![]() It might not matter for your specific application, but understand that there are options for both mounting types. The last item to consider is the size of your fluorescent plugin lamp and how it is mounted – vertically or horizontally. Here is a chart showing all of the color temps: The 841 number is the color = 4100 kelvin (cool white). The first number 26 is the wattage = 26 watt. That should be listed on the side of the base of the bulb. Once you understand which type you have, you need to figure out what wattage and kelvin temperature you have. There are 4 options available: Single Tube (aka PL), Double Tube (aka Quad), and Triple Tube (aka Triple), as well as Single Tube Long (aka PLL). With the base type figured out, the next thing to determine is what specific compact fluorescent plug-in bulb you have. From there you can determine the exact base type you have by looking at the chart below:Īnother item to keep in mind when understanding your available energy-saving options is that 2-pin compact fluorescent have a magnetic ballast whereas 4-pin compact fluorescent have an electronic ballast. You will have either a 2-pin or 4-pin lamp. There are 9 common base types for plug-in compact fluorescents, but the easy way to narrow down what you have is to look at how many pins there are. ![]() The first thing to understand is base type. The available LED options for replacing compact fluorescent plug-in bulbs are following the same path as LED T8 Tubes.īefore we get into the energy saving options, it is important to understand what the current plug-in compact fluorescent bulb options are. ![]() Many commercial-grade LED PL lamps are now DLC rated, allowing consumers to get rebates for converting to LED. Given their popularity, there has been a huge focus on energy-saving LED alternatives to these plug-in compact fluorescents. Reading lights tend to be marked 5000-6500K these appear much bluer and perceived as brighter.Next to linear fluorescents, plug-in compact fluorescents are one of the most common light sources found in commercial buildings. For whiter light – more akin to daylight – good for kitchens and workspaces, bulbs labelled between 3500-4100K would be best. Incandescent bulbs are around 2700-3000K and produce a yellower warm/soft light, great for creating a relaxed ambiance. Light colour is measured using a temperature scale called Kelvin (K). Choosing the colour temperature of bulbsĬhoosing the right colour is dependent on the atmosphere you’re trying to create within your room, or what the space you are lighting is used for. Bulbs that are nearer to daylight (bluer or cooler in colour) sometimes appear brighter than yellower coloured lights. The colour of light can also affect how bright a light appears, even if the lumens are the same. Incandescent Bulb Wattageĭata sources: American Association of Physics Teachers 1996 and Energy Star 2016 What else can affect brightness perception? An equivalent compact fluorescents (CFL) bulb in light output (lumens) should consume only around 7 watts and LEDs approximately 6 watts. Wattage to Brightness ComparisonĪ 40 watt incandescent filament bulb produces roughly 460 lumens. Some of the most energy to light efficient LED bulbs are now reaching over 120 lumens in Energy Star tests. On average, an incandescent bulb produces around 14 lumens per watt, compared to 63 lumens for energy saving compact fluorescents (CFL) and 74 for LED bulbs. ![]() Most of us have a preconception of how bright a 100-watt incandescent bulb is even though this can vary tremendously between soft white and clear glass bulbs. Lumens is an accurate way of measuring the light output of bulbs – brightness is what we perceive, luminance is what we measure. They come in varying technologies, such as Compact Fluorescent (CFL), Halogen and LED and they last much longer – up to 25 years for LEDs!ĭefining the brightness, or light output of bulbs is changing from wattage equivalents to lumens. Nowadays, energy saving bulbs produce far more light, less heat, whilst consuming less energy (Watts). In recent years choosing light bulbs has become far more confusing – you knew roughly what you were getting with a 40, 60 or 100 wattage filament bulb. Household cost based on 12 bulbs.Įlectricity costs are calculated using the UK: Price Cap (Oct 2023) electricity rate of £0.27 per kWh (incl. *lumens conversion based on averages of Energy Star LED/CFL testing data 2016
