How to Choose a Spotlight to Illuminate the Yard

Current owners of country houses often choose to illuminate their yards the powerful spotlights, allowing maximum light the local area and scare off intruders. What kind of spotlight is best suited for this purpose?

There are four types of spotlights - halogen, metal halide, sodium and LED. The basis is a halogen incandescent spotlight with buffer gas added to the cylinder, which makes this product a high-temperature lighting device as its spirals working temperature can reach 3000K. Metal projectors operate based on the high-pressure discharge lamp, the burner which is metered radiating additive, adjusting the spectral characteristics of arc discharge mercury vapor. BTW, you can select the spotlights at Banggood. Besides, you can easily get other lighting (e.g. USB touch sensor) there with high quality and reasonable prices.

Metal, sodium and halogen luminaires, unlike LED spotlights (e.g. color changing led flood light) are unstable vibration. The light source in sodium floodlights are the sodium high-pressure discharge lamps. During the gas discharge glowing heat occurs in sodium vapor, which leads to a monochromatic radiation. The light source in LED spotlight consists of environmentally friendly LEDs do not contain mercury components. Experts do not recommend to buy the first got the spotlight, and the first to evaluate the work of the type of lamp, which is a priority in the selection of the lighting device.

Halogen spotlights have excellent luminous efficacy and color rendering, as well as targeted lighting certain areas of the yard. They offer high performance, made of tempered glass and operated at a high temperature without any problem. Sodium units provide a bright yellow-orange light due to the prevailing sodium light, but when illuminated give unsatisfying color reproduction. Sodium floodlights advantage is their versatility, which allows to combining the device with other light sources.


Floodlights with poor color rendition are commonly used for lighting of industrial buildings or street lighting. Metal halide units allow cool bright light and have a high color rendering / light output. They are extremely reliable due to the resistance to voltage drops, as well as protection against dust and moisture, so metal halide lamps are perfect for lighting the yard. However, the most high-quality option is LED spotlights (e.g. LED PIR spotlight), which are completely made of strong and durable high quality materials. They provide precise directional flow of light, instantly turn on and are stable even at low voltage network.
