LED Indoor Grow Lights Buyer’s Guide

Due to the fact that LED indoor grow lights are relatively new in the gardening marketplace, many people still have questions when it comes to selecting the perfect grow lights for their particular situation. Below we hope to answer some of those questions by outlining some of the technical and non-technical characteristics you should look for—and the factors you should consider, before purchasing these products.

Adjustable Output Spectrum

Because LED indoor growing lights are often sold with different color LEDs, you require a lighting solution that will allow you to dictate the light output spectrum based on your choice of plants or seasons. For instance, you can match colors to the flowering season, or to spring or summertime. By changing and varying the light output, you can simulate the seasonal light changes to match the growing cycle of the plant.

Cooling System

When purchasing high-powered LED indoor growing lights, those LED fixtures are going to require cooling, just as your computer at home needs a fan that cools it when in operation. Because of this, always look for lighting solutions that have a heat sink and a fan for cooling purposes. Since the LED fixtures do not radiate any heat, they have a metal pad that provides the way for the heat to leave the LED.

Metal Core Printed Circuit Board (MCPCB)

Although it sounds very technical, when shopping for LED indoor growing lights make sure those lighting systems are mounted on a metal core printed circuit board, or MCPCB. You can usually find this information out on the box, but if not, ask the salesman. MCPCBs are preferred in LED indoor growing lights over normal device circuit boards due to the higher than average levels of power on the LEDs.

Circuit Board Mounting

You will want to make sure that your LED indoor growing lights have a circuit board that is mounted to a larger than average heat sink—one with several fins. With more fins, the MCPCB has the ability to spread the heat out faster to aid in the cooling of the system. This is crucial to prevent the failures that are often caused by single fins—failures that can lead to overheating and damage to the LED indoor growing lights.

Constant Current Driver Circuit

When purchasing LED indoor growing lights you should strongly contemplate the electronic current circuit that powers them. The job of the electronic current circuit, or the driver circuit as it is technically known, is to convert AC power to direct current within the proper voltage and current level that the LED fixture can sustain. A proper LED circuit driver should supply a constant supply of direct current and regulate the intensity according to temperature changes.

Other Features

You should also consider other non-technical factors, such as the size of the garden you are planning to light, adjustable modes and lighting brightness, and the energy costs of the system you plan to purchase, among other factors

The Benefits of LED Indoor Growing Lights vs. Other Lamps

Compared to other types of lamps, LED indoor growing lights allow for:

• Space-Saving Designs. Other types of grow lights need a lot of space in the room and at the same time they will need more equipment to help them run smoothly. With LED lighting solutions, you can enjoy better space utilization, as they are smaller and do not occupy a lot of space in the grow room.
• Optimized Light Spectrum. LED technology allows the fine tuning of the light spectrum to create the best light that plants need to produce throughout their various stages of growth.
• Power and Energy Efficient. LED indoor grow lights are much more energy efficient than other types of lighting solutions.
• Long Lasting. LED indoor grow lights have the advantage of lasting thousands upon thousands of hours.
