The colour temperature of the lamp can be varied by using different types of phosphor coating. An electronic ballast is also required to limit the current in the circuit and prevent damage to the lamp. In the case of fluorescent tubes and most commercial-type fluorescent lamps, the ballast is added to the lamp externally, in the circuit or built into the fitting. For most compact fluorescent lamps, the ballast is built directly into the lamp in its base.
This allows CFLs to be used as direct replacements for classic incandescent lamps in the same fitting. In comparison, CFLs give off less heat and use much less electricity while maintaining the same amount of light as incandescents. Compact fluorescent light bulbs also last much longer than incandescent bulbs. This means that CFLs can help you save on electricity costs, replacement bulbs, and time and effort. For an even longer lasting bulb, consider buying LEDs.
Just as beauty is in the eye of the beholder, the quality of the light from any light bulb depends on who is using the light, how they are using it, and how they like it. Some people like clear bulbs in some applications, while others prefer a softer light.
Different CFL bulbs produce shades of light. Lower numbers mean the light has a softer, cooler, more yellowish colour. Most CFLs offer soft or warm white light at K to K, which is comparable to incandescent bulbs.
These bulbs work well in most home settings and enhance warm colours. In contrast, higher colour temperature lights emit a white to bluish-white light. If you need clean, soft illumination for the kitchen or bathroom, a cool white K— K CFL is a good choice. And for reading areas and workspaces that require more light, daylight K — K CFL bulbs cast a bright, cool glow that is ideal for detail-oriented activities. Look for higher colour temperatures where you would like a bright light, but consider opting for lower colour temperatures in other locations.
The amount of mercury in a low-energy CFL bulb could fit on the tip of a ballpoint pen, but because of its hazardous nature, used low-energy bulbs need to be recycled rather than put in the bin. All CFLs should be treated as hazardous waste and should not be disposed of in the bin.
All local councils have an obligation to make arrangements for the disposal of household hazardous waste at a civic amenity site or household waste-recycling centre.
For technical reasons, the glass used in the manufacture of household energy saving light bulbs has to be opaque, not transparent like the glass that is used in many traditional incandescent bulbs. Many CFLs will last for 8,, hours of use. This is significantly greater than traditional incandescent bulbs, which often last for less than 1, hours. You can extend the life of your CFLs by leaving them on for at least 15 minutes at a time — turning them off and on frequently will shorten the life of the bulb.
Energy use is measured in watts, but light output is measured in lumens. Simply put, the more lumens, the brighter the light. Because CFLs are so much more efficient, they use less energy watts to produce the same amount of light lumens. A non-integrated ballast is the type of CFL technology that we typically call a "plug-in. This is similar to linear fluorescents but is far smaller than a linear ballast.
The integrated ballast CFLs are created to replace incandescent and halogen lamps. Literally, take out the incandescent or halogen bulb and put in a CFL bulb in the same socket.
BUT, do incandescent and halogens need a ballast? So, in order for these CFLs to work in a regular medium base screw socket, a ballast has to be integrated into the CFL. The most common reason people use compact fluorescent bulbs is to save energy. However, there are some other applications for these lamps that you see quite often. Recessed cans are used in both hospitality and residential setting.
It's common to see K CFLs used quite a bit in these cans. Bestselling Chandeliers and Pendants. Sign In. Join as a Pro. Houzz TV. Houzz Research. Shop Featured Holiday Categories. Home Decor. Holiday Decor. Christmas Trees. Holiday Lighting. Gift Cards.
Electrical Wiring. CFL in a shower? Email Save Comment Sort by: Oldest. Newest Oldest. Hi, I have done this in a shower with a recessed can. Like Save. Related Discussions Led lighting from fluorescent Q. Are your can lights the CFL where it's really just a pigtail light inside a globe? If the recessed light is over the shower and has a lens, typically, the highest incandescent is 40w and is awfully dim. If you go with LED conversion, get a k kelvin. That mimics an incandescent bulb and they are rated for a wet location.
I do not think you will be disappointed with it as long as it is not on a dimmer. Good luck! Fixing a dark shower without hardwiring Q. I agree with making sure that the bulbs in your existing light fixture are "daylight" not soft white New CFLs, being lower wattage, allow you to go up in brightness without compromising safety.
After that, how about a couple of strategically placed mirrors to bounce light around? Large vanity mirrors are more expensive, but if you have wall space, you could find inexpensive portrait sized mirrors in frames, paint the frames a light colour that works in your space, and hang a grouping that's positioned to catch light and bounce it toward the darker areas?
Also a fresh coat of bright white ceiling paint might help. I pinkmountain: Excellent post and so true. If one person does one thing to save energy consumption, and other one does one thing and another and another, it's amazing as to how much humans can do to create a positive world rather than a negative one. Hallways and closets: CFLs do best when they are turned on and left on for at least 15 minutes. Repeated ons and offs shorten their lifespan.
Most of the time, we turn on the hallway or closet light for only a minute or two. These are more good places for LED lights. LEDs or halogen lights will probably do better in these situations. It will have an extra protective coating to keep it better insulated from the frigid temperatures. No matter which bulb you choose, make sure it fits the lamp you need it for. For example, only place a CFL bulb labeled for dimmable or three-way use in a lamp of that type.
