Hey there, if you’ve ever stared up at a string of twinkling ornaments lights during the holidays, or when you’re sprucing up your backyard for a summer party, and thought, “How much juice is this thing actually using?” — you’re not alone. I get asked this question all the time as an ornaments light supplier. Folks want to know if these little bulbs are going to hike up their energy bills, if they’re eco-friendly, or even if they’re worth splurging on vs. those cheap knockoffs from the grocery store. Let’s break this down, no fancy jargon, just real talk about what energy rating for ornaments lights actually means. Ornaments Light
First off, let’s get one thing straight: energy rating isn’t a random number they stick on a box to confuse you. It’s basically a way to measure how much power a light uses (in watts, duh) and how efficiently it turns that power into light (not wasted heat). For ornaments lights, this rating is super important because unlike your big living room TV that runs once a day, ornaments lights often run for hours — sometimes all night, for weeks at a time. I’ve had customers tell me they leave their outdoor tree lights on 24/7 for the whole holiday season, and they’re shocked when their electric bill comes in. That’s where knowing the energy rating comes in handy.
Let’s start with the two main types of ornaments lights you’ll find out there: incandescent and LED. If you’re old school, you might remember the big, blobby incandescent bulbs that get so hot you could burn your hand touching them. Those are basically tiny little heaters that happen to make light. LEDs? They’re the cool (literally) kids on the block, and their energy ratings are night and day. Let’s do a quick example: a standard incandescent C9 ornament bulb uses about 15 watts each. A LED C9 bulb that puts out the same bright light uses only 1.5 watts. That’s 10x less power! I see customers all the time who go from incandescents to LEDs and think their electric meter is broken. Spoiler: it’s not — it’s just using way less energy.
Now, what’s the actual energy rating label for ornaments lights? In most countries (US, EU, Canada, etc.), you’ll see two main things: the wattage per bulb (or per string) and sometimes a star rating or efficiency class. In the US, the Federal Trade Commission (FTC) requires light bulb manufacturers to list the wattage, lumens (that’s how bright the light is, not watts — important!), and energy use. For strings of ornaments lights, they’ll usually give a total wattage for the entire string. Like, a 100-bulb incandescent string might be 40 watts total, while a 100-bulb LED string is 5 watts total. That’s a huge difference.
Wait, but why does wattage matter more for ornaments lights than other things? Because most people don’t use one string — they use multiple. I had a customer last year who put up 20 incandescent strings around his house for Christmas. Each string was 40 watts, so 20 x 40 = 800 watts. If he ran those for 8 hours a day for 30 days, that’s 800 watts x 8 hours x 30 days = 192,000 watt-hours, which is 192 kilowatt-hours. At the average US electricity rate of $0.15 per kWh, that’s $28.80 just for the lights. For LEDs? 5 watts per string x 20 strings = 100 watts total. Same usage: 100 x 8 x 30 = 24,000 watt-hours = 24 kWh, which is $3.60. That’s a massive difference, and that’s all because of the energy rating.
A lot of people ask me, “Are all LED ornaments lights energy efficient?” The short answer is yes, but not all are created equal. Some cheap LEDs you can find online or at the dollar store have really low-quality diodes, which means they might not be as efficient as they claim. I’ve tested a bunch of those — some “LED” strings that say they use 5 watts for 100 bulbs, but actually use closer to 7. That’s a red flag. The real way to check is to look for a third-party certification. In the US, that’s Energy Star. If a string has the Energy Star label, you know it’s been tested to meet strict efficiency guidelines. I only carry Energy Star certified ornaments lights because I don’t want my customers getting ripped off. In the EU, it’s the CE marking and energy efficiency classes A to G, with A being the most efficient.
Another thing I get asked: “What about solar ornaments lights?” Are those even worth the energy rating?” Solar lights are a whole different ballgame, but their energy rating still matters. A lot of people think solar lights run on “free energy” so they don’t have to worry, but that’s not exactly true. The solar panel charges a battery during the day, and the light uses that stored energy at night. The energy rating here is usually based on how much power the LED uses, and how long the battery lasts. A good solar ornaments light will have an LED with a low wattage (like 0.5 watts per bulb) and a battery that can last 8-12 hours on a full charge. The cheap solar ones might use a slightly higher watt bulb, so the battery dies after 4 hours. I always tell customers to look for solar lights with high-efficiency LEDs — that’s where the real savings are, even if you don’t see a monthly electric bill.
Let’s talk about common misconceptions. A lot of folks think “lower wattage means dimmer light,” but that’s not true at all. That’s why lumens matter more than watts for brightness. A 100-lumen LED is just as bright as a 100-lumen incandescent, but the LED uses way less watts. So when you’re looking at energy ratings, don’t just look at the watt — check the lumens to make sure you’re getting the brightness you want. I see this all the time: someone buys a super cheap LED string that says “2 watts” but only puts out 50 lumens, and they’re disappointed because it’s too dim. Then they go back to incandescents, which use way more watts but are brighter. But with a little research, you can find LED ornaments lights that are bright and energy efficient.
Another big one: “Do ornaments lights use more energy if they’re on a dimmer?” That’s a question I get all the time, especially for people who like soft, twinkling lights for their bedroom or patio. The short answer is no — as long as they’re LED. Incandescent dimmers actually work by reducing the voltage, which wastes more energy as heat, so they might use a tiny bit less, but not much. LED dimmers are different — they adjust the current, so you get the same efficiency even when they’re dimmed. I carry dimmable LED ornaments lights, and my customers love them because they can set the mood without jacking up their energy bill.
Now, let’s get into the real-world numbers, because that’s what matters. Let’s say you have a standard 10-bulb string of ornaments lights. If it’s incandescent, that’s 150 watts total. If you run it for 5 hours a day, 30 days a month, that’s 150 x 5 x 30 = 22,500 watt-hours = 22.5 kWh. At $0.15 per kWh, that’s $3.38 per string per month. For LED, same 10-bulb string: 15 watts total. Same usage: 15 x 5 x 30 = 2,250 watt-hours = 2.25 kWh, which is $0.34 per string per month. That’s a 90% savings, folks. Multiply that by 10 strings, and that’s $30.40 vs. $3.40 per month. That’s the kind of difference that adds up over time.
I also want to touch on eco-friendliness, because a lot of customers ask about that too. Energy rating is directly tied to how much carbon emissions you’re putting out. If your ornaments lights use less energy, that means less power is coming from power plants (even if it’s from renewables, it’s still better to use less). Incandescent ornaments lights have been banned in some countries because of their low efficiency, and that’s not by accident. They’re basically a waste of energy. LED ornaments lights last way longer too — like 25,000 hours vs. 1,000 hours for incandescents. So you’re not only saving on energy bills, you’re not throwing out bulbs every year, which is better for the planet.
Wait, but what about if you’re using ornaments lights for a one-time event, like a wedding or a party? Should you even care about the energy rating? Yeah, actually. Even if it’s just one weekend, if you’re running 20 strings for 10 hours a day, that adds up. And if you’re renting those lights, the rental company should be using efficient ones for you anyway. I’ve had event planners come to me asking for the most energy-efficient lights because their clients don’t want to pay a huge electric bill for a weekend event. It’s a thing now, and it’s going to become even more common as energy costs keep going up.
Let me also bust a myth about extension cords and energy use. A lot of people think if you plug a bunch of ornament light strings into a long extension cord, that uses more energy. No, that’s not how it works. Extension cords have a tiny amount of resistance, but for the short lengths most people use for ornaments lights, it’s negligible. The energy use is all in the bulbs themselves, so that’s what you need to focus on. Just make sure you use outdoor-rated extension cords if you’re putting lights outside — that’s a safety thing, not an energy thing.
Now, as someone who’s been in the ornaments light supplier game for years, I can tell you that the biggest mistake people make is just grabbing whatever string looks pretty at the store, without checking the energy rating. I’ve had customers come back to me saying they switched to my LED lights and their electric bill dropped by $50 a month during the holiday season. That’s a huge win, right? Especially with how much people are paying for energy these days.
So, what should you actually look for when buying ornaments lights, energy rating-wise? First, check if they’re LED — not all LEDs are equal, but they’re way more efficient than incandescents. Second, look for Energy Star (US) or CE A/B ratings (EU) to make sure they’re actually efficient, not just labeled as such. Third, don’t just look at wattage — check lumens to make sure you’re getting the brightness you want. Fourth, if you’re using them for long periods (like holiday lights), calculate the total wattage of all your strings and do a quick math check on your electric rate to see what you’ll be spending.
At the end of the day, the energy rating of ornaments lights is just a way to tell you how much they’ll cost you to run, and how eco-friendly they are. It’s not rocket science, but it’s important to pay attention to, especially since we use these lights so much. I always tell my customers: invest in good, energy-efficient ornaments lights now, and you’ll save money on your electric bills for years. Plus, you won’t have to replace bulbs every year, which is a hassle.
