20W corn light E27 LED lamp 4000K IP64
80% more energy saving compared with conventional light, CFL, Incandescent light; replace 400W halogen/150W CFL bulb by only 45W;
Input voltage: AC85-265V; 140pcs Super bright 5730 SMD LED chip as light source, 4500lm, 360 degreee beam angle. No Ballast Required (Remove/bypass the ballast);
With aviation aluminium heat sink, ABS housing good corrosion resistance, energy-saving, low power consumption, longer lifespan, less lumens depreciation;
No uv or IR in the beam, Instant start, No flickering. Special surface design with arc, make sure the radiation diameter on the ground is accord with the standards for size;
Q: Why do LEDs use such little power?
A: LEDs do not use a filament where a conductor is heated and light is created. Filament based lighting consumes more power than the light produced. LEDs produce very little amounts of heat and do not use filaments making them far more efficient in consumption and output.
Q: What LED type you use?
A: At present,the led spot light and LED track light, often use COB LEDs;
The led corn light, LED globe bulb usually uses SMD 5730 LEDs and SMD2835 LEDs.
The LED panel light and LED tube light, always use SMD2835 LEDs.
LED high bay light uses SMD3030 LEDs.
LED flood light uses integrated COB LEDs or SMD 5730, SMD 3030 chips.
Q: What is the color of light LED’s emit?
A: White light LED’s can be manufactured in a range of white colors. White light is measured on the color temperature scale in degrees Kelvin. White LED’s are typically grouped into 3 categories: A. Warm White: Typically 2700-3500 K. This most closely matches the color of incandescent light and is the color of white light most used in the home to create a warm atmosphere. It has an underlying tone of yellow/orange. B. Natural White: Typically 4000-5000 K. This color of light is brighter white and does not have a yellow component feeling. Natural white light is typically used for office, retail, basement, or workshop lighting environments. A traditional fluorescent tube light normally emits light in this range. Also metal halide lamps normally are within this range. C. Cool White: Typically 6000-8000K. This color of white light tends to have a bluish tone. Lights in this category are typically used in manufacturing and high brightness environments.
