Six key points in the selection of lighting products
When choosing a luminaire, why should I touch and disassemble the luminaire?
How to think about whether the various internal and external factors of the lighting meet the space?
What important information about the luminaire is to be recorded?
Comprehensive analysis and summary: Which lamp is most suitable?
touch
Why is it necessary to touch the luminaire when it is used? Because some features of the luminaire are the same as other products, if it is fine workmanship, feel comfortable, under normal circumstances, the quality of the product has a basic preference. Therefore, sometimes the approximate quality of the luminaire can be felt by touch.
Dismantling
Through the splitting and interpretation of the lamps, we can understand the installation and maintenance of the lamps, and compare which ones are more conducive to the future management and maintenance of the space.
Thinking
Consider the different characteristics of the luminaire and compare the functional requirements of the space.
Use time and operating expenses
Choose the right luminaire based on the time and operating cost of the luminaire.
Because the electricity cost saved by LED is about 85% of incandescent lamps, there is a long demand for lighting time, such as shopping malls, hotels, offices and other spaces, it is best to use power-saving lamps. For short-lighting time requirements, such as bedroom, kitchen and other spaces, according to the price and personal preference.
Below, we can understand from the "Lighting Basic Lecture Textbook" ((Social Lighting Association) statistics on the length of lighting usage and operating costs, you can understand why the selection of lights should also consider the use of time and operating costs.
Life and maintenance
Consider the factors that make maintenance difficult and easy, and choose lamps and light sources with long life and short life.
For example, in a relatively short space, and easy to replace the light source and maintenance, it is necessary to consider the quality and cost performance of the lamp. If it is in a high space, and even some of the high-altitude work vehicles are installed and repaired, it is necessary to consider the life and quality of the lamps.
Whether dimmable
Determine if the space requires dimmable luminaires.
Materials and lamps
Not studying the relationship between light and materials is not a good choice for lamps, because the same materials, different lighting effects are completely different.
For example: the same crack-fermented translucent glass (due to the transparent and reflective qualities of the glass), the light that appears in a single 1-watt LED linear lamp will appear partially bright. The light that shines through the fluorescent lamp (T5) gives a soft, even gradient.
Space height and lighting
From the direction of illumination of the light source, the luminaire can be divided into a down-illuminated type and a top-illuminated type. In the interior, the upper illuminating light is generally softer, while the lower illuminating light appears bright and direct. Therefore, when choosing a luminaire, in addition to personal preference, you should also consider the height and space of the ceiling, so that it does not cause pressure on the space.
recording
Record different information about the fixtures for easy comparison, contact and ordering.
Record the model number of the selected luminaire to facilitate product ordering; record the price of the selected luminaire product to ensure that the cost is within budget. (Confirm whether tax is included); record on-site test conditions and select suitable lamps.
analysis Summary
Finally, comprehensive analysis of the price, performance, quality and other factors of the lamps, in the comparison to help the owners choose the best cost-effective lamps.
