Cheap LED spot capable of replacing a 50W Spot? This Spot GU10 to 24 LED SMD HB 5050 Warm White is protected by a slight opal polycarbonate lens (such as halogen bulbs). It works directly in 220 volts. The opening angle is 150 °more than 4x that of a conventional light bulb. This LED bulb consists of 24 LED SMD 5050 triple chip (triple core ) allows powerful lighting for low consumption of 5 watts and a light output of 50 watts. !!! Description Number of LEDs: 24 Origin of the LED: Epistar 5050 HB (16-17 lumen / LED) Temperature Color: Warm White 3200K ° (warm temperature identical to that of a Halogen Spot) Diffusion angle: 150 ° Consumption: 5W (real) Voltage: 200-240V (also available in 85V-265V) Type of radiator: large Fins in Pure Aluminum to facilitate the transmission of heat. type of protection: protective glass in slightly opal polycarbonate to reduce the glare phenomenon. Base type available: GU10, MR16 GU5.3 (12VDC) Lifetime: 35,000 hours S...

TRUTH ON LED TUBES There are LED tubes on the market using LEDs like DIP (5mm). This kind of tube that is found abundantly on the internet or at unscrupulous resellers, offers only poor performance. In addition, the DIP-type LEDs that are used are usually overvoltage to give you the illusion that the tube is illuminating. These have a greatly reduced service life. Tests performed by independent laboratories show that the white diode (white DIP 5mm) will have lost 50% of its luminous flux after 6000 hours!!! It is therefore far from 50,000 hours or 100,000 hours manufacturer. The best is to opt for LED SMD or Power LED based tubes. SMD and Power LEDs, which are more stable, offer a much more penetrating lumen output. After 50,000 hours. CAUTION FOR USE OF LED TYPE DIP 5mm With the experience we have accumulated over 4 years, we can share our expertise. Thus, faced with the proliferation of importers, distributors, installers or resellers of this type of tube, we want to wa...

LED technology The LED light source (light emitting diode) is more and more often referred to as "21st-century lighting". The LED lighting is an area where the market is growing rapidly as LED lighting has recently become an alternative source of lighting for traditional incandescent bulbs and fluorescent lamps. Compared to incandescent lamps (bulb type), LEDs have many advantages: they consume less energy and their life is much longer. Their small size, high light output, extreme reliability, low energy consumption and long service life all contribute to the widely held view that LEDs are the technology of the future for lighting. In fact, we can already predict the disappearance of the incandescent bulb, the European directives go in this direction. We also bet that the competition between compact fluorescents and LEDs will undoubtedly designate LEDs for the reasons that follow in this talk. Advantages of LEDs: Consumption is 1/5 to 1/10 lower than conventiona...

Lighting enters the era of nanotechnology Will windows and walls turn into illuminating surfaces at night with nanotechnologies? Probable! Many research teams - including CSTB - are participating in Luminosurf, a project that is likely to disrupt lighting techniques. In each of the tubes, solutions containing particles of different sizes, corresponding to blue, green and red. Lighting technologies are in full (r) evolution. While the disappearance of the incandescent bulb is already announced, as the low consumption lamps are in the process of democratization and that the LEDs just appear on the market, the CSTB is already thinking about lighting according to -tomorrow. Exit the bright spots. Place large illuminating surfaces at low luminance and no glare. "The research project in which we are taking part tackles the problem of lighting in a totally new way," enthuses Christophe Martinsons, head of the Lighting, Electromagnetism and Electricity team, " We see...
