Nice bright yet warm lighting. Fit my can lighting with no problems. Read more
The media could not be loaded. 3 year review. We bought the 16 pack of LED bright white flood lights in 2022. They are great and light up the house nicely. We bought another 16 pack for more ceiling lights soon after. After 3 years of 32 lights, 2 finally started to flicker. The sunco website was easy to get warranty replacements. As a bonus, they are sending 2 additional bulbs for good measure. The difference between a good company and a bad company is how they support their products years down the road. I definitely recommend them and will keep buying their products. Read more
2023-01-23. Sunco BR40 LED light Bulbs. Dimmable, 3000K Warm White, 100W equivalent, 8PK. In today's day and age, incandescent bulbs are a thing of the past. They're energy hogs and they get really hot to the touch. LED's (Light-emitting Diodes) are not new, they've been around since the 1960's. Back then they only produced red light. By the mid 1970's a version emitting green light was established and by the 1980's yellow LED's were available. But it wasn't until the 1990's that ultra bright LED's were available in an array of colors. Since then LED'S has been one of the most rapidly growing technologies, and today the spectrum of light produced by LED's includes Ultra Bright White light (daylight). LED technology continues today, but towards the other end of the light spectrum towards the pure violet and ultra violet ("black" light). There are two main things you need to know about LED's: Color Temperature, and the Color Rendering Index or CRI. There is actually a third factor about LED lighting, and that's lumens, but that's a topic all on it's own. To keep things simple, the higher the lumens, the more powerful the light is (intensity and distance); however, lumens is not universal. If you're going to consider lumens, make sure you check for ANSI Lumens as those values are standardized (ANSI = American National Standards Institute). Color Temperature. The color of light is measured in Kelvin degrees, hence color temperature. The range is from 1,000°K (Orange) to 10,000°K (Blue). The spectrum is as follows: 1,000°K = Orange 2,000°K = Orange Yellow 3,000°K = Yellow 4,000°K = Light Yellow 5,000°K = Faint Yellow 6,000°K = White 7,000°K = Faint Blue 8,000°K = Light Blue 9,000°K = Blue White 10,000°K = Sky Blue But that's not how these are marketed. Commonly used names in the Kelvin scale are as follows: Warm White – 2700K to 3000K (close to standard incandescent bulbs) Soft White/Warm White – 3000K to 3500K Cool White – 4000K to 5000K Daylight – 5500K to 6500K (starts to appear blue in color) Color temperatures are important because it sets the mood or atmosphere of the room. Think about the space you want to light up, then decide the mood you want to set for that space. Soft White Light Color: Calming, Cozy, Warmth, Inviting Cool White Light Color: Clean, Neat, Vibrant, Fresh Daylight Light Color: Alertness, Focus, Sterile Most people will probably not want their bedrooms to be filled with a bluish sterile light. Conversely, you probably wouldn't want your dentist using a warm orange light when repairing a damaged tooth. The point is certain LED light colors work best in specific environments. If you don't know which color temperature you want, here are some general guidelines: Soft White and Warm White (2,700°K - 3,500°K) LED colors give a calming and relaxed feeling. Common uses for this would include residential spaces like bedrooms, bathrooms, closets, dens, and dining rooms. Cool White (4,000°K - 5,000°K) LED colors give a brighter and fresher feeling. Applications would include larger areas like kitchens, living rooms, garages, attics, and unfinished basements. Daylight (5,500°K - 6,500°K) is probably as bright as you should go in a residential application, and there are not many spaces for this type of lighting as this type of lighting often induces alertness and focus. Areas for daylight would include spaces like the home office or a workout area. Daylight would also work for things like display cases if you're trying to show off any prized medals, awards, or trophies. Since color temperatures alter how a space is perceived when illuminated, it’s important to consider the surrounding. LED Light colors help to add a layer of depth, and in providing illumination, can highlight surfaces and materials. When considering a space ask yourself what the space is for, who’ll be in the space and what overall mood you want to create and experience. Now the second thing I mentioned was CRI or Color Rendering Index. This is essentially how the color looks under a light source when compared to viewing it under sunlight. Not all light produced by LED's are created equal. If you're ever had trouble discerning a navy blue sock from a black one, the culprit could be that the lighting has a low CRI. The CRI scale is from 0-100, with 100 meaning that the color under the light source is identical to that as if viewed under direct sunlight. In general a CRI of 80+ is sufficient for most applications; for applications where color presentation is important, you may want something higher to ensure your colors "pop" or you pictures are vibrant and full of life. A CRI of 90+ is considered to be "high". High CRI lighting is equally valuable in home use as it can transform a room by highlighting design details and creating a comfortable, natural overall feel. If you're wondering why I'm not talking about Wattage, it's because wattage has nothing to do with light. Wattage is a unit of power (Watts = Volts x Amps), it's the amount of electricity consumed when the light is on. While we often conclude that a device requiring more power generates more output, it was never the case. This applies to most things, speakers for example often are described in Wattage; however sound levels are really measured in decibels. Heaters is another thing often described in Wattage while output of heat is measured in BTU's (British Thermal Units). The list can go on, hair dryers, microwave ovens, water heaters, radiators, and of course light bulbs... With all that said, you should now be able to draw your own conclusions with regards to the type and quality of light these bulbs will produce. Think about your use, your space, and the atmosphere you want to create and from there you can determine if these bulbs are a good fit. The one thing I can tell you is that I've installed three of these bulbs in my second floor hallway and 2 of them stopped working after only a couple of months. They do offer a 5-year warranty (which is really nice), but I didn't exercise it because my replacement bulbs have yet to give. So far, it's been about 8 months and the one bulb I installed on day one is still without issues. Read more

Imagine swapping out every bulb in your house for a slice of sunshine. That's exactly what I did with Sunco's LED bulbs, and boy, did it brighten up my life - literally and figuratively. These 5000K daylight wonders are like having mini suns floating from your ceiling, minus the sunburn and existential dread. Let's start with the good stuff. These bulbs are brighter than my future after a good therapy session. They perfectly mimic the natural light streaming through my windows, creating a seamless indoor-outdoor vibe that's great for battling the blues of Seasonal Affective Disorder. Plus, they play nice with my Leviton dimmer, allowing me to set the mood from "interrogation room" to "romantic cave" with ease. Now, about that dimming - it's smoother than a jazz saxophone solo, but with a slight hum. It's like the bulbs are trying to sing you a lullaby, but they missed a few music lessons. Not a deal-breaker, but worth noting if you're sensitive to sound. The energy savings? Oh, it's like going from a gas-guzzling SUV to a Tesla. Running six of these bad boys at 17 watts each instead of 100-watt incandescents makes me feel like Captain Planet. While I can't confirm exact savings on my energy bill, my eco-guilt has drastically reduced. However, here's where things get a bit dim. Sunco claims these bulbs will outlive your pet tortoise with a 22.8-year lifespan. Spoiler alert: they won't. Unless your days are 3 hours long and you only use lights once a week, you're looking at a much shorter lifespan. In my real-world test (aka living my life), I'm replacing 3 out of 8 bulbs after just one year. It's like they're playing a game of "survival of the fittest" in my ceiling. This brings us to quality control. Are these bulbs made from papier-mâché? They feel about as durable as my New Year's resolutions. While they look sleek, one fumble during installation, and you might be sweeping up LED confetti. On the bright side (pun intended), they're a breeze to install - if you can screw in a light bulb, you're overqualified. In conclusion, the Sunco BR40 LED bulbs are like that friend who's great at parties but sometimes flakes on you. They'll light up your life with their brilliant daylight glow and energy efficiency, but their durability and longevity claims are about as solid as a sandcastle at high tide. If you're after that perfect daylight ambiance and don't mind playing bulb roulette every now and then, these might just be your luminary soulmates. Read more
