Quality Products, Cutting Edge Technology & Reasonable Prices
When Lumax Lighting was founded in 2009, we started off with most of the company operations automated, which allowed us to rather spend our time on technology, research and product development.
This tactic paid off – today Lumax is directed and operated by a handful of qualified staff, and we still manage to minimise our costs and deliver exceptional value to our customers. Significant growth and ongoing demand for our products has enabled us to focus on the wholesale and distribution markets.
Our product range consists of LED (Light Emitting Diode) solutions – from bulbs and downlights to flood lights, high bays, strip lights and more.
Initially, the South African market was introduced to poor-quality LED products, renowned for very poor light, inappropriate colouring or unaffordable high prices. This unfortunate state of affairs in the lighting market motivated us to source LED technology with:
- Enough power to compare well with conventional filament light bulbs
- Maximum luminous efficiency (Lumens/ Watt)
- Desirable colours and colour stability
- Reasonable prices
Our imported products are also distributed to the US and European markets, where they are being used on a large scale with huge success.
All of our products are CE and RoHS certified, and comply with South African safety requirements, as specified in IEC60598. As the local market develops and additional compliance requirements are defined, we are committed to continuously keeping our products in line with regulations.
- Environmental friendly. LED lights consumes +- 10% the power of traditional lighting.
- Solid state, thus not sensitive jarring or bumping.
- No heat build-up. LED’s produce 3,500 joule/hour, compared to 90,000 joule/hour for incandescent lamps.
- Mercury-free manufacturing.
- Not sensitive to frequent ON-OFF switching.
- Whole spectrum of colours available.
- Remote use with solar panels becomes viable with very low power consumption.
- Lucrative return on investment. Although LED’s have a higher initial cost, it has a quick payback period due to electricity saving.
- Insignificant maintenance cost, as there’s no need for frequent replacement
1st Generation: DIP (Duel In-Line Package)
DIP LED is the traditional diode/indicator-light-looking LEDs containing two connecting pins that are through-hole mounted to PCBs (Printed Circuit Boards). DIP LEDs were more widely manufactured prior to the 21st century. It has high optical decay, low CRI, and low efficacy relative to the more recent SMD LEDs. However, many DIPs are still used today in many applications.
2nd Generation: SMD (Surface Mount Device/Diode)
The SMD LED is a more recent, resilient, efficient, and long lasting technology for mass production. It allows for more efficient large quantity production and are used more often in the latest general purpose LED lighting solutions. SMDs rapidly increased in the first decade of the 21st century,and do not simply conduct current through the two small pins of the diode as with more tradition DIP technology. Some common SMDs are SMD 3528 (single chip), SMD 5050 (triple chips), and SMD 3014 (latest rectangle higher lumen output).
3rd Generation: High Power SMD
Improved higher lumen output SMDs. The SMD 3014 and SMD 2835 are examples
4th Generation: COB, MCOB and MCCOB LEDs (Multiple Chips On Board)
MCOB (Multi-Chip embedded On Board) and MCCOB (Multi- Chips and Cups On Board) is the latest and youngest (but rapidly improving) high output LED technology which integrates many small chips into one single large chip. MCOBs and MCCOBs are now widely used for many LED high bay overheads and large tunnel and flood lights.
Luminous power & efficiency
Traditionally incandescent lamps were only specified in terms of their power rating in Watt [W]. This was appropriate as a glowing filament always produces the same luminous flux per unit of power. This is however not the case for LED technology due to the presence of a driver circuit and the actual LED chips, each having its own efficiency rating. As a result it is possible to compare equivalent power rated LEDs and find that the one produces double the light of the other. It is therefore important to rather compare products in terms of the actual light they produce, expressed by the total luminous flux with the unit Lumen [Lm]. This unit describes the total light emitted from a source in all directions, i.e. not the light passing through a given surface area described by units like Lux and Candela. For both Lux and Candela one has to consider distance from a source to make comparisons.
Light Colour Temperature
Colour temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, and other fields. The temperature is conventionally stated in units of absolute temperature, kelvin [K]. Colour temperature is related to Planck’s law and to Wien’s displacement law. The diagram below is known as the CIE 1931 x,y chromaticity space. It shows the chromaticity’s of black-body light sources of various temperatures (Planckian locus), and lines of constant correlated colour temperature. In the middle where all the colours overlap, white light is achieved. Higher colour temperatures, typically 5,000 K or more, are called cool colours and appear as a bluish white. Lower colour temperatures, typically 2,700–3,000 K are called warm colours and appear yellowish white through red. Generally cool white is preferred for work environments and warm white is the better choice for typical home use to create a warm ambiance. Lumax provides white lamps in 3 different colour categories illustrated in the picture below.
The CRI (Colour Rendering Index), sometimes called colour rendition index, is a quantitative measure of the ability of a light source to reproduce the colours of various objects faithfully in comparison with an ideal or natural light source. Numerically, the highest possible CRI is 100, for a blackbody (incandescent lamps are effectively blackbodies), dropping to negative values for some light sources. LPS (Low-Pressure Sodium) lighting, for instance, has negative CRI. Fluorescent lights range from about 50 for the basic types, up to about 90 for the best tri-phosphor type. LEDs vary between 60 and 90, with 70 considered reasonable, and above 80 is good. The picture on the left compares an ideal CRI with that of a fluorescent. It is clear that some colours are lost, when a low CRI light source is used.
The rated, or expected, life of an LED ranges between 35,000 and 50,000 hours. This is an estimated 30 times more than the most common incandescent bulbs and more than 10 times that of fluorescent lights.
Warrantees vary from 1 to 3 years depending on the product category.
