GL-E27-011 LED bulb is novel in design, significant in saving energy, convenient and practical, safe and reliable. The white LED light bulb is the most environment friendly and the most energy-efficient lighting source. One of the LED light bulb's notable features is that it can work at a temperature of 150 degrees environment. It uses high-power LED with characteristics of pure color, low in light degradation. LED tube light converts ac directly into dc, which is good for your eyes. It adopts non isolated constant-current built-in power supply and its advantages are that the circuit is simple in design and manufacturing cost is low. The source of white LED light bulb is formed by low-power SMD, and the luminous flux is fully guaranteed in the structural design to ensure the maximum lighting. The drive current of every LED chip is limited to the optimum operating current range to ensure the longer life. White LED light bulb will not produce noise, so it is a best choice for the library and/or the office. LED light bulbs do not contain mercury and lead, so they play an important role in environmental protection. The light source of LED spot light adopts the solid light source and the lifespan mainly depends on the solid LED light source and drive heat dissipation. At present, the lifespan of white LED light source can reach to 50,000 hours. The LED quantity of type is 14, the power is 7W and the input voltage is 85-265VAC. The color temperature options are 3000K, 4100K and 6000K for your choice. it is suitable for jewelry shop windows, shopping malls, meeting rooms, and exhibition halls.

LED light bulb lumens

We all know that the LED light bulb lumens is of great importance for a LED light bulb, but what does LED lumens mean?LED lumen is defined as follows: Energy radiated from a light source, per unit time, over wavelengths visible to the human eye. LED Lumen, abbreviated as "lm", pertain to the associated unit of measurement. Some people like to think of LED lumen as the overall visible light produced by LED lights. Most datasheets publish LED lumens at a pre-selected condition (referred to as the typical or test condition). This condition is a fair compromise between maximum efficiency and maximum LED lumens, since efficiency is lost as power increases. Datasheets will also provide a LED lumens rating at the absolute maximum allowable current setting. Ambient temperature (Ta) is one factor that can adversely affect LED lumens. The LED lumens will diminish as the temperature increases, as a result from the surrounding environment or thermal energy produced by the LED light itself. Modern LED lights are capable of producing an increased amount of total light over a broader area. The corresponding LED optics datasheet will publish a LED lumens (lumen rating), rather than a luminous intensity or candela rating.
