Which is More Energy Efficient, LED or Fluorescent?

Energy prices have been rising gradually over the past decade. Essentially, the cost of fuel and electricity has increased to unprecedented levels, leading to higher utility bills for property owners and renters

Fortunately, you can cut down on your bills using several methods. For most homeowners, the first step would be to replace the HVAC system with a more energy-efficient air conditioner. This might work for a while, but it is not enough. Your best bet in regards to lowering electricity costs is installing energy-saving lighting systems.

When it comes to energy-efficient light installations, two types of bulbs come to mind. These include LED and Fluorescent Lights.

LED Lights

Light Emitting Diodes (LEDs) are extremely energy efficient bulbs that produce light when a current passes through them. Essentially, they consist of semiconductors that convert electricity into light.

Previously, LEDs were only a preserve for traffic lights, penlights and instrument panels. However, this is no longer the case. They are now common in most buildings due to their efficiency.

According to ENERGY STAR, LEDs use only 20% – 25% of energy compared to traditional bulbs. Essentially, they require only 2 to 17 watts of electricity, which is about 1/30 of what fluorescent lights use.

In addition, LEDs last ten times longer than fluorescent lights, and 25 times longer than incandescent bulbs. The fact that they do not have a filament means that they are more durable than any other type of bulb in the market.

Another highlight is that LED lights emit very little heat, as a result, conserving more energy. Moreover, you can use this option with solar panels, subsequently saving more money on lighting costs.

Fluorescent Lights

Fluorescent lights (CFL) are similarly energy-efficient bulbs. However, they work in a different way to LED lights in that current has to flow between the electrodes inside the bulb for it to light. This may take up to 3 minutes for the bulb to light fully. Moreover, fluorescents produce heat and use about 80% of this energy to generate light.

What is more alarming is that fluorescents give off UV/IR radiation. This could be dangerous in the long-term, given that it is one of the leading causes of eye fatigue and eyestrain.

In terms of energy usage, fluorescent lights require 10 to 20 watts of electricity. This is significantly higher than LEDs. Nevertheless, fluorescent lights use 50% to 80% less energy compared to incandescent bulbs.

So which one is more energy efficient?

Based on these facts, LED lights seem to be more energy-efficient than fluorescent lights. In essence, LEDs require less electricity and last longer than all other types of bulbs. This guarantees more savings in terms of lower electricity bills. Even though LEDs might be more expensive initially than fluorescent lights, they make up for this shortcoming by offering more in energy savings.

Enlist a professional technician

Lighting contributes to about 5% to 10% of all energy costs. However, you can reduce these costs significantly by installing the right light fittings in your home. This calls for the services of a professional electrician. We, at Quick Spark, are experienced electricians and can help you with installing the right lighting system in your home.
