Hey there, let\u2019s cut to the chase\u2014if you\u2019ve been walking past your old incandescent or even CFL bulbs and thinking, \u201cThese cost way too much to run,\u201d you\u2019re not wrong. As someone who\u2019s been an LED round bulb supplier for the last 7 years, I get asked this question all the time<\/em>: \u201cHow much actual cash do I save by swapping my old bulbs for LEDs?\u201d It\u2019s not just a vague \u201cthey\u2019re cheaper to run\u201d answer\u2014there\u2019s hard math, real-world use cases, and even little tricks I\u2019ve seen customers use to stretch those savings even further. Let\u2019s break this down like I\u2019m chatting over a coffee, no confusing jargon, and no fake numbers made up just to sound flash. LED Round Bulb<\/a><\/p>\n

<\/p>\n

First, let\u2019s set the baseline because everyone\u2019s situation is different. I\u2019m gonna use the most common scenarios I see: a regular household (3 people, 10 bulbs total: 8 living areas\/bedrooms, 2 bathrooms), a small caf\u00e9 (12 bulbs, all on 12 hours a day, plus a display case that runs extra), and a small office (15 bulbs, mostly 9am-5pm, 5 days a week). Why those? Because those are the folks hitting up my inbox every week asking for bulk quotes.<\/p>\n

Let\u2019s start with bulb basics, no textbook stuff. Old incandecent bulbs\u2014you know, the ones that get hot enough<\/em> to warm a small room instead of lighting it\u2014usually run at 60 watts each. Yeah, that\u2019s the super inefficient ones. CFLs, the curly ones everyone switched to for a hot minute, are better but still not great at 14 watts. My LED round bulbs? We make a standard 9-watt LED round bulb that puts out the exact same light<\/em> as that 60W incandecent. No \u201cdim\u201d or \u201charsh\u201d light\u2014same brightness, way less power. That\u2019s the key number here: 9W LED vs 60W incandecent, 14W CFL. Got it? Good.<\/p>\n

Now, let\u2019s talk electricity costs because this isn\u2019t a US-only thing\u2014wait, no, I\u2019ll use average US numbers first since that\u2019s where most of my retail\/ small business customers are, but I\u2019ll note it translates to almost every country. The average US residential electricity rate right now is ~16 cents per kilowatt-hour (kWh). Small businesses are a bit lower, around 12 cents, because commercial rates are bulk. Let\u2019s do the math per bulb<\/em> first, then scale it up.<\/p>\n

Per bulb, per hour: 1 kWh = 1000 watts. So a 60W incandecent is 0.06 kWh per hour. At 16 cents\/kWh, that\u2019s 0.96 cents per hour. The 9W LED is 0.009 kWh per hour, so 0.144 cents per hour. Wait, that\u2019s wild\u2014almost 7 times cheaper per hour<\/em> for the same light. Let\u2019s check CFL too: 14W is 0.014 kWh, 0.224 cents per hour. Yeah, LEDs still smoke them.<\/p>\n

Now, let\u2019s factor in how long bulbs last because that\u2019s the other big cost people forget. Incandecents die in ~1,000 hours\u2014like, you buy a pack of 4, use them a few months, gone. CFLs are better, ~8,000 hours. Our LEDs? We test them at 25,000 hours minimum. That\u2019s 25 times longer than an incandecent, 3 times longer than a CFL. So you\u2019re not just saving on electricity\u2014you\u2019re buying way fewer bulbs, which adds up. Let\u2019s say a pack of 4 incandecents is $2, so $0.50 per bulb. CFLs are $1 each, our LEDs are $3.50 each. That\u2019s a higher upfront cost, but wait\u2014spreading that over their lifespan: incandecent costs $0.50 \/ 1,000 hours = $0.0005 per hour. LED is $3.50 \/ 25,000 hours = $0.00014 per hour. Oh, right\u2014so even the bulb itself<\/em> is cheaper per hour, not just the electricity.<\/p>\n

Let\u2019s do a real household example first because that\u2019s the one I get most. 10 bulbs in a home, each used 3 hours a day on average. Let\u2019s compare full year (365 days):<\/p>\n

Old incandecent setup: 10 bulbs x 60W = 600W total, used 3h\/day = 1,971,000 Wh (1,971 kWh) per year. At 16 cents\/kWh, that\u2019s $315.36 just for electricity<\/em>. Plus bulb replacements: 10 bulbs \/ 1,000 hours lifespan = 3.65 bulbs per year (since 3h\/day x 365 = 1,095 hours per bulb, so ~1.1 replacements per bulb yearly). 3.65 bulbs x $0.50 = $1.825. Total annual cost for incandecents: ~$317.19.<\/p>\n

LED setup: 10 bulbs x 9W = 90W total, 3h\/day = 295.65 kWh per year. 295.65 x $0.16 = $47.30. Bulb replacements: 10 bulbs \/ 25,000 hours = ~0.044 bulbs per year (they\u2019ll last 6+ years in this home). So bulbs cost you basically nothing\u2014round to $0. Total annual cost: ~$47.30. Wait, that\u2019s a savings of $269.89 per year<\/em> for a 10-bulb home. That\u2019s enough to cover a month of groceries, or a new pair of nice shoes, or a whole month of streaming services\u2014no cap.<\/p>\n

What about a small caf\u00e9? They\u2019re my second most common customer\u2014our caf\u00e9 accounts usually swap 12 bulbs, all on 12 hours a day, 365 days a year. Commercial electricity rate is 12 cents\/kWh, so let\u2019s run that:<\/p>\n

Old incandecent caf\u00e9: 12 x 60W = 720W, 12h\/day = 3,153.6 kWh\/year. 3,153.6 x $0.12 = $378.43. Bulbs: 12 bulbs, each used 12h\/day = 4,380 hours\/year, so incandecents last ~0.228 years each, so ~4.39 bulbs\/year. 4.39 x $0.50 = $2.20. Total: ~$380.63\/year.<\/p>\n

LED caf\u00e9 setup: 12 x 9W = 108W, 12h\/day = 473.04 kWh\/year. 473.04 x $0.12 = $56.76. Bulbs: 12 bulbs, lifespan 25,000 hours = ~5.7 years, so 0.175 bulbs\/year, basically free. Total: ~$56.76. Savings here is $323.87 per year<\/em>\u2014that\u2019s enough for a new coffee machine, or a month of rent for a small storage unit, or way more bulk coffee beans. I had a caf\u00e9 owner in Portland last year who swapped all his bulbs and used the savings to add a vegan pastry case\u2014said that LED swap paid for itself in 3 months. Wild, right?<\/p>\n

Wait, let\u2019s not forget the small office\u2014most small 10-person offices have 15 bulbs, on 9am-5pm (8 hours), 5 days a week, so ~2,080 hours a year. Commercial rate is 12 cents here too.<\/p>\n

Old incandecent office: 15 x 60W = 900W, 2,080h\/year = 1,872 kWh. 1,872 x $0.12 = $224.64. Bulbs: 15 bulbs, each used 2,080h, incandecent lifespan 1,000h = ~2.08 replacements, so 15 x 2.08 = 31.2 bulbs\/year x $0.50 = $15.60. Total: ~$240.24.<\/p>\n

LED office setup: 15 x 9W = 135W, 2,080h = 280.8 kWh. 280.8 x $0.12 = $33.70. Bulbs: 15 bulbs last 25,000h = ~12 years, so negligible cost. Total: ~$33.70. Savings here is $206.54 per year<\/em>\u2014that\u2019s enough for a new printer, or a team lunch, or supplies for the office break room.<\/p>\n

But wait, I know what you\u2019re thinking: \u201cWhat if I live in a place with higher electricity rates?\u201d Like Hawaii, where residential rates are ~37 cents\/kWh? Let\u2019s recalculate that household example. 10 bulbs, 3h\/day, 37 cents\/kWh. Incandecent electricity cost: 1,971 kWh x $0.37 = $729.27. LED electricity cost: 295.65 x $0.37 = $109.39. Savings jumps to over $619 per year<\/em>! That\u2019s like a plane ticket to a nearby state, or a new laptop, no joke.<\/p>\n

Also, let\u2019s bust a common myth I hear all the time: \u201cLEDs are too dim.\u201d Our round bulbs are rated for lumen output\u2014we sell 800-lumen (same as 60W incandecent), 1000-lumen, even 1200-lumen for brighter spaces like garages or workshops. So you can pick the exact brightness you need, no compromise. And unlike some LEDs, ours don\u2019t have that weird blue tint that makes your kitchen look washed out\u2014they\u2019re warm white (2700K) like old incandecents, so your home feels cozy, not like a hospital.<\/p>\n

Another tiny hidden savings: heat. Old incandecents give off 90% of their energy as heat, right? So in the summer, your AC has to work harder to cool down that extra heat from bulbs. Last year, a customer in Phoenix swapped his 20 bulbs and told me his AC bill dropped another $25 a month in July and August. That\u2019s free extra savings you don\u2019t even think about. I didn\u2019t factor that in earlier because it\u2019s variable, but it\u2019s real\u2014if you live somewhere hot, that\u2019s a nice bonus.<\/p>\n

Wait, what about the upfront cost? I know some people hesitate because a single LED bulb is $3.50 vs $0.50 for incandecent, but let\u2019s do the payback period. For that same 10-bulb household: you spend $35 on bulbs. Monthly savings on electricity: ~$22 (since annual savings is $270, divided by 12). So payback period is like 1.6 months. 1.6 months<\/em> to get your money back on the bulbs, and then every dollar after that is pure profit. For the caf\u00e9: 12 bulbs x $3.50 = $42. Monthly savings: ~$27, so payback in 1.5 months. That\u2019s insane\u2014you\u2019re not waiting years to get your money back, it\u2019s almost immediate.<\/p>\n

I\u2019ve seen so many customers test this too. A guy in Chicago swapped his bathroom bulbs first (they\u2019re on all night for night lights) and saved $8 that first month alone. A small retail store owner swapped his display case bulbs (which are on 12 hours a day) and saw his electric bill drop $40 in the first month. It\u2019s not a scam\u2014this is real, data-backed savings.<\/p>\n

Now, let\u2019s talk about bulk swaps because if you\u2019re reading this, you\u2019re probably not swapping one bulb, you\u2019re swapping all of them. I\u2019ve worked with everyone from homeowners doing a whole house to small businesses, and the more you buy, the more you save on bulbs too. We don\u2019t mark up bulk orders\u2014we keep the price low for everyone because the biggest savings come from switching all your bulbs at once, not just one.<\/p>\n

Wait, let\u2019s address the \u201cbut my CFLs are already better\u201d crowd. Yeah, CFLs are better than incandecents, but they still have drawbacks: they take time to warm up, they have that weird blue tint, and they don\u2019t last nearly as long as LEDs. And in the long run, LEDs save more. Let\u2019s do that household example with CFLs: 10 bulbs x 14W, 3h\/day, 16 cents\/kWh. Electricity cost: 10 x 14W = 140W, 3h\/day = 511.35 kWh\/year = $81.82. Bulb cost: CFLs last 8,000 hours, so ~0.37 bulbs per year, $1 each = $0.37. Total annual cost: ~$82.19. So vs CFLs, LEDs save ~$34.81 per year for that household. Nothing to scoff at, but way less than vs incandecents. And if you care about e-waste? CFLs have mercury, so you have to dispose of them special. LEDs don\u2019t have mercury, so they\u2019re way easier to recycle (we even take back old LED bulbs for recycling for our bulk customers, just fyi).<\/p>\n

Now, let\u2019s get real\u2014no one wants to do all this math, so I\u2019ll give you a quick cheat sheet. For any bulb you replace with our LED round bulb:<\/p>\n
