For reading, is an LED light or lamp the best?

Any bookworm knows that adequate lighting is one of the key factors in creating the perfect spot to sit and enjoy a good read. A proper reading light not only makes it easier to see the page – it can also reduce eyestrain, which is healthier for your sight .
Here are some of the things to look for when picking out a reading lamp: When considering a reading light for your space, you should look at the complete lighting scheme of the room to determine how much light you need. If your reading light is going to be the sole source of illumination in the room, you should opt for brighter and more ambient lighting. On the other hand, if your space already has other lighting, a more focused lamp should give you the extra bit of brightness you need. Too much contrast between the page you’re reading and your surroundings can cause eyestrain.
Once you’ve established how much brightness you need from what type of reading lamp, it’s time to select the best type of lighting that can meet those needs.
There are a various light bulb options that offer a range of lumen outputs. However, the most often used for residential needs are fluorescent, incandescent and LED light bulbs, so we’ll focus on these particular types is LED .LED- LED light bulbs offer the brightest white light and will illuminate in a way that is closer to how daylight appears, making it easy to see every word on the page; however, it’s worth noting that the brightness of LED lights can cause a bit of glare if you’re reading a book with glossier pages.Bring all of these features together, and you have a reading lamp that provides the right amount and type of lighting in exactly the right place.
Now all that’s left to do is pick what to read .

In fact, high-quality incandescent lamp, CFL and LED are suitable for reading. The following are simple features of several lamps, for reference comparison ~
1. Incandescent lamp: incandescent lamp is the closest electric light source of natural light. Color temperature is usually between 2700K and 4000K. Since the frequency of the grid is 50HZ, much higher than the response of the human eye, and the filament is ignited to the cooling for a period of time inertia, so in the case of power grid stability, strobe can be ignored ~!
The advantage is that the color is good, and the theoretical value is close to 100, so that the original color of the object can be perfectly restored
The disadvantage is power consumption, photoelectric conversion efficiency is low, life is short, containing infrared and UV
P.S: halogen lamp is an advanced version of incandescent lamp. It is filled with halogen gas in vacuum bubble, which realizes the halogen tungsten circulation between filament and gas, greatly prolongs the life of filament, and perfectly inherits the color rendering of incandescent lamp
2. Energy-saving lamp: CFL (compact fluorescent lamp, the lamp is the actual domestic energy-saving lamps are a little scientific...) CFL is a great invention in the field of electric light source, can be made of any color characteristics and color is high, because the effect of glow fluorescent powder, strobe can be ignored (too low when the temperature is a problem).
The utility model has the advantages of high light efficiency, such as that the 11W of CFL can completely replace the incandescent lamp of 60W, and the color rendering ability of the CFL of the three primary color phosphor powder can reach more than 80, and some high-end products can reach more than 90
The disadvantage is fluorescent tube is filled with mercury vapor, how green manufacturing and recycling is a big problem, some responsible manufacturers use mercury pills in the tube (ha ha, on suspicion of advertising), partially solved this problem...
P.S: energy-saving lamps are relatively easy to buy at this stage of the market cost-effective light source
3. because the LED:LED light-emitting principle, eliminate stroboscopic and has high light efficiency and the pursuit of higher efficiency potential
Has the advantages of small volume, no flicker, no UV, high light efficiency, using high quality chip (OSRAM, Nichia, CREE) the product color can be more than 80 or even 95 and has a very long life
The disadvantage is the current national standard yet, the product on the market confusion, most manufacturers use inferior chip lead color less than 50... And because of the use of electric drive led to poor LED chip power supply problems are different, the chip array brightness difference and flicker.
In short, it is better to read with halogen light sources if you are conservative and do not care about lighting;
Please use care energy-saving energy-saving lamps, but must pay attention to the choice of the big, because small manufacturers use halogen powder phosphor color index less than 70 of the same, not suitable for reading;
If the pursuit of high-end, harsh energy-saving, hope longevity and non-traditional light source modeling, you can choose LED products, but it is best to choose the lighting industry's top brands and formal channels, so as to ensure product quality.
