Q1. How much energy can you save?
Traditional fluorescent tubes and incandescent light bulbs (most of them are now banned in the EU), were very wasteful. On average, 60 Watts of electrical power was consumed and most of which was wasted as heat. MLI LED light bulbs use up to 90% less power ( 5 or 6 Watts) for the same light output.
A LED bulb that has been running for several hours is still cool enough to hold in your hand !
Q2. How can MLI save you money?
MLI LED products provide outstanding value for money. Our LEDs have a projected operating life of up to 50,000 hours whereas an incandescent will only last for approximatley 1,000 hours. Therefore, you do not only you save on your lighting electricity bill, but you save on maintenance, trips to the shops and that valauable space in that drawer full of replacement lamps which never seems to include the one you need. So with the extra savings on energy, plus a much longer product life, an average user will usually recoup the initial cost very quickly. After that, with normal usage the average user will be saving up to 90% of the energy costs of the lighting installation. So if you replaced all the traditional fluorescent tubes and light bulbs with LEDs, you could eventually save hundreds, if not thousands of dollars over the lifetime.
Q3. Do they take a long time to warm up?
MLI LED tubes and lamps reach full brightness in just a fraction of a second, a comparable time to fluorescent tubes and incandescent bulbs, and are brighter for the power consumed. There is no light delay especially important in “quick in and out” domestic situations, such as kitchen, bathrooms etc.
Q4. Are low energy types as bright as ordinary light bulbs?
Remember, the wattage of a traditional fluorescent tube or a traditional light bulb told you how much power it used, not how much light it produced (most went up in heat). So to compare light output realistically we need to measure the actual light output in Lumens. If we do that, and take the actual power consumption of the tube or light bulb into account, we can say that for the same energy consumed, low energy LED tubes or lamps produce far more light output than fluorescent and incandescent types.
As a rule of thumb, to replace a T8 36W fluorescent tube would require a 12 Watt LED tube and a 60 Watt incandescent bulb would require an 7 Watt LED bulb.
Q5. Do low energy bulbs contain harmful substances?
All low energy lamps – just the same as incandescent bulbs - contain minute traces of chemicals, which in large quantities would be toxic. LEDs function correctly by using chemical compounds which emit light when stimulated by an electric current, but the products are extremely safe, and indeed LEDs are used across a wide range of consumer products like TVs, mobile phones, torches and cameras. Older, low quality CFLs from other manufacturers could contain liquid mercury while LEDs are mercury free. So LEDs are entirely safe to use.
Q6. Can LED tube cause headaches?
Migraine sufferers who are particularly sensitive to light triggers usually have problems with intense or flickering light sources, or even variations in colour temperature. When the original fluorescent lamps (straight fluorescent tubes) were first introduced, they operated at mains frequency, which caused severe problems for people who were especially sensitive to flickering light. While some highly sensitive sufferers are still vulnerable to even the smallest trigger, much of this problem has now been resolved. We are not aware of any medical light sensitivity issues with our LED based lighting products.
Q7. Are low energy bulbs dangerous?
Despite a great deal of rather sensationalised media comment based on inaccurate data, the fact is that in confined domestic spaces, MLI LED lighting products are actually much safer to use than traditional fluorescent and incandescent types. Firstly, they generate very little heat, and so are much safer where children are concerned, and present a lower risk of burning lamp shades or fabric. Secondly, in the case of both LEDs, the glass globe is protected with a plastic skin, making the glass in MLI lighting products far more difficult to break than an ordinary one.
Q8. Do I have a warranty on my lamps?
All our ranges of offer a warranty.
1. All lamps produced are guaranteed for three years.
2. The warranty covers those marketed by MLI, provided that the failure occurs by the same manufacturing defect attributable
to MLI.
3. This warranty does not cover whose improper handling, installation, or any other reason that affects the normal performance
or operation of the equipment sold.
4. The warranty period starts from the date of delivery and acceptance by the customer.
5. There is a possibility of extending the warranty (this clause is subject to additional conditions, and availability).
Q9. Do LEDs work with dimmer switches?
Most of MLI LED products are dimmable and may work with dimmer switch recommended by us, especially for areas where require smooth, controllable dimming.
Q10. What is important of a good LED lighting?
LED lighting is not just a question of the LED light sources.
A lot of other factors have to be considered:
- Optimal thermal conditions are essential to achieve long life and utilise LED light sources as efficiently as possible.
- LED light source and driver have to match in order to obtain the highest light output.
- Colour rendering has to be a least Ra>80 to obtain the best reproduction of natural light.
- The degree of colour variance (MacAdam’s factor) between each LED has to be as low as possible (>3SDCM) for the most
uniform colour experience
- A high lm/W gives a more energy efficient lighting solution and is a better efficiency indicator than light output ratio (LOR)
- The optical solution must be adapted to the LED light source for the highest possible efficiency and glare control
