Tapo L535E Smart Color Bulb Review: Warm, Dimmable Light for Winding Down
Key Features
1100 Lumens, Properly Bright
Most smart color bulbs stop at 800 lumens. The L535E pushes 1100, so one bulb actually lights a nightstand or a small room instead of just glowing at it.
Warm White Down to 2500K
Dial it to a low 2500K amber in the evening, then cool 6500K daylight in the morning. The warm end is orange enough to read under without feeling wired.
Matter Certified, No Hub
Works with Alexa, Google Home, Apple Home and SmartThings, and keeps running on your local network if the internet drops. No separate bridge to buy.
Schedules and Timers
Set both bulbs to fade to dim amber at 9pm and shut off later on their own. Build the wind down routine once and you can forget it’s there.
Our Experience
We put a pair of these on the nightstands to replace some dumb LED bulbs that only did one flat shade of white. First thing you notice is the brightness. At full blast a single L535E genuinely lights the corner of the room, and that 1100 lumen figure isnt marketing fluff. For a bedside bulb you’ll almost never run it that high, but it’s nice knowing the headroom is there.
The part that matters for sleep is the warm end. Drop it to around 2500K, pull the brightness down to maybe fifteen percent, and you get this low orange glow that’s easy to read under without feeling switched on. I set a schedule so both bulbs slide to that warm setting at 9pm, and after about a week it started to feel like a cue to put the phone down. Small thing, but it stuck.
Setup was the easy part. Matter meant I scanned the code in the box with Google Home and both bulbs showed up, no extra account needed to get going. Where it gets annoying is reliability. Every so often Alexa loses track of one bulb and I have to poke it through the Tapo app to wake it back up. Not a dealbreaker at ten bucks a bulb, but worth knowing if you run everything through Alexa. Apple Home folks seem to have a rougher time of it, going by the reviews.
Color holds up better than I expected. The 90 CRI rating means reds and blues actually look like reds and blues instead of washed out pastel, which you dont always get on cheap smart bulbs.
Pros & Cons
What We Liked
- Two bulbs for about twenty bucks, enough to do both nightstands at once
- Real 1100 lumen brightness that dims down smooth to a low amber
- Matter setup took under a minute, scanned a code and it was in Google Home
- 90 CRI colors look accurate, not the washed out look you get on budget bulbs
Worth Knowing
- Alexa and the Matter link drop now and then, the Tapo app is the steadier way to control them
- Apple Home pairing is hit or miss for some owners
- At the very lowest dim it could go a touch warmer for my taste

The connection can get flaky on Alexa, so keep the Tapo app on your phone as backup.
