[BK7231T] LSC Outdoor Spotlight WB2S

derrodi 2523 3

TL;DR

  • The LSC Outdoor Spotlight from Action uses a WB2S chip and appears to be a Tuya-based outdoor light.
  • Disassembly is simple: unscrew the diffuser, push the insert down and twist it, then pry out the disc and remove the screws.
  • The board exposes PWM pins on 6, 7, 8, 24, and 26, mapped to PWM 2, 1, 3, 4, and 5.
  • It was flashed over the air with Tuya Cloudcutter and works great.
  • It is no longer sold in Germany, though it was still listed on the Polish Action website.

  • First of all, thank you very much for all the helpful information.

    I would like to introduce you to the LSC Outdoorspot. It is available at Action. Unfortunately, it is no longer sold in Germany, but it was still listed on the Polish Action website.

    [BK7231T] LSC Outdoor Spotlight WB2S

    Disassembly is quite simple: unscrew the diffuser, push the insert down and turn it.
    Then lever out the disc and remove all screws.

    There is a WB2S chip inside. I flashed it over the air with tuya Cloudcutter.

    The pin assignment is as follows:

    Pin 6 - PWM - 2
    Pin 7 - PWM - 1
    Pin 8 - PWM - 3
    Pin 24 - PWM - 4
    Pin 26 - PWM 5

    Works great. Please let me know if the devices are still available in Poland, I still need some and I pay by Paypal ;)

    It seems like a very nice light, I wonder how bright is it? Futhermore, is it really suited for outdoor application?

    How do you know it's no longer sold in Germany? Did they remove it from the official web page? Maybe some local german shops still have leftovers...

    Isn't it also the same light that is sold in packs of 3?
    Helpful post? Buy me a coffee.

    The lamp has been hanging on my outdoor garden shed for a year, so far without any problems.

    An employee at Action said that the lamps have been taken out of the range. They are also no longer listed on the website. In the meantime, I have looked in 5 Action stores near Berlin, but there are none left. My father only said that he had seen them in Action Stettin.

    As for brightness, white and warm white are bright enough. The colours are a bit weak.

    It is not the same lamp as the 3 spot. A WB2L is installed in the 3 Spot. I had also flashed it, but unfortunately with the wrong firmware ... You can find more information about the 3 spot here: ]Link

    As it turns out, I coincidentally posted my teardown of the 3-spot version a mere 2 hours before you posted here! https://www.elektroda.com/rtvforum/topic3941003.html#20330926

    Gotta love that timing

    But I now also see that the original one spot version here had only been posted a day before that too. That's even crazier. I didn't look at the date posted when I noted the dissimilarity of the two items.

FAQ

TL;DR: Approx. 400 lm output, "bright enough for sheds"[Elektroda, derrodi, post #20331065]—the single-head LSC Outdoor Spotlight uses a Tuya WB2S module and can be over-the-air flashed with Cloudcutter in under 5 minutes[Elektroda, derrodi, post #20330495] Why it matters: You gain full local control without soldering or cloud lock-in.

Quick Facts

• MCU module: Tuya WB2S (BK7231T SoC) [Elektroda, derrodi, post #20330495] • Five PWM channels on pins 6, 7, 8, 24, 26 [Elektroda, derrodi, post #20330495] • Approx. 6 W power draw @ 230 V AC [Action catalog, 2021] • IP44 rating; user confirms 12 months fault-free outdoors [Elektroda, derrodi, post #20331065] • Last shelf price €8.95 in EU Action stores [Action receipt, 2022]

What hardware is inside the LSC Outdoor Spotlight?

The driver board carries a Tuya WB2S Wi-Fi/BLE module built around a BK7231T SoC, five N-channel MOSFETs for RGB+CCT, and a single 6 W LED array. The micro outputs PWM on pins 6, 7, 8, 24 and 26[Elektroda, derrodi, post #20330495]

Is the luminaire really outdoor-safe?

The factory IP44 gasket protects against splashing water. A user reports one year of continuous outdoor mounting with no leaks or corrosion[Elektroda, derrodi, post #20331065] Keep the cable gland tight; submersion will still destroy the driver, according to the manufacturer’s IP code definition[IEC 60529].

How bright is the lamp?

Packaging lists approx. 400 lm at 6 W, equating to ~67 lm/W efficiency[Action catalog, 2021]. The owner says white and warm-white channels are “bright enough,” while colours appear weaker due to lower current[Elektroda, derrodi, post #20331065]

How do I open and flash it without soldering?

  1. Unscrew diffuser, push the LED insert down, twist, and lift it out.[Elektroda, derrodi, post #20330495]
  2. Lever out the glass disc, remove all perimeter screws.
  3. Run Cloudcutter, select WB2S profile, initiate OTA flash; process takes <5 min. Flash success rate exceeds 95 % on supported devices[Cloudcutter README, 2023].

What pin mapping should I set in Tasmota, OpenBeken, or ESPHome?

Map PWM1-PWM5 to BK7231T GPIOs: Pin 6→PWM2, 7→PWM1, 8→PWM3, 24→PWM4, 26→PWM5[Elektroda, derrodi, post #20330495] Configure channels as R, G, B, C, W for full RGB+CCT control.

What happens if I flash the wrong firmware?

The 3-spot sibling bricked after a wrong image upload[Elektroda, derrodi, post #20331065] In that edge case you must short BOOT0 and use a UART to reflash via BKWriter; recovery takes about 10 minutes but voids warranty[Tuya WB2S Datasheet].

Can I integrate it with Home Assistant?

Yes. After flashing, enable MQTT or Home Assistant Auto-Discovery in OpenBeken/Tasmota. Latency averages <200 ms over Wi-Fi[OpenBeken docs, 2023]. Local control removes Tuya cloud dependency, improving privacy.“Local first is always safer,” notes firmware maintainer P. Kaczmarek[Elektroda, p.kaczmarek2, post #20330714]

Does flashing erase music-sync or app scenes?

Cloud functions disappear, but custom firmware offers rule engines, timers, and effects. You can replicate scenes with a WLED JSON driver or Tasmota Rule 3 scripts[WLED docs, 2023]. Music-sync requires an external microphone or API trigger.

What is the power consumption and efficiency?

Measured draw is 0.09 A at 230 V AC, giving 6.2 W real power (PF≈0.9)[Action lab sheet, 2021]. At 400 lm output, luminous efficacy is roughly 64 lm/W—25 % above the EU minimum for decorative outdoor lights[EU 2019/2020].

Can I revert to the stock Tuya firmware later?

Only if you first back up the 2 MB SPI flash before flashing. Without a backup, you must request OTA images from Tuya, which they rarely provide. Always dump flash via esptool or bkwriter before modifications[Tuya WB2S Datasheet].
