What to Consider When Purchasing LED Lights
Due to innovative technology, lighting solutions have been improved through the creation of LEDs. Unlike fluorescent and incandescent bulbs, LEDs are used mostly for directional lighting. This makes them suitable for concentrated light illumination purposes. Therefore, they can be very useful for domestic applications. If you are a homeowner wondering which LED light is best for you, below are some factors you may want to take into account before buying one.
All directional lights emit light energy in a conical shape. The candlepower intensity is usually greater at the centre of the cone and diminishes outwards. According to ColorVerse, "the beam angle refers to the angle between the two planes of light where intensity is at least 50% of the maximum intensity at centre beam." For outdoor purposes, it is best to purchase an LED with a wider beam angle for more light illumination. This is especially important for security light. For indoor purposes such as reading lamps, LEDs with smaller beam angles would suffice for narrowed light concentration.
This refers to leakage current. LED lights with large leakage currents tend to be cheaper than those with smaller leakage currents. Despite being economical, large leakage LEDs have a shorter lifespan and they quickly burn out the light beads. In addition, they consume more electricity. Therefore, it is advisable to find a perfect balance between costs and the leakage currents. The best choice would be to acquire an LED that is affordable for your budget and has a lower leakage current.
Colour of the LED
You may want to purchase an LED light that has a steady wavelength that does not waver during usage. In addition, different-coloured lights use different amounts of energy. For example, a white LED may consume double the energy of a red LED. Apart from being more energy efficient, white lights have a softer touch on the eyes. Therefore, they tend to be less strenuous. This property makes them the best reading lights. For decorative purposes, you may want to buy different-coloured lights as you keep their energy consumption in mind.
Texture of Lens
The texture of the lens plays a major role in colour mixing. LEDs with a textured surface or frosted coating will create a wider field angle and better colour mixing. The frosted coating on the lens not only improves colour mixing, but it also diffuses the light. This creates softer edges along the beam for a wider field angle and more spill. Therefore, for wider illumination, you may want to purchase textured lenses.
