How many watts of energy-saving lamps are suitable for reading?
Energy-saving lamp is actually a compact fluorescent lamp with its own ballast, which only consumes 1/5 to 1/4 of the electricity consumption of ordinary incandescent lamps, which can save a lot of lighting power and costs, so it is called energy-saving light. Nowadays, most people will consider this kind of lamps, so how many watts of energy-saving lamps are suitable for reading? If you like to read books, you need to pay attention. Below, Benwei lighting will explain it for everyone, let's take a look.

How many watts of energy-saving lamps are suitable for reading?
Energy-saving lamps, also known as energy-saving bulbs, electronic bulbs, compact fluorescent lamps and integrated fluorescent lamps, refer to lighting equipment that combines fluorescent lamps and ballasts (ballasts) into a whole. In 2008, the country launched the "green lighting" project, and urban and rural residents and enterprises enjoy a certain percentage of subsidies for using energy-saving lamps from winning bidders. The promotion of energy-saving lamps is of great significance, however, the environmental hazards of waste energy-saving lamps have also attracted attention. By the end of October 2012, hundreds of millions of energy-saving lamps have been scrapped in the energy-saving promotion project, each of which can pollute 180 tons of water and 56 acres of soil. The disposal and recycling of waste energy-saving lamps has caused concern. Despite this, people's demand for energy-saving lamps is still growing, especially in the just approaching 2015, the demand is still increasing.
Energy-saving lamps are compact and small in size. The luminous efficiency is high at 60Lm/w, and the power saving is more than 80%, which saves energy. Can directly replace incandescent bulbs. Longer life span, 6-10 times that of incandescent lamps. The inner wall of the lamp tube is coated with a protective film and the use of a triple spiral filament can greatly extend the service life. It can reduce heat release and save electricity.
Energy-saving lamps can be divided into two categories: self-ballasted fluorescent lamps (electronic energy-saving lamps) and single-ended fluorescent lamps (PL plug-in energy-saving tube lamps).

In fact, the energy-saving lamp is too strong and white. It is dazzling to read under such light for a long time, and some have strobe. It is only energy-saving, but it is not suitable for long-term reading. It is better to be placed in the hall. Incandescent lamps are most suitable for Reading books, 15W is a bit small, 40W is a bit big, 25W is just right. If there is a dimmable, it will be adjusted according to the fatigue of the eyes. Don't be afraid of the electricity bill, the eyes are the most important.
Reading requires relatively high illuminance, and the amount of correction depends on the age of the reader. Generally speaking, the minimum illuminance on visual tasks (ie books, magazines, etc.) is 400 lux. For detailed work or hobbies such as sewing and carpentry, bright white halogen lighting is the right choice, it will reduce eye fatigue. Wrong lighting can tire people who have been in front of a computer screen for a long time. To ensure that there is enough overhead lighting to illuminate the keyboard area, to avoid glare and screen reflections. The lamp should be angled away from the screen to avoid tiring reflections. In order to create a brighter light in a special area of the room, such as for reading, try to use a halogen bulb with a shade, which will provide direct light where you need it, without destroying the atmosphere of the room. The halogen-like lamp is suitable for conventional lamp accessories, and the luminescence is the same as that of the halogen lamp. So you don't need to buy special accessories to enjoy the benefits of halogen lighting. Traditional floor lamps or standard lamps are simple and excellent. It provides ample upward light (ambient lighting) and allows comfortable and detailed reading.
Energy-saving lamps
The above is an explanation of the question of how many watts of energy-saving lamps are suitable for reading. I believe you should have more understanding after reading it. The content is for your reference only, and I hope it can be helpful to you.
