Ballasts for lamps and LEDs Fluorescent tubes, as well as other types of discharge lamps, are not suitable for direct connection to the power grid. The ballasts are then used in combination with the starters to light the lamps. Conventional fluorescents and discharge lamps do not work without ballasts and must always be connected to them. For fluorescent tubes, the third generation of ballasts is currently used. Also know that even with LED technology, we also use "ballasts" called drivers in this case. In general, there are 2 types of ballasts: ·          Conventional ballasts, and the economic version ·          Electronic ballasts Conventional ballasts: Since 2017, only energy class A2 ballasts are installed. For the next few years, conventional ballasts may no longer be sold in the EU because they do not meet the growing requirements for energy efficiency. Like incandescent ...

How to install an LED tube? Installing a TL LED tube is very easy. All LED tubes are plug & play, which means you can easily install them yourself and replace your existing TL tubes. If you are in doubt about whether to do it yourself or not, contact a certified installer. Comply with the rules for electrical equipment installations in your country. Here are the 4 steps to replace your current TL tube with an LED tube: Step 1. Make sure the switch is in the off mode. Before replacing a bulb, the switch must be turned off. For added security, you can turn off the power at the electricity meter. Step 2. Turn the fluorescent tube a quarter. In this way, the LED the tube comes off the installation and you can remove it. Step 3. Take your new LED tube and fit it into the installation with one end of it. Next, turn back a quarter until you feel the tube is installed and fixed. Step 4. Turn on the power and start saving...

LED lighting for museums For museums, the use of LED lighting is more interesting from day to day . In fact, works of art must be kept in a cool, dry place in the dark to protect them from damage. However, to ensure that museum visitors continue to enjoy the works, the ideal lighting is needed. Lighting in museums should always serve two purposes: 1.        General Illumination - Sufficient brightness throughout the room 2.        Accent lighting - accentuate brightness on different works/objects Which LED lighting for museums? Showcase lighting Some objects can be exhibited in showcases with appropriate lighting. For windows without their own illumination, the ceiling lighting should always focus on the window, to prevent any reflection. In addition, it is recommended in this case to use anti-reflective lenses and dimmable (dimmable) lights. Ceiling lighting. Lighting for objects Som...

High bay LED vs. HID / HPI high bay The discharge lamps are used for warehouses were factories. With this technology, light scattering and color rendering are weak and inefficient in the long run. In addition, it takes a while for the lamp to operate at its maximum (15 to 30 minutes) without mentioning flicker during startup. Do not forget the heat generated by this type of lighting. Especially that after 10000 hours of operation, they can sometimes lose 70% of their capacity. The life is also very low and the HID lamps need ballasts ... So, if they are damaged, it is even more work for their replacement. In terms of maintenance and energy costs, this is certainly not the best way. They are difficult to maintain, High bay LED vs. sodium vapor lamp and fluorescent lamps Sodium lamps are another technology used for large indoor spaces. In general, these devices have a low color temperature and poor color rendering. In addition, they require a period of startup to illu...

For what use high bay LED? What are the stakes for lighting large outdoor spaces? To be properly lit, it is important that department stores, factories or warehouses have powerful lighting to ideally cover all the space (vertical and horizontal). Most of the time, these areas have a high ceiling. This is why the luminaires used must be powerful, and the light must have a high color rendering to allow to see the products in the best way possible. In addition, employees who work there must be able to practice in secure areas. So, the solutions used for this type of application have been discharging lamps or sodium vapor lamps. However, innovations have been made with LED technology compared to traditional lighting. Here are the issues to highlight when illuminating these areas: ·          The life of the luminaires must be as long as possible ·          Use as little energy as possibl...
