LVWIT Smart Light Bulbs Alexa, BR30 100W Equivalent, E26 Smart LED, Work with Google Assistant, Smart Life App, Tuya App, Dimmable 1300 Lumens RGB Color Changing Bulb (13W), No Hub Required, 4-Pack

I've purchased several of these smart bulbs from multiple vendors for a very long time - and by far this is probably the BRIGHTEST of all - almost as bright as a Non-Smart Philips traditional LED bulbs.There are a few times, the (some) bulbs won't respond to ALEXA (turning off) or takes several seconds to do so. And sometimes - if you manually turn OFF and ON the switch - non of the bulbs won't respond. It requires at least a 3-4 seconds between OFF / ON operations.Other these two quirks, I find them really awesome and am planning to buy more of these.

I bought this for can lighting clusters (group of multiple can lights controlled by a single switch) in my house. I actually have 3 clusters (kitchen, master, living room).I had previous bought a different brand, I had to replace with these, which worked better.There appears to be an issue I am having with the can clusters where the power can become intermittent on off every month or 2. This causes the lights to go into PAIRING MODE.The issue with the previous brand I had there been no way to get out of it unless you re-import into your Smart Life app. This was bit of a pain each time it happened.However, with these brands, when it occurs and goes into pairing mode, you just turn off the lights for a few seconds, turn it back on and it gets out of pairing mode. So, I ended up replacing all my lights with these. Was quiet expensive given how many lights I had.Generally speaking, I am very happy with these lights. There is one odd issue though.When there is a cluster of 4 lights, it works fine.When you go up over that (like 6 and 8 in my case), the dim does not work right unless you leave 1 light at close to max brightness. What will happen is all the lights will flicker until you raise the brightness on one of them to the max. I guess the flickering is to notify that there is an issue (or pairing mode perhaps I'm not sure).I would have liked to not have to have 1 can light at super high brightness so entire room can dim low properly. But I'm happy with it overall. I don't know if the weird issue is with the bulb or the wiring in my house causing this condition. It would be interesting to see what others post. Maybe I will upgrade in a few years to see if there is something better.On energy efficiency, I'm not sure, but our energy bill did go up quite a bit. I don't know if the wireless communication is taking extra wattage. I will wait and see and update the review.

Out of the box one of the 4 wouldnt change colors, but they paired and seemingly worked well for 3 weeks. After about 3 weeks I turned them on and they would flash on and off signaling they needed to be paired again. I did this, and after another few days of them working they started over again needing to be paired again. Terrible product.

Absolutely wonderful , super easy install, synced with Alexa easily and best of all very bright . My kitchen is much brighter.

Brightness, consistency and reliability have been very good. Work well with my Google Home setup, but the app they require isn't as good as let's say Hue. Color tones not as good as newer Hue lights, but cost is a lot better.

Love these two exactly as they are advertised no issues connected extremely easily works great with Alexa

I bought 8 of these bulbs, and within a couple of months of setup, 2 of them lost their connection to the home network. I have followed the reset instructions from LVWIT, but no matter what I do, these two bulbs will not enter pairing/discovery mode. They just blink endlessly, so I can't even use them as "dumb" bulbs. A 25% failure rate is pretty bad, so I would avoid these.

The lights flicker at a very high frequency when dimmer (leviton) is turned to high. Synced the lights to my smart life app. Some of the bulbs respond to color changing and some of the don't. Grouped the smart bulbs to one room and only a few of the bulbs change when changing the colors and scenes on the app. The bulbs switch from which one changes correctly and doesn't so it isn't one bulb that is the problem. Will be returning these ASAP.
