Even though LED has been in existence for quite some time, it is until recently that it has been acknowledged as a principal source for household lighting. While incandescent bulbs have been the standard for many years, they are currently being replaced by energy-saving surrogates such as the LED lights. However, the lighting switch may be complex to comprehend. This article will enrich your knowledge of LED Reflectors.
What You Should Know About LED Reflectors Directional Lighting
LED lighting is unidirectional. That is to say, it only emits light in one direction, unlike incandescent bulbs. The directional lighting is often termed as beam types or beam angles and will always show you the total area that will be covered by light. For instance, the full beam type extends to 360 degrees. However, other lights provide constricted beams of only 15-30 degrees, sometimes even less.
PAR and BR: Angles and Size
Generally, there are two types of LED light bulbs: Parabolic Aluminized Reflector (PAR) and Bulged Reflector (BR). The BR bulbs can illuminate an area of an angle greater than 45 degrees as a result of their wide flood beam angles. In contrast, PAR light bulbs can illuminate areas of angles between 5 degrees to more than 45 degrees. Suppose you want to determine the diameter of a bulb, simply take the values fixed before BR and PR then divide by eight. For instance, if you have a PRA 32, then the diameter of the bulb is 32/8, which gives 4 inches.
There are times you may wish to have a precise type of white color illuminating your room. Well, this has been an advantage of incandescent bulbs. Providentially, LED bulbs provide similar color temperature like the incandescent ones but saving much energy.
The Level of Brightness
While many reflectors measure the level of brightness in watts, the LED reflectors use lumen. The two measurement criteria are distinct. Watts quantifies the energy the bulb utilizes while lumen measures the exact illumination of the bulb. LED lighting wins the hearts of many because of using much less energy to offer the same quantity of brightness as an incandescent.
