Different plants need different spectra to thrive. When choosing LED grow lights, there are many characteristics that need to be considered. First, you must decide what you want to grow. Before deciding what to grow, you also need to consider the following factors before buying LED grow lights:
1. Efficacy of LED Grow Light
The efficacy of Grow Lamp, also called photosynthetic photon efficacy or PPE, is the output of PAR (photosynthetic effective radiance) photons divided by the wattage of the lamp. The efficacy of the led plant grow lamp has quickly become one of the main indicators for buyers to evaluate products.
The higher the PPE, the better the effect of reducing power consumption, but this indicator also has its limitations. For example, PPE only considers photons in the PAR spectrum (not including wavelengths such as far-red light).
We do not recommend using photosynthetic photon efficacy as the only reference indicator for purchasing lamps. Because PPE does not include the spectrum effect, it cannot represent the quality of the luminaire.
2. Heat output of the LED Grow Lamp
In general, we recommend not to worry about the difference in heat output between LED lamps. But need to consider the advantages and disadvantages of the low-calorie situation.
In cold climates, some greenhouse owners find the heat emitted by HPS lamps more beneficial. This kind of heat does have certain benefits, but the lamp is not a reliable heat source because the heat is difficult to control. HPS grow lights will generate heat in various parts of the entire greenhouse, affecting plant growth in an uncontrolled way.
Controlling the heat can achieve better product quality. Commercial LED grow lights are the best choice, but if you want to use the extra heat generated by the lamps in a cold climate, regardless of other negative effects, you may need to look for more Multi-traditional plant growth lamp technology.
3. Easy to install
Commercial LED grow lights are installed above the plant canopy, and depending on the distance between your shed roof and the plants, you need to ensure that the grow lights can be easily installed and replaced.
In the greenhouse, most LED grow lights are installed on pillars running through the top of the facility. In indoor planting rooms, hangers, pulleys are usually used to attach to pillars, or to vertical plant racks.
Generally, it is smart to understand the manufacturer's installation process before buying. A good manufacturer must also have a well-thought-out system that is easy to install, replace and expand.
4. User Evaluation
Before buying a commercial Led Grow Light, it`s best to look at the company`s customer reviews. However, there will be some new starts, but a good company may not have too many business records. In this case, do not use performance as the only measure. They are most likely to bring you unexpected surprises.
If you decide to choose a new company, then based on the fact that they do not yet have a good transaction record, their offer must also have a reasonable discount.
5. Warranty
Nowadays, the standard warranty period for grow lights is generally 5 years. Some good quality companies only have a 3-year warranty. If you are going to make a large investment, you should consider reducing business risks through a warranty period that meets your business needs.
Some growers want to make quick profits instead of accumulating profits over the long term, so if this is the case, a lower upfront investment may make more sense than a longer warranty period.
