Yangcsl LED Light Bulbs 85W Equivalent 1200lm, RGB Color Changing Light Bulb, 6 Moods - Memory - Sync - Dimmable, A19 E26 Screw Base, Timing Remote Control Included (Pack of 4)

These are definitely reliable. I like the fact that they all come with remotes. The remotes work really well. The lights function as they should. I like all of the colors. I think they need more dim, dull colors. But overall, I like it. You can customize it any color you want.

All 4 lightbulbs worked well and can all be controlled but the same remote-just point at the lightbulb. The colors are great and we like that each can be set to a different color. The bulbs are fairly bright.

I love how each bulb comes with a remote, and all remotes work for all the bulbs. So when we lose one, our break one, we still have remotes that work. These things are bright enough, but dimmable so we don't have to decide if we want bright or low light. And the best part... if we are going to bed and forget to turn off a light, we have the remote in bed and no one has to get up. As a bonus, the colors allow us to adjust the light when a migraine comes on.

Pretty decent, especially for the price. Bright. Just wish there was a white balance. Good bulbs though.

Gives such vibrant colors to the room, had it for some time and it’s still working just as good as when I got it! Just don’t lose the remote.

I ordered two four-packs and all bulbs were completely functional on arrival. I installed them within exterior enclosures, so time will tell how reliable they are when subjected to climate. Once installed it is so easy to walk around the residence and set the colors for a holiday or an occasion, and then reset back to plain illumination at other times. I was very pleased to find the bulbs remembered the last setting when powered off and back on. I don't know how long that memory lasts. I have not tried the timer functionality, since my exterior lights are already on a timer. Some notes I didn't see in the product description: the remotes use a standard 2025 battery (included) and have an easy slide-out tray for it; the rapid flashing feature only works for "white" light; both "white" light and the single color selections permit brightness adjustment in 3 or 4 steps, depending on color. I didn't think I would ever use rapid flashing, but I just realized it would be ideal if I was expecting a dinner delivery, I could just note to the driver to look for a blinking light on the front porch. I don't have the right test meter to check their lumens, but they are subjectively decently bright (somewhat dimmer in colors, as expected.) While I'm pleased for these as exterior lighting, I don't think I would choose to use them for interiors. The "white" light cannot be tuned, and there was some small variation in "white" color from bulb to bulb, which is noticeable when they are near each other. If I was designing this product, I would have allowed the "white" button switch between daylight, cool, and warm, since the bulbs are clearly capable of mixing colors. Overall I'm very pleased with this technology and this vendor, and I wish it had been affordable years ago. Now I have a bunch of single-color LED bulbs I have to give away.

I love these!! The fact you get a four pack for the price is awesome and I have installed them in my outdoor sockets! They're great for holidays because all I have to do is go out and use the remote to charge the colors!! Great quality, easy to use and remote comes with different functions for the setting on the lights! Love these

I purchased six of these bulb for outside lighting. As I see there are many questions regarding these bulbs I will provide more descriptive answers to many of the questions submitted here. These bulbs internally use eight white LEDs in a ring pattern surrounding four RGB LEDs in a center square pattern. The bulb is well constructed and has dimensions of ; Max Dia. 1.707in /43.36mm Length 4.673in / 118.69mm Using a Kodak 18% gray card I measure the color temperature at 5700K The remote functions well and allows easy control of all the bulb functions . Of the red, green, and blue LEDs of course the green looks the brightest since it is right at the peak color sensitivity of the human eye. Beware though the blue LEDs used in this bulb are actually brighter. The human eye is not as sensitive to blue so it just looks dimmer. You should not view the blue ( or any bright LED) at close range since you eyes will not respond effectively to protect your vision. Also in measuring the light output it was observed the blue LED output forced UV sensitive ink to florescence so there must also be some UV emitted by the blue LEDs. You will see in the tables below extended specifications for this bulb. Probably more than most will need however I feel there is something there for everyone. LUMEN Output Power Level W R G B Night light 0.32 - - - 1 12 15 32 48 2 134 23 49 73 3 247 31 66 97 4 358 39 83 122 5 465 47 100 147 6 627 55 117 172 7 736 62 134 198 8 839 70 151 223 9 966 74 160 236 WATTS CONSUMED Power Level W R B G Night light 0.45 - - - 1 0.5 0.7 0.7 0.7 2 1.2 0.9 0.9 0.9 3 2.1 1.1 1.1 1.3 4 2.9 1.3 1.3 1.3 5 3.6 1.7 1.6 1.6 6 4.8 1.7 1.8 1.8 7 5.6 1.9 2.0 2.1 8 6.3 2.1 2.3 2.3 9 7.3 2.3 2.6 2.5 Standby consumption 0.45 watt One year on standby consumes 3.94 Kilowatt hours Temperature rise white LEDs only base down power level Temperature rise 3 19F/11C 6 32F/18C 9 52F/29C 24 hour timer accuracy +- 12 seconds per day highly variable depending on ambient temperature and LED duty cycle Overall I really like these bulbs. I hope they work in cold weather better than the specifications state since my Christmas temperatures can be far below the -20C specification.

La distance IR est nul pourquoi pas RF qui est vraiment mieux, il faut toujours bien pointer la lumière avec la manette si non il risque d’avoir 1 sur 2 qui ferme pas ou qu’il change pas de configuration. sans compter la technologie de la manette. l’uminosité et la qualité ampoules est très abordable.
