Frequently Asked Questions

Low energy

Is low energy the same as low voltage?

No - it can get a bit complicated, but the long and short of it is that it's the watts that count not the volts.

We've written an article to explain the difference between low voltage and low energy.

How do I compare the brightness of low energy bulbs to normal bulbs?

A low energy bulb has a much lower wattage because it uses less electricity. In general the light output from a low energy bulb is equivalent to a wattage 4-5 times higher in an incandescent bulb. This is effected by the size and shape of the low energy bulb.

e.g. A 9w low energy bulb will generate approximately as much light as a 40w standard bulb. A 15w low energy bulb is roughly equivalent to a 75w normal bulb.

The correct way to compare light bulb brightness is to check how many lumens each light bulb produces. Lumens is a measure of light output, so the higher the number the more light the bulb produces.

This is further complicated by the spread of light from each light bulb. A small amount of light spread over a small area can appear very bright and intense, when compared to the same amount of light (measured in lumens) spread over a wide area. This only really affects spot light bulbs, that produce a beam of light, instead of sending light out in all directions. Some light bulbs produce a very narrow beam of light, and others are much wider.

How much energy do I save by using Low Energy Light bulbs?

In general, a fluorescent low energy light bulb, like the ones used in many our products, use about 80% less electricity than a standard incandescent light bulb.

Recently LED light bulbs are becoming popular for good reason. Many LED light bulbs are now suitable general lighting and can use 90% less power than an incandescent light bulb.

Do low energy light bulbs takes ages to 'warm up'?

No, although fluorescent light bulbs do take a few seconds to reach full brightness, most modern bulbs take no more than about 40 seconds to reach nearly their full output. Additionally modern fluorescents usually start instantly at a reasonable level and increase their output very quickly.

If this warming up timer is problem for you, then you should use LED light bulbs, as these start instantly at 100% of their full output, there's no warming up at all.

Can I use dimmer switches with low energy lights?

Not usually. Not many of our low energy products are suitable for use with dimmer switches. This technology is developing quickly and manufacturers are launching various dimmable products on a regular basis.

Currently dimmable low energy light bulbs do exist, but they are considerably more expensive then their non-dimmable counter parts. Most manufacturers recommend using at least 2 or 3 low energy dimmable bulbs per dimmer switch, as most dimmer switches have minimum load requirements for correct operation.

Some manufacturers publish data about which dimmer switches are compatible with their products.

How long do low energy bulbs last?

The low energy fluorescent bulbs that we sell generally have an average rated life of 8000 hours, which should be years of normal use.

LED bulbs should last much longer - most have an average rated life of at least 20,000 hours. Some are rated as high as 50,000 hours. As with fluroescent

We (or in some cases the manufacturer directly) will replace any fluorescent or LED light bulb purchased from us, within 12 months in the event of its failure as long as you have used it in accordance with the manufacturers recommendations. We will usually require you to return the faulty product to us before we can issue a replacement.

In addition to this, some manufacturers (notably tp24) will guarantee their LED products for two years. You are often required to register your new product with the manufacturer to extend the guarantee beyond 12 months. After the initial 12 months, the manufacturer should be contacted directly regarding the failed product.

Product installation

Does My Green Lighting install the products?

No. My Green Lighting only supplies the lighting products. You are responsible for the installation.

We recommend that you employ a qualified electrician for all electrical work.

Can you recommend an installer in my area?

At the moment we're not able to recommend particular electricians in any area.

Can I install low energy products in a bathroom?

Some of our products are suitable for use in bathrooms. Bathrooms are divided into different 'zones' for the purpose of electrical fittings. See our page of ip44 information for more details.

The products are marked with a water symbol on this website if they have an IP rating which makes them suitable for use in a bathroom.

If you are in any doubt about the installation of your products, you should consult a qualified electrician.

MGL Points

What are MGL Points?

It was a customer loyalty scheme whereby customers could earn a discount on future orders.

It was discontinued in 2019 because the standard prices at My Green Lighting had been reduced to a very competitive level and quantity discounts had been introduced for many products.
