How to choose the right light bulbs for your home

June 27, 2022 by No Comments

Although it may seem easy to buy light bulbs, there are many things to consider when choosing the right bulb. Pendant lights, chandeliers and other fixtures that light up your home all use different types and voltages of light bulbs. If you want to create a certain atmosphere in your home or office, you will need to select the most efficient bulb.

Here are the more complex parameters of lighting. Unless you are, you may not be an expert on lighting factors like temperature, illuminance, and colour rendering index. These are important indicators that must be considered. It can be difficult to choose the right bulb for your lighting fixtures, given the variety of available light bulbs and the technicalities involved. We have created a comprehensive guide to help you make the right choice.

The Primary Characteristics for a Light Bulb

These are the essential factors to consider before heading to your local hardware store or home depot to buy your light bulbs. Ensure you get everyone for the best fit, function, and energy consumption.

Base Type or Cap

The metal cap, or base, of a lightbulb, is the part that connects it to the socket. It provides electrical contact and secures the bulb in the fitting. Two bulbs are most commonly used in home lighting fixtures: pin or peg bases and screw bases.

  • Screw: Also known as the Edison base, this base is made of threaded metal and holds the bulb in a socket. Screw-based bulbs are very common in homes and are mainly used for decorative lightings like lamps and chandeliers.
  • Pins and Pegs: These bases have two metal stumps or rods at the bulb’s base. They can be pushed or snapped to the socket instead of being screwed. These are used in small incandescent lightbulbs and some types of fluorescent lamps.

When buying bulbs for lighting fixtures, it is important to identify the right cap or base type. You can take out any bulb already in your fixture to verify the size and type. To purchase a new bulb, bring the old one to your local hardware store or home depot. If the fixture is not yet installed, you can use the fitting reference number to locate a suitable bulb.

They are coded to determine the type of light bulb or their fitting. The base name is indicated by the letters, while the number indicates the diameter in millimetres. An E27 bulb, for example, is an Edison screw-type bulb with a diameter of 27 millimetres. The E14 bulb, on the contrary, is a similar base, but it will fit into a smaller socket.

Voltage

The pressure at which electricity flows into an electronic device is called voltage. It is measured in units called volts. The 120-volt standard voltage supply for US homes is required by most indoor lighting. This is why 110-120 volt bulbs are recommended. Low voltage lighting is required for outdoor fixtures. These can be used with 12- or 24-volt bulbs. Safety is the main reason low voltage lighting is preferred for outdoor use. Because outdoor lighting is more likely to be exposed to the elements, electric shock risk is greatly reduced.

Wattage

Wattage is the energy required by a lightbulb and is measured in watts. It was used to determine brightness when there were limited options for bulbs other than halogen and incandescent. However, wattage is no longer an indicator of how bright a bulb will be. LED bulbs, for example, have a lower wattage but provide a significantly brighter light output.

Nowadays, brightness is measured using units of luminous flux (LMS). Lumens are the light that a bulb emits, regardless of its use. A bulb that produces more light will have a higher lumen count. This is a better indicator of brightness. You can find light bulbs that have higher lumen values at lower power. This means that you get better lighting for a lower cost.

To get the best light output or lumens per Watt, we recommend LED bulbs. LEDs produce 70-90 lumens/Watt, while incandescent bulbs only produce 10 lumens/watt. A 5w LED lamp can be equivalent to a 35-45 watt incandescent.

Other Parameters to Consider when Choosing Light Bulbs

It is more than choosing the right base type, voltage, and wattage for your bulbs. You can improve the functionality and appearance of your living area by considering other factors. Let’s look at three lighting options that can provide more comfort and convenience, particularly if you are trying to create a certain ambience.

Illuminance

Illuminance refers to the amount of light that radiates from a source of light and spreads over a surface. This can determine the brightness level you want in various areas of your house.

Illuminance can be measured in Lux (lx) but not with lumens. Illuminance is the amount of light that hits a surface, while Lux is the amount of light that falls on it (illuminance). Lumens measure the light a bulb emits in all directions (luminous flow).

It’s not difficult to find the right light bulb for you. One Lux equals one lumen per square meter. To determine the brightness level, you will need to measure the area you wish to light up.

Experts recommend 300 to 400 lumens per square meter light levels in an office, study or other space. A 10-square-meter home office will require approximately 3,000 to 4,000 lumens for the best illumination.

Colour Temperature

The colour temperature is the degree of warmth or cold a light source provides. It is measured in Kelvins (K), and the higher the Kelvin, the whiter or cooler light. People prefer a warmer light source with a lower Kelvin rating for low-illuminance areas like the bedroom, living room, and dining area. A cooler light source with a higher Kelvin rating would be recommended for areas that require high levels of illumination, such as the study, kitchen, and bath area.

Below is a chart and list of colour temperature classifications for residential applications.

  • Soft (1,000 to 2,700 Kelvin).
  • Warm (2,700 to 3,000 Kelvin): A warm yet comfortable atmosphere.
  • Bright White (3,000 to 4,500 Kelvin). A mixture of blue and white tones creates a lively, energetic feeling.
  • Daylight (4,500 to 6,500 Kevin): This colour is more bluish and has the highest contrast.
