scalability

LED, HID, and CFL are popular grow lights today. Let’s compare their scalability:

LED grow light is the leading-edge technology that surpasses HID and CFL. You can find many scalability advantages in LED grow lights. You can learn more about How to Choose a LED Grow Light in this article. 

HID grow light is a rather good grow light for most commercial use, yet less advanced than the LED grow lights. 

CFL grow light has the least efficiency in light output and yield among the three options. It best suits small-scale plant growth by hobbyists.

Type of Grow LightsProsCons
LED (Light Emitting Diode)Low heat output- Best in energy efficiency – Long lifespan- Uses standard outlet Higher initial cost
HID (High-Intensity Discharge)Efficient production- Simple installation and operationHigh heat output- Limited lifetime- Need special socket, hood, and ballast
CFL (Compact Fluorescent Lamp)Cost-Efficient- Widely available- Suitable for small scale- A wide variety of color temperaturesLow light output- Less efficient- Must be placed close to plants- Less fit for bigger scale

6. Safety 

You should also evaluate LED grow lights’ safety before purchase. It is crucial to check on the color and intensity of the LED grow lights to be comfortable for your eyes. 

Besides, choose a LED grow light with less fragile materials. In case of collision or knocking down, the LED grow lights will be less likely to break, shatter, or explode. It is due to the smaller-sized diodes and the production way of lights.

Other safety concerns are fire and mercury. Make sure you have a suitable electrical outlet suitable for the long-time operation of LED grow lights. Grow lights except LEDs might contain mercury that is harmful in case of light breakage. 

So, make sure you communicate your concerns with your supplier before purchasing LED grow lights.

7. Applicability

You should choose the appropriate LED grow light according to the plants to be planted. It is because some grow lights are specially used to grow specific plants. Besides, the light wavelengths required by different plants in different growth stages are not the same. 

It is crucial to match different plants to maximize planting efficiency. That is why you should select the most suitable LED grow lights based on the growth characteristics of the plants.

In addition, you must also take into account the size, number, and density of plants. From there, you can analyze and opt for the best lighting scale, and quantity of LED grow lights required.

8. Ease of Use and Maintenance

In choosing the best indoor grow lights, consider ease of installation. For instance, some LED grow lights only require plug-in and mounting, and you can already start using them. Remember to use the proper circuit to prevent fire hazards and slow-growing plants.

It is also crucial to purchase adjustable LED grow lights for color, intensity, position, and height. 

You’ll be able to fine-tune them with minimal effort for different plant types and growth stages. You can learn how to use LED grow lights for indoor plants here.

We also recommend importing those with simple maintenance, like the LED grow lights. These lights can typically last 50,000 hours or above. Though higher upfront costs, you’ll find long-lasting lights with low maintenance. You can save more workforce and accessories, not to say other invisible costs like effort and time!
