Frequently asked questions


Electronic ballast uses less power and runs at a PF of nearly one. A wire wound ballast is less efficient and a capacitor needs to be added to the circuit to bring the PF to be as close as possible.


The C86 comes with a four lever switch. Two switches for the heater lamps, one switch for the centre lamp and one switch for the extractor fan. If a lamp is specified for 40 watt it must not be upgraded. The reason is the lamp holder wiring and lens are designed for the wattage specified.


Many electronic devices, such as radios, televisions, wireless telephones, and remote controls, use infrared light to transmit signals. Infrequently, these types of electronic devices accidentally interpret the infrared light coming from a compact fluorescent bulb as a signal, causing the electronic device to temporarily malfunction or stop working. (For example, your television might suddenly change channels.) Fortunately, this only happens when light is produced at the same wavelength as the electronic device signals, which is rare.


To use a compact fluorescent bulb on a dimmer switch, you must buy a bulb that's specifically made to work with dimmers. Afrolux Luminance makes a dimming compact fluorescent and LED light bulbs that are specially designed for use with dimming switches. Ensure the dimmer which is offered or being used is compatible to the lamp.
{slider=CFL: Can CFLs be used in places like bathrooms?}
Yes, as long as they are not exposed to direct water.


While compact fluorescent lighting is ideal for many situations, it must be used in the right way to reap the full benefits. CFLs can take longer than an incandescent bulb to turn on and become fully lit. CFLs also need to be disposed of carefully since they contain mercury, which can be harmful to the environment.


Regular fluorescent light bulbs used in your home and office do not produce a hazardous amount of ultraviolet light (UV). Most light sources, including fluorescent bulbs, emit a small amount of UV, but the UV produced by fluorescent light bulbs is far less than the amount produced by natural daylight. (Ultraviolet light rays are the light wavelengths that can cause sunburn and skin damage.)


There are two main parts in a CFL: the gas-filled tube (also called bulb or burner) and the  electronic ballast. An electrical current from the ballast flows through the gas, causing it to emit ultraviolet light. The ultraviolet light then excites a phosphor coating on the inside of the tube. This coating emits visible light. Electronic ballasts contain a small circuit board with rectifiers, a filter capacitor and usually two switching transistors connected as a high-frequency resonant series DC to AC inverter. The resulting high frequency, around 40 kHz or higher, is applied to the lamp tube. Since the resonant converter tends to stabilize lamp current (and light produced) over a range of input voltages, standard CFLs do not respond well in dimming applications and special lamps are required for dimming service.


If the wattage is the same the lumens will be the same.


While a regular (incandescent) light bulb uses heat to produce light, a fluorescent bulb creates light using an entirely different method that is far more energy-efficient -- in fact, 4-6 times more efficient. This means that you can buy a 15-watt compact fluorescent bulb that produces the same amount of light as a 60-watt regular incandescent bulb.


One of the greatest benefits of compact fluorescent light bulbs is their energy efficiency. A CFL uses 50 to 80 percent less energy than other light bulbs. They last more than 6 times longer than incandescents and create far less heat.


This depends on the wattage and the luminaire . A rule of thumb is to replace a lamp with a CFL 5 times smaller than an incandescent. i.e. 20W CFL = 100W incandescent. One must take into consideration which CFL will fit into the existing fixture


It is the mercury that excites phosphors in a CFL, causing them to glow and give light. When electric current passes through mercury vapour, the mercury emits ultraviolet energy. When this ultraviolet energy passes through the phosphor coating, it produces light. Because mercury is consumed during lamp operation, a certain amount is necessary to produce light and achieve long lamp life.


CFL stands for "compact fluorescent lamp." As the name implies, they are compact versions of the long, tubular fluorescent lamps you know today.


Phosphor: This chemical compound lines the inside of CFL tubing. When excited, it converts ultraviolet radiation into visible light. The chemical composition of the phosphor determines the colour temperature of the light emitted by the bulb.


An electrical current from the ballast flows through the gas, causing it to emit ultraviolet light. The ultraviolet light then excites a phosphor coating on the inside of the tube. This coating emits visible light. The gases and phosphors need to warm up before they are in full operating conditions.


No cool white and warm white have the same lumen output but the Kelvin rating changes. In other words the colour is different and they have different colour temperatures on the colour spectrum. Cool white lamps run at a temperature (Kelvin of +/_ 4000K warm white at +/_ 2800. This is purely the difference in colour temperature. However for LED, there is a clear lumen difference between the two colour temperatures (The higher colour temp. Is usually higher in output than the lower ones)


Depending on the application you can replace with CFL or LED. One could also reduce the wattage of the halogen lamp from 50 to 35 watt.


Use CFL's which use less energy and last up to 10 times longer than incandescent lamps. Turn off household appliances such as microwave, TVs, Videos, music systems and computers when not in use, as they continue to use energy when they are left on standby


If one can do this and still maintain the aesthetic effect in all rooms then yes.


A light fixture is an electrical device used to create artificial light and/or illumination. A luminaire is a lighting fixture complete with the light source or lamp, the reflector for directing the light and an aperture (with or without a lens).


This can be debated. However the word bulb could mean various things from plant bulbs to light bulbs. Lamps can also be mistaken for table lamps. The common phrase in industry is LAMP.


When designed properly, an LED circuit will approach 85% efficiency, which means 85% of the electrical energy is converted to light energy.


Depending on your budget you could retrofit all lamps to LED. However if budget is a challenge one could use the smaller wattage LED's in passage areas and for accent lighting.


Rated average life for a lamp is defined as: A value of lamp life expectancy based on laboratory tests of representative lamps, burning at rated volts, on an approved system, operating with a burning cycle of 10 hours per start. The "average life" is determined when 50% of the lamps initially installed are still operating


LED Life span varies from 30000 to 50000 hours. CFL varies from 6000 to 12000 and incandescent lamps average around 2000 hours. Some Halogen lamps (with IRC technology) can also have up to 4000 hours


CFLs are safe to use in your home. No mercury is released when the bulbs are in use and they pose no danger to you or your family when used properly.


The amount of mercury in the most popular and widely used CFLs is minimal, ranging between 2.3 mg and 3.5 mg. That is lower than other CFLs on the market, which generally contain approximately 5 mg, roughly the equivalent of the tip of a ballpoint pen. The standard regulation stipulates 5 mg or lower.


If CFL breaks- carefully sweep up all the fragments, wipe the area with a wet towel, and dispose of all fragments, including the used towel, in a sealed plastic bag. If possible, open windows to allow the room to ventilate.



{slider=Stores: Where can I buy Afrolux Luminance products?}
Any one of our trusted retailers. Have a look at our online store locator for a retailer near you.


One can run at voltages of 10% higher or lower of the rated voltage indicated on the lamp. Remember 5% increase in voltage will cause a 50%reduction in life.


The warranty period is one year(for CFLs) and up to 5 years (for LEDs). It does pass onto the end user. However the faulty unit must be returned to the retailer who sold the product. Then returned to Afrolux Luminance for repairs.
