How Often Should I Replace My Lights at Home?
Nothing is more frustrating than a lightbulb flickering out when you turn it on – many people aren’t prepared for it and don’t have spares on hand.
The truth is if we can recognize the indications of a fading light bulb and have extras on hand, we will never be without light again.
When Should You Change Your Lightbulbs at Home?
If the light is dimming, it’s a definite indicator that it’s time to visit a lighting shop. Replace the bulb as soon as it dims and make sure you have spares on hand. Moreover, keep an eye out for bulbs burning brighter than usual. This might indicate burnout.
Flickering or humming noises might be a warning that a light bulb is ready to burn out, or they could signal a more significant problem like a loose wire. If you’re not sure, ask a professional to check it out.
A decrease in the length of time it takes for a light bulb to light up is another sign that it needs to be replaced.
Different Types of Lights and When to Replace Them
The life duration of different types of light bulbs varies, including decorative lights. This section goes through the most common choices and how long they are expected to last.
1. Incandescent Light Bulbs
Incandescent light bulbs are becoming rare as the shift to greener energy continues. Yet, people continue to use them since they are typically less expensive to purchase.
It’s estimated that incandescent lighting will last between 750 and 1000 hours. However, some sources claim that this type of light can last up to 2000 hours of use. If your incandescent light bulbs are within this range, you should consider a replacement.
2. LED Light Bulbs
LED light bulbs are more costly, but they last considerably longer and save money over time. Most lighting manufacturers claim that an LED light bulb will last between 25,000 and 50,000 hours, eliminating the need to replace them as frequently; these bulbs can even last four years.
3. Low Energy Light Bulbs
Low energy light bulbs may last up to 10 years depending on the brand and wattage, and many people prefer them since they are more environmentally friendly. Consider replacing your low energy light bulbs if you have used them for up to ten years.
4. Grow Lights
Many indoor gardeners know that their grow lights depreciate or emit less light with time, reducing crop yields and lengthening growth cycles. However, learning when to replace your lights takes some planning, whether you’re a novice or a seasoned grower.
Whether you’re using a metal halide (MH), high-pressure sodium (HPS), or T5 fluorescent grow lamp, your lights will ultimately dim due to external heat, the huge starting voltage from the ballast, or simply normal wear and tear.
After 20,000 hours, an MH bulb will depreciate approximately twice as much as an HPS bulb due to its unique design and components. In general, an MH bulb will lose 50% of its brightness in 6 to 10 months, depending on the number of hours per day it is used.
An HPS bulb will last longer, lasting 10 to 14 months before needing to be replaced. Because light depreciation is so gradual in T5 fluorescents, they will last the longest. For 18 to 24 months, you won’t need to change the bulb.
Fluorescent bulbs last around two years on average. Unfortunately, their efficacy begins to deteriorate beyond this period. As a result, if you use them year-round, you need to replace them every two years.
In a Nutshell
Light bulbs can’t burn indefinitely, and incandescent bulbs have a lifetime of about 900 hours. Therefore, a bulb should last around four months based on an eight-hour-per-day use pattern.
CFLs are intended to last a long time. However, this isn’t always the case. If you’ve recently replaced bulbs and they don’t last as long as they should, the problem might be with the fixture or with the circuit as a whole.
