Here are a few hints and tips to help you choose lights which will save you money, rather than cost you money.
Why Work with Lighting Projects?
We know that LED lights are not suitable for all applications, and we’ll tell you when not to use them. We are not trying to ram any products in to your application.
We are interested in getting the right light for your project, whichever light that may be.
We only source high quality products from the UK. Our products usually have 2, 3 or 5 year warranties.
Wherever possible we only use products with independently verified photometric test data.
The warranty is with a UK manufacturer. Not an unknown entity hiding behind an ebay shop/website, or on the other side of the world.
We work with you, to help you select the right light for the job. We make site visits, undertake CAD simulations and can install sample lights so you can be sure you’re making the right decision.
Benefits of Using LED Lights from Lighting Projects:
- Up to 85% energy savings.
- Suitable for use with movement sensors, giving even greater savings.
- With electricity prices continuing to rise, and predicted rise, expect even greater savings.
- Typical returns on investment of 1 to 2 years.
- Reduces your carbon footprint.
- 3 and 5 year warranties, from a UK manufacturer.
- 50,000 to 70,000 hrs lamp life. Recent studies suggest that this could be as high as 130,000 hrs (15 yrs).
- When they do reach the end of their life, there is no sudden failure. They just gradually get dimmer.
- Reduced maintenance costs.
- Low heat emissions.
- No ultra violet light.
- Easy to recycle/repair at the end of their life.
Different Colours of White:
This diagram below shows approximately which colour of white light is which (for illustration purposes only).
Warm whites are more common in the home, or areas where a ‘warm’ feel is required. Neutral and Cool whites are better suited to offices and industrial applications.
Please be aware that for lamps of the same wattage, ‘warm’ lamps will emit less light than Neutral or Cool lamps. Check the lumens (lm) for each colour temperature.
What Should You Know?
Look For Lumens, Not Watts:
Two LED lamps of the same wattage may not produce the same amount of light (lumens – lm). Always check how many lumens you are getting. Lamps can vary considerably.
Some LED Lamps Are Larger Than The Lamps They Replace:
This often occurs when fitting MR16 or GU10 lamps in to downlighters and similar light fittings. Be sure to check a sample of the exact lamp before ordering your lights.
If LED Lights Get Too Hot They Will Quickly Degrade:
Some fittings, like downlights, do not allow hot air to move away from the lamp. This was not a problem with traditional lamps, but it is for LED lamps. The hotter they get, the faster the light
they produce will get dimmer, and eventually they will need replacing.
High quality LEDs with the correct drivers and cooling can last for years and years. Lamp life is declared as the number of hours before the light dims to X% or the original illumination. If it is measured at 80% then it is known as L80. Look out for lights measured at L70, and suppliers who don’t even know what their lights are measured at.
What You Should be Wary of:
A school boy can get an LED to work. It takes a lot of knowledge and experience to design a light to last for 15 years.
Cheap Lights From Ebay, Wholesalers & The Far East:
Anyone can import lights for pennies and sell them on. Ensure you are happy that the lights will perform for the hours they claim, at the correct lumens, and that they can honour the warranty.
Suppliers Which Only Quote Watts:
Remember, it is lumens which is important.
Suppliers Which Can Not Provide Photometric Data For It’s Products:
‘LM79′ and ‘LM80′ tests measure the light emitted and the rate of degradation of light from the lamp. You should request these reports – even if you don’t understand them. If they are not available it is likely that they haven’t bothered to measure or test their lights.
Suppliers Who Do Not Provide Written And Detailed Guarantees:
Check that your supplier to defines what a failure is. How many LEDs need to have failed before they will replace the unit? At what percentage of the original light level is the lamp considered to have failed? You will be amazed at what some suppliers have claimed after the sale has been made…
A warranty from a manufacturer in China can be worthless. You (or your supplier) will have to return the lights to China (at your cost) for inspection before they replace them. You then have pay for them to ship them back to the UK!
Suppliers Who Only Sell Lamps:
If you know about lighting and understand exactly what you need, then this doesn’t apply to you. If you need some help and advice in selecting the right solution for your application, then buy from someone who will do more than fulling a purchase order.
It’s unwise to pay too much, but it’s unwise to pay too little. When you pay too much you lose a little money, that is all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing you bought it to do. The common law of business balance prohibits paying a little and getting a lot. It can’t be done. If you deal with the lowest bidder, it’s well to add something for the risk you run. And if you do that, you will have enough to pay for something better.
