![]() ![]() All-in-all, LEDs last longer than incandescent lights, save a lot more energy, and are a smart long-term investment in conservation. It may seem like a lot of information, but it’s best to understand what you’re getting with LED lighting before making a purchase. Make sure that you switch out bulbs of the same base before purchasing LED lights. ![]() The letter refers to the shape of the bulb or a special feature like the reflector type in the bulb. How are Light Bulbs Named Each light bulb is named using a letter and a number. The base of LED lights and incandescent lights sometimes are not the same. In this article, well explain how to tell different types of light bulbs apart and the differences between their sizes, so keep reading to learn more about this topic. The conversion from incandescent wattage to LED lumen rating for everyday bulbs include: What makes LED lighting so attractive is that it uses much less power to deliver the same amount of light as an incandescent. Watts measure how much energy the bulb uses, while lumens measures the brightness of the bulb. The brightness level of LED reflectors is measured in lumens, not wattage. Luckily, LED bulbs offer the same color temperature as incandescent light bulbs but do so without using as much energy. Sometimes you want a specific type of white color lighting a room. LED Light Optics - Beam Angle, Lens Type, Reflector Type Projected Light The projected light from an LED bulb is affected by a number of factors including: Total downward luminous flux (Lumens) Beam angle as per the lens Lens type Reflector type We have discussed the concept of the quantity of light produced by the LED luminaire elsewhere. For example, the size of a PAR 30 bulb is 30/8, or 3.75 inches in diameter. To find the diameter, just divide the number by 8. Incandescent bulbs are the most common type of light. ![]() The numbers after BR and PAR (like 30) represent 1/8 th of an inch, which is the diameter of the bulb. Halogen Bulbs operate by using an electric current to heat a filament. PAR light bulbs range in angles from 5 to over 45, specifically: There are two types of LED light bulbs: Parabolic Aluminized Reflector (PAR) and Bulged Reflector (BR).īR light bulbs have “wide flood” beam angles, meaning they light an area at an angle higher than 45 degrees. Some lights offer narrow beams, such as 15-30 degree beams or even less). Simply put, this tells you the how much area the light will cover (e.g. This directional lighting, referred to as “beam types” or “beam angles,” is described in degrees. LED lighting is more directional, emitting light in only one direction. LEDs offer somewhat of a spotlight compared to incandescent bulbs and compact florescent light bulbs (CFL). To make the lighting switch a little easier to understand, here are five factors to consider when choosing LED reflectors. Incandescent light bulbs - those inefficient, energy-sapping bulbs that have been the standard for years - are on their way out and quickly being replaced with energy-saving alternatives like LED lights. The light-emitting diode, or LED, has been in existence for a while - your digital clock and flashlight have been using it for years, but only recently have LEDs been considered as the primary source for household lighting. ![]()
