Yangcsl 10W Dimmable LED Light Bulbs, E26 Color Changing Smart Light Bulb with 2.4G RF Remote Control (4-Zone), RGB & Daylight White (Pack of 4)

I've tried a handful of the cheaper to moderately priced 5-10W color changing led bulbs and I have to say this bulb has the brightest white light so far. The white is a cool color temperature. I haven't figured out all the buttons on the remote yet but I don't plan to as I mainly leave the color on white and occasionally change color when watching movies or entertaining guests. I paired the bulbs with ease and can control 3 bulbs separately with one remote. The memory feature on the bulb is excellent, and I'm able to toggle through white-> a dimmer white->to my last selected color by flicking the light switch off and on. Very happy with these at this time.

After about 1 month, one of the remote controls already doesn't work I tried changing the battery, but it doesn't solve the problem. The other remote still works, but the bulbs are in separate rooms, so this is not useful. I contacted the company and they immediately sent a replacement. Hopefully, this one will work longer than the original.

They work great. So long as they aren't hooked up to a circuit with a switch. If someone opens the switch the bulb and remote stop shaking hands, and have to be re-paired. I guess there's no NVM battery in the business end of the bulb. If not for that, then it would have been 5 Stars

Endless possibility for color. The customer service is exceptional. The remote confused me at first but they sent detailed and friendly instruction. Highly recommended.

Very dim. 1/8th the brightness of a phillips hue bulb. Remote operation is extremely confusing,

Read my comments on the last review. Not working as advertised as it stands and the instructions seem to be worthless. Open to amending this review if these are able to be set up right or replaced with ones that work as advertised.

Pasted from the one bulb page. I really think they should combine products onto one page with a Quantity Selection, and a Warm White/Cool White selection button.This is a 4th generation Yangcsl bulb I guess? I rated their 2nd gen 3 star due to issues found. They asked me if I wanted to try their 3rd generation which I liked. They sent me this bulb to try out as well. This makes me a shill..er..I mean...totally and completely unbiased and objective. I just got the bulb and wanted to give first impressions.The bulb claims 10 watts. It has a co-located RGB and a White LED, only one of which can be active at once to avoid overheating. Yangcsl is surprisingly honest, as many sellers "10 watt" are actually a 5 watt RGB and 5 watt white. This is NOT the case here. The white LED by itself appears to be at least 800 lumens which is the gold standard for a 60 watt incandescent. A lot of companies also fudge the "equivalence" and claim 7-8 watt lights to be 60W equivalent, which they aren't. They claim 880 lumens which seems fair and accurate, unlike many inflated lumen values claimed by less scrupulous companies.Lots of good points for Yangcsl so far.It is labeled as an E26 which is North American standard. I did notice that the heat sinking on this bulb is not as sleek as their 3rd generation Infrared. What this means is that it DID NOT FIT into my fan light assembly which has the typical "flower/cone" shaped glass shades. It likely dissipates heat better, but may have problems actually fitting. So I don't think this was a good tradeoff unless the RF chip required the extra space and heat sinking.The white mode is entered by the light bulb button top right and is dimmable in 8 increments. It goes down to pretty dim...say 5% power most likely. Furthermore, this one has a Night Light mode which drops it to 0.3%. I was not able to detect any PWM and I am quite sensitive to that. So their frequency is very high which indicates good dimmer quality. Cheap ones you can see flicker. I am shocked by the night light mode being so dim with no flicker.They say 5700K, but it feels closer to 5000K to me. There is NO blue tint at all with this light. 6k lights tend to have a significant blue shift. This is a tough subject to pin down however. The TL;DR is that the light seems perfectly WHITE with no offcast colors.IMPORTANT: You must RTFM to make this bulb work!!!! I really think the bulb should work out of the box, so I wasn't as happy with this. You MUST plug in the bulb. Then have the remote ready. Then turn off the wall switch or power. Then turn on, then tap D1 (or D2/3/4) FIVE times, giving about 3/4ths of a second inbetween each tap. If you did it right the bulb will flash twice white. NOT to be confused with the normal flash effect when the bulb changes color which it will be doing by default.NOW the remote will actually work... unless you accidently hit D2,3,4. In which case, press D1 again to reactivate.Above the bottom lightbulb thing there are 3 buttons, one for Red, Green, Blue. They used Fire,Plant, and Water to represent these. Remember that each one will be dimmer than expected because only one of the three RGB combo LEDs will be active. So 10 watts divided by 3 basically.The very top two buttons are the dimmer control. They also double as a frequency mod for the multicolor modes. The small one with 8 rays is actually the +brightness. The big circle is the - brightness. I would have done a + and - sign with with the 8 rays around it instead personally.There is a flash mode. It goes through several colors in sequence with no transition. The speed goes from really fast (0.15 second or so) to up to 3 second interval.There is a flash mode with a heart which you can program yourself. You can pick the color sequence used.Not sure how useful that is exactly, but its there. I can see this being good for when you want a very limited color palette such as shades of orange and red for halloween, or red/green for xmas, etc.NOTE: You cannot adjust the BRIGHTNESS of this mode which is kind of a bummer. However, if using this mode, you are doing a disco type effect, so you'd likely want full brightness anyways.There is a smooth transition mode that cycles through all colors. You can change the speed of transition but it is rather subtle. I could not really tell much difference if any. Instructions say a 7 second vs a 9 second transition. So not much of an adjustment at all.You cannot change the brightness of this mode, which IS a bummer. You might have 4 bulbs in a fan to use during the day as a bright light. But smooth transition at night would be wayyy too bright to be an effective nightlight.I would suggest the ability to change brightness instead of change frequency if at all possible in the next revision. I would also suggest more frequency change. From 7 to 9 seconds is a fairly meaningless adjustment.There are three preset color buttons. You press one and then you can use the 6 buttons to fine tune the color. Plus adjust brightness. I am rather amazed at this, but they did exactly as I had suggested (long before I suggested it) and you can control the relative contribution of EACH CHANNEL of RGB! This means you can pick ANY COLOR at all. The manual tries to help with this and even tells you how to get Pink, but best way to do it is google "RGB COLOR WHEEL". Use the color calculator to pick your color and note the hex code. Each of teh 2 digits refers to the Red,Green,Blue contribution. For example, if you max Red and Blue and minimize green you get deep Purple. Then, as you add Green, your purple becomes more pastel.I am shocked that they allow this level of control. I've not seen anything else like it.They have a timer mode that allows the light to turn itself off after X number of hours. Pretty cool, but likely not necessary as this is pretty power efficient.There is also a guy in a lounge chair button. Need to figure out what that does...My favorite features are the memory controls.First, it remembers EXACTLY which mode you were in when you turn off the light, either via remote OR wall switch,etc. It remembers the BRIGHTNESS ore frequency setting too which is quite important in my opinion.Secondly, when you turn it off and on within ONE SECOND (not 5 for sure), it will change operation modes. It changes to 100% white mode, then 20% white mode, then whatever mode you had it set to... smooth mode or a static color for example. It remembers your mode's brightness too.This is super cool because during the day you can toggle the switch and have 4 bright white bulbs for finding stuff. Then toggle it back to a "night mode" of your choice. Or toggle to the 20% white mode for evening light that is more subtle.I mentioned that 4 of these in smooth mode are overkill. So I recommend if you use 4 bulbs together (like in a fan), that you set ONE or two of them to smooth, and the other three to a really dim Red/Green/Blue static output. You will need to put the bulbs in separately to control them separately initially. You might need to set to Night Light mode, as even dimmest single color is pretty bright at night. You can also use their zone control to independently control each one in a cluster. Keep reading.Note that the remote is upgraded to a RF type. While the Infrared is ok for bulbs in one area (like 3 bulbs in a fan), the RF lets you control bulbs in a 360 degree spherical pattern. No pointing needed! This would be great if for example you had bulbs in several locations that you wanted controlled all at once. Like say you had ceiling can lights that used normal bulbs. This would be perfect.This is a nice upgrade and a good option to have available. It could backfire if you have multiple rooms with these bulbs, BUT this is why they have the zone options!You can set bulbs to belong to one of 4 zones, then one remote can control them by first clicking the desired zone, then control them.That was pretty long, but there it is. All in all, a great new revision and great listening to customer concerns. The above mentioned bits of honesty from this company have made me a fan.
