Compact fluorescent lamps or CFL grow light bulbs can be used for growing indoor plants. A CFL grow light is of great help to growing plants because it provides the color spec…trum which a plant needs to flourish. Using CFL grow light bulbs, however, has its pros and cons. Advantages of CFL Grow Light Bulbs: CFL grow light bulbs are cost efficient. These bulbs are cheap and easy to find. A 60-watt bulb only costs a little over $10 on Amazon. You can also save on power bills since CFL grow light bulbs are energy-efficient as well. CFL grow light bulbs use 50% to 80% less energy than incandescent light bulbs. Then, CFL grow light bulbs are very long lasting. Compared to incandescent bulbs, CFL grow light bulbs last longer. They can last for up to 10,000 hours, that is, more or less 13 times longer compared to the lifespan of an incandescent lamp. Another advantage is of CFL grow light bulbs is that they can fit into a standard light socket and do not call for any special lighting fixture. They are very versatile, and can be used to light up any area in your home. Dimmers are also now available for some CFL grow light bulbs, so that you can control their brightness. Disadvantages of CFL Grow Light Bulbs: Firstly, CFL grow light bulbs work best when used for long periods of time. Studies show that the more frequently you turn CFL grow light bulbs on and off, the more likely its life span will be shortened. Hence, this defeats their cost efficient and energy efficient advantages. Secondly, CFL grow light bulbs' performance may be affected by the temperature of their environment. Low temperatures can cause the CFL grow light bulbs to perform with lower light levels, hence reducing their utility. Lastly, CFL grow light bulbs contain mercury, which can be a toxic. The good thing is that it does not pose a health threat unless the bulb is broken. That is why there is a special way of disposing CFL grow light bulbs. You must know how to dispose of these bulbs properly and responsibly. You can learn more information about CFL grow lights through the brand's website or by asking the retailer. You can also find customer feedback online which will be helpful for you in making your decision of whether to use CFL bulbs or not for growing your indoor plants.
Overall, I would say that an intelligent lighting system is the best thing to go for - of course it depends what fixtures are on the rig. Intelligent lighting gives you a lot …more freedom in what you can do where as with traditional theatre lights and par cans you cannot easily change gobo, colour, rotation or position. A disadvantage could be that intelligent lights take up a lot of power and room and also you would need a specialised desk that can 'talk' to intelligent lighting fixtures. so to sum up: ADVANTAGES: - Easily change between colour, gobo and positioning - Intelligent lighting can be used for theatre and music (multi - purpose) - They are easily wired up (DMX) DISADVANTAGES - - Power consumption - Space - Price If you are thinking of kitting out a rig with lights, I would advise you to shop around and see what would suite your needs. Hope this helps!!
The advantages of traffic lights are; they control the flow of traffic making it easier for drivers and safer for pedestrians, they reduce the risk of accidents and they lower… the chances of traffic jams, etc.....
Advantages: easy to use, inexpensive (comparatively), can look at live specimens (but its kinda hard to do so), Disadvantages: cannot magnify over 2000 times, poor…er resolution (comparatively) ,
An advantage is that it allows you to see because the light reflects off an object and into your eyes. Visible light waves is the only electromagnetic wave you can see. It… allows you to see colors. A disadvantage is the amount of light pollution. Can hurt your eyes if u stare at it.
advantages- a brighter whiter light, more directional disadvantages-power hungry, create lots of heat, expensive bulbs, not very energy efficient.
The advantages of light sensors is that they are really good security systems. The disadvantage of them is that they're really easy to set off.
One of the advantages is that it allows you to see, because the light reflects off of an object and into your eyes. One disadvantage is the amount of light pollution when star…gazing. Advantage: Plant growth. Disadvantage: Sunburn.
-an advantage of a light sensor is that energy is being saved by the lights in whatever situation because they will only turn on when light is sensed. -a disadvantage is that… most sensors need an interface to convert analogue signals into the digital signals that a computer can understand.
One nice thing about light bulbs is that they provide light indoors and when it is dark outside, without having to light a candle or an oil lamp. They are also relatively safe…, clean and easy to operate. Disadvantages include the fact that you will need electricity and wires that are properly installed and cannot be easily moved about. It is also difficult to repair a broken light bulb or one that has burned out, and they must be disposed of and replaced.
The disadvantage are that it can cause skin cancer if you are exposed to sufficient amounts of UV light (in particular, UV-B and UV-C light). See the Related Questions link to… the left of this answer for more information about that: "How do UV-B rays affect people?" One of the beneficial uses of UV light are that it can be used to kill bacteria and other microbes. It is commonly used to purify water for instance or clean things. UV light can also be used for a variety of other of application, such as black lights (which just look cool!). Also many compounds fluoresce (they emit light) when exposed to UV light. This is how forensic scientists can find traces of blood and other bodily fluids at crime scenes for instance. Finally exposure to some UV-B light causes the body to make Vitamin D, an important nutrient. While some exposure is important too much will cause sunburns and possibly cancer.
Street lights help pedestrians to walk safely after sunset. The car drivers find it convenient to drive smoothly,as driving in a highway without street light is a nightmare. W…ell, the hellogene lights emits particles that are injurious to eyesight and human skin. On the humourous note, street lights cause inconvenience to those who commit highway robbery and darkness is the precondition to their professional job !
-Compact fluorescent bulbs use 66% less energy than a standard incandescent bulb, and last up to 10 times longer. -A 32-watt CFL can save a homeowner $30 in energy costs over… the life of a bulb. -Lower weight and size, has a more attractive shape. -Easier and less frequent replacement. -Less maintenance cost.
