Single Color LED Bulb Lights

The biggest difference between LED and incandescent bulbs is how they make light. Incandescent bulbs heat a tiny wire until it glows, which wastes about 90% of the energy as heat. An LED bulb uses a semiconductor to make light, so it's five times more efficient and lasts up to 25 times longer. You get the same brightness for a fraction of the power cost, and the bulb itself runs much cooler, which is a big safety win.

You choose the color temperature based on the mood you want for the room, measured on the light bulb kelvin scale. For a cozy, yellowish glow like old incandescent bulbs, look for a 2700K or 3000K light bulb. For a clean, neutral white that's good for kitchens and workspaces, pick 4000K. For crisp, blue-ish daylight, you'd want 5000K or higher. Most of our residential bulbs are in that warm 2700K to 3000K range because that's what people are used to at home. Our guide explains more about what different light colors mean.

E26 and E27 refer to the screw-in base of the bulb. The 'E' stands for Edison Screw, and the number is the diameter in millimeters. E26 is the standard for 120V mains power in North America, while E27 is the standard for 220-240V in Europe and other regions. They're mechanically almost identical and often interchangeable, but you must match the bulb's voltage rating to your country's power grid. 

Yes, you absolutely can. A dimmable LED light bulb will work perfectly fine in a non-dimmable socket; it will just operate at 100% brightness. It doesn't hurt the bulb at all. The reverse is not true, though. Never put a non-dimmable bulb on a circuit with a dimmer switch—that's a common cause of buzzing, flickering, and early failure.

No, they don't. These are straightforward, direct-replacement LED bulbs. You just screw them in like any traditional bulb. There's no app, no WiFi pairing, no remote control. If you're looking for that kind of smart control, we have a whole range of WiFi smart voice LED bulbs that work with Alexa and Google Assistant.

CRI stands for Color Rendering Index, and it's a measure of how accurately a light source shows colors compared to natural sunlight. A high CRI LED bulb, typically with a CRI of 90 or more, makes colors look vibrant and true. Standard LEDs are usually around 80 CRI. You'd want high CRI for places where color accuracy matters, like in a kitchen, a retail display, or over a makeup vanity. For general lighting in a hallway, 80+ CRI is perfectly fine.

Both, actually. The miniature wedge bulbs in this category, like the 194/921/168 models, run on 12V DC. That makes them a great LED retrofit for RVs, boats, and landscape lighting systems that use a 12V transformer. They give off a lot less heat and use a fraction of the power of the old halogen bulbs, which is great for batteries and power supplies.

Those names describe the shape and size of the bulb, which affects how it directs light. A19 is the classic, pear-shaped bulb you see everywhere. BR30 (Bulged Reflector) is a floodlight bulb, common in recessed ceiling cans, that casts a wide beam. Candle-shaped bulbs, like our E12 or E14 models, are decorative and used in chandeliers or sconces. Choosing the right shape ensures the light goes where you need it.

No, you definitely shouldn't use it for regular room lighting. Our AC85-265V UVA bulb is a specialty tool that emits ultraviolet light at a 395-400nm wavelength. This is 'black light' territory. It's designed for tasks like curing UV glues and resins, detecting fluorescent materials in minerals or currency, or for special effects in entertainment venues. It produces very little visible light.
