Compact Fluorescent Lamps (CFLs) are energy-saving replacements for incandescent light bulbs. Below you will find information to assist you in choosing the right bulb.

BudgetSorb is ideal to use on hard surfaces wherever coolant, paint, oils, fuels, mild chemicals and general liquids are stored, handled and spilled.

Less common than the E26 or E12, the E17 base is typically used in specialty fixtures like appliance lights and desk lamps.

The GU10 base features two pins that lock into place with a twist. Commonly used in track lighting and recessed downlights.

Unlike incandescent bulbs, with LED bulbs you have the option to choose the color temperature of the light. This is measured by a Kelvin scale where lower numbers mean yellow candlelight and higher numbers mean blue daylight. See chart:

How do incandescent bulbs and CFLs compare? Incandescent bulbs produce light by passing electricity through a small wire filament, heating it until it glows. Compact fluorescent lamps use an efficient chemical reaction to produce light, which requires 66%-75% less electricity to produce the same light output as a comparable incandescent bulb. CFLs are also cooler than incandescent bulbs and last considerably longer. CFLs are available in a familiar range of styles and colors to suit different applications, including standard round, candelabra, flood, track, three-way, dimmable, indoor, and outdoor.

Similar to the E26, the E27 base is common in Europe. While almost identical in size, it's essential to ensure your fixture can accommodate this slightly different base.

MR16 bulbs use a bi-pin base and are often found in accent, track, and recessed lighting. They are popular for their focused beam and compact size.

Another fact to keep in mind is the dimming capabilities of those LED bulbs. Not all of them are dimmable, unlike the incandescent Edison Bulbs. The ones that are dimmable are restricted to certain low-voltage dimmers specifically designed for LEDs. There are also limitations to the amount of bulbs each dimmer could handle. The older standard dimmers will most likely not work properly on most Filament Edison LEDs.

Understanding the differences between light bulb bases can help you choose the right one for your fixture. Here’s a quick comparison:

The E26 base is the most common in the US, also known as a standard light bulb base. Widely used in incandescent, LED, CFL, and halogen bulbs, this base fits most household fixtures from ceiling lights to table lamps.

If you have a light fixture with an E17 intermediate base light socket and you are having a hard time finding the right bulb or would like to use a more common light bulb, you can get an adopter which will enable you to use the E12 candelabra bulbs or the medium E26 base bulbs.

BudgetSorb is an absorbent floorsweep which absorbs oils, fuels, coolants, degreaser, mild acids and caustics, paints, solvents and most mild water-based chemicals.

What are the different base types of compact fluorescent bulbs? CFLs are available in three base types: screw base, pin base, and GU24.

How long do the bulbs last? CFLs can last 8,000 to 15,000 hours depending on quality while incandescent bulbs typically last 750 to 1,000 hours. What types of lighting can I get with CFLs? While many people are familiar with the bluish-white flicker of a hospital hallway illuminated by old-style 48-inch fluorescent bulbs, in fact a broad range of colors are available. The common colors range from a "soft white", to a medium white to a "daylight" color that has more blue and less yellow. Additionally, a range of novelty colors are available (red, black, green, etc.) including yellow, which is ideal for outdoor lighting as it does not attract insects. For indoor lighting of living spaces, choose a cooler temperature light, while for garages or work areas use the brighter and bluer daylight CFLs which cast a wider area of illumination. If you are using a dimmable fixture, you will need to purchase a CFL specifically designed for dimming; standard CFLs do not have that function. How do I dispose of CFLs? Some municipalities allow for regular trash disposal while others require disposal at a hazardous waste facility or recycling facility. Contact your local waste collection service or municipality for the policy in your area.

When choosing an LED bulb it’s important to understand lumens (light output). Until LED bulbs came we were looking at wattage to know how much light the bulb would give out. With LED bulbs this does not work. We have to look at lumens to know how much light the bulb will give out. To make this transition easier many manufacturers will list the wattage equivalent on the bulbs specs. For example, a 5-watt LED bulb may be labeled as a 60-watt equivalent.
