Frequently Asked Questions

 What is colour temperature?
A measure of the colour of a light source at a particular temperature expressed in degrees Kelvin(K). Warm colours have a low colour temperature (approx. 2700K-3000K)and have a red-yellowish tone; these are most suitable for living rooms. Cool colours have a high colour temperature (approx. 6000K) and appear bluish; these are more clinical and therefore suitable for bathrooms, kitchens & offices. The lower the colour temperature, the warmer the colour of the light.
 What is beam angle?
The beam angle is the angle at which light is directed from the light bulb. So a small angle of 30°will focus light on a small area where targeted lighting is desired. A wide 120°beam angle will spread the light across a whole room creating softer lighting. A room with single light fitting will generally require the widest beam angle available, whereas a room with several downlights or spotlightscan use the average 30°45°60°beam angle as the light will cover different areas of the room and overlap each other.
  Which colour option should I choose?
The two key colour options you will come across in our LED bulbs are warm white and cool white. In terms of choosing, if you remember that warm white is similar to conventional lighting with a softer slightly yellow light and cool white is a brighter white light, it should help you with your decision. Generally speaking, warm white is the preferred option for living rooms and bedrooms, while cool white is more popular for bathroooms and kitchens.
  Can LED bulbs be dimmed?
They certainly can. However, in order to do so, you will need to install a low voltage dimmer switch, as standard halogen dimmer switches will not work with dimmable LED bulbs.
 Will my LED turn on instantly or does it need to warm up?
Your LED bulbs do not require time to warm up which means they turn on instantly to provide you with the high quality lighting you need. LED bulbs do not give off harmful IR or UV emissions.
 Will the light created lessen over the bulbs lifespan?
Yes it will. However, because the lifespan of the bulb is so long, the eventual dimming is practically unnoticeable and as such, much more reliable than its halogen equivalent.
 Will LED bulbs fit into my existing light fitting?
Yes. All Top-Max LED bulbs are direct replacements for your old halogens, unless otherwise stated in their description.
 Will I require an LED-compatible transformer?
You will only need anLED-compatible transformer for 12 volt bulbs(MR16, G4, and GU10). All 240volt bulbs do not require a transformer. If the minimum wattage of the transformer is greater than 20 watts, your LED will not be compatible. No-compatible transformers will cause the bulb to flicker which can damage the fixture and decrease the overall lifespan of the LED.
 What are the main features & benefits of LEDs?
The perks of an LED bulb over a halogen include a long lifespan, energy efficient consumption, low temperature, high safety levels, zero warm up time and saving money, not only on bills but also on replacement items.

 Will my existing dimmer switch work with my LED bulbs?
1) Ensure that your LED bulbs are dimmable, not all LED bulbs come with a dimmable option.
2)Your dimmer switch must be LED-compatible as standard dimmer switches will not work. Choose from one of our smooth control or touch sensitive LED dimmer switches.
 What is watt?
Wattage is the amount of power required to operate the light bulb. For example, a 60 watts of power, so if you have 5 of these halogen bulbs in a room they will consume 300 watts of power. By replacing these bulbs with LED equivalents at 7 watts each, you would be using 35 watts of power.Big energy savings without compromising on brightness!
 What is a lumen?
A lumen is the measure of the total amount of light emitted by a source. Lumens let you buy the amount of light you want, so when buying your new bulbs think lumens, not watts. Currently our LED bulbs produce approx. 80-100 Lumen per watt. Therefore as a rule, just divide your existing bulb wattage by 8-10 to get the LED replacement wattage you need.
 What is meant by voltage?
Voltage is the measurement of volts required to operate the light bulb. Generally speaking, the UK, Australia & New Zealand is 240 volts and the US & Canada is 120 volts. NB. Some bulbs work on 12 volts which require a transformer, if unsure please check our bulb selector website page.
