People said that knowing one’s situation and that of the enemy grantees victory in every battle. It is advisable to learn about something before you take action. Prior to buying LED lights, you need to make it clear about their benefits as well as weaknesses. However, in the first place, we should have an intimate knowledge of two terms, Wattage and Lumen. Wattage refers to the measurement of electricity power, the more watts a light is, the more power it consumes and more money you pay for. Lumen is a letter to describe the degree of brightness, the more lumen the brighter. Usually, people define the light’s efficiency as the level of brightness achieved per watt.

Compared with traditional illumination, LED lamps own some advantages. Firstly, they consume less energy that ranging from 0.83 to 7.3 Watts. Secondly is that LED bulbs have a long life span lasted for 50,000 hours. Thirdly is durable since LED lamps are resistant to vibrational shocks, and they are ideals for applications that need to turn on and off frequently as they can keep working from minus 40 centigrades to 185℃centigrades. Fourthly, LEDs contain no mercury so they are safe and environmental friendly . Fifthly, the light of LED lamps is not ultraviolet and would not attract bugs in the open air.

Every coin has two sides. LED lights are very heat sensitive, any excessive heat or inappropriate applications could affect the output and narrow the lifespan. At present,, LEDs are more expensive than conventional lighting technologies, that is a problem many salesmen have to face to. LED lamps typically cast light in one direction at a narrow angle so if you want to broaden the beam you need to with the help of lenses or reflectors.

There are a lot of factors you need to take into account, such as the angle of lighting, the level of focus, the way how it will be used, the place where it is going to installed and the accessories for bulbs. The related integrated circuit is DRV101F, which is designed as one kind of PWM solenoid or valve driver device that is available in 7-lead staggered TO-220 package and a 7-lead surface-mount DDPAK plastic power package. It also can be used in wide range of applications such as solenoid or erheat protectors, fluid and gas flow controllers, part handlers, electrical heaters and coolers and motor speed controllers, as well as industrial control.
