LED light - reduce energy with LED lighting

Explosion proof Floodlight IEC Specs

There was RFQ for LED lighting with spec as follow:

LIGHTING LAMP
TYPE : FLOODLIGHT LAMP
BULB : LED
WATTAGE : 100 – 150 WATT
INPUT VOLTAGE : 90 – 260 VAC
COLOR : WHITE (5000-7000K
INGRESS PROTECTION : IP 66
EX PROTECTION : EX II 2G IIC T6
APPROX : WEIGHT 7 KG
C/W MOUNTS & ACCESSORIES : SLIPFITTER
CROSS ARM MOUNT, WALL/PIPE BRACKET,
WALL BRACKET, TENON FITTING

As I indicate the spec refer to some brands.
I try google ti with narrow search option with indicate Input Voltage 90-260 Watt with results very major.
I assuming this specs are China brand.

Try to propose to Dialight safesite floodlight with specs as follow:
SafeSite Flood Light, ATEX, Medium, 12500 lumens, 112 Watts, 100-277V AC, Cool White, Glass lens, Hydrogen Environment, Junction Box, PN: FLH9MC4GNJNG.

Light-emitting diode (Basic Knowledge)

noreply@blogger.com (Unknown) — Tue, 15 Apr 2014 03:33:00 +0000

A light-emitting diode (LED) is a two-lead semiconductor light source that resembles a basic pn-junction diode, except that an LED also emits light.^[7] When an LED's anode lead has a voltage that is more positive than its cathode lead by at least the LED's forward voltage drop, current flows. Electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

An LED is often small in area (less than 1 mm²), and integrated optical components may be used to shape its radiation pattern.^[8]

Appearing as practical electronic components in 1962,^[9] the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible,ultraviolet, and infrared wavelengths, with very high brightness.

Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs. They were soon packaged into numeric readouts in the form of seven-segment displays, and were commonly seen in digital clocks.

Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are now used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, and camera flashes. However, LEDs powerful enough for room lighting are still relatively expensive, and require more precise current and heat management than compact fluorescent lamp sources of comparable output.

LEDs have allowed new text, video displays, and sensors to be developed, while their high switching rates are also useful in advanced communications technology.

Guidance LED Lightings for home use

Choosing an LED light bulb

Many different models and styles of LED bulbs are emerging in today'sthere are Mercury Lux, Alive Energy, Lptronics bulbs , Kingsun. When choosing a bulb, keep in mind the following:

• Estimate desired wattage - read the package to choose desired illumination level. For example, a 3W LED is equivalent in output to a 45 W incandescent.

• Choose between warm and cool light - new LED bulbs are available in 'cool' white light, which is ideal for task lighting, and 'warm' light commonly used for accent or small area lighting.

• Standard base or pin base - LEDs are available in several types of 'pin' sockets

or the standard "screw' (Edison) bases for recessed or track lighting.

• Choose between standard and dimmable bulbs - some LED bulbs, such as

the Mercury Lux, Alive Energy, Lptronics bulbs, are now available as dimmable bulbs.
