Have you tried measuring a White ambiance version of the bulb. The one which has 575lm?
Hmm it’s connecting to ZHA, and then out of nowhere after few secs it is unavailable, tried to add some custom quirks there, but without any success…
I was not able to add it with Zigbee I do have the Kajplats 806lm
at the end I configure it with matter 
I was curious to try z2m before but I did actually switch from zha exactly to pair this bulb.
Nvm, upgraded my old sonoff zbbridge to Home Assistant ZBT-2 and it works.
I have the same bulb, firmware 1.0.28. Even with the script i could not get it connected. Moved it besides the controller (sonoff) that did not work. It only got connected when i initated a touchlink scan when the bulb was in paring mode…
i can confirm i got it working (a KAJPLATS E27 bulb, white spectrum, globe, clear, 470 lm (LED2411G3)) with 15x poweroff/on with following setup:
- Zigbee2MQTT docker latest version (i have HA also in docker
) - SMLIGHT SLZB-06Mg24 over ethernet.
In earlier attempts i tried the 6x power-cycle. But after 15x It connected to Z2M just by pushing the “Join Allow” button.
The bulb seems fully supported now… 
This worked like a charm ! The video sure helped me to get it working.
thx!
I was able to connect all my bulbs, but the Big Filament ones were tricky (only 2 of 4 worked).
The only problem I have with the connected ones is that the red is totally off. It is Pink and not Red. Not sure if it’s the bulbs or because I connected them via Zigbee. Anyone got the same problem?
I’m using Zigbee gateway ConBee II:
Kajplats just work super fine, as they were Philips Hues (which are explicitly super Zigbee-compatible).
I compared the benchmark of Kajplats vs Hue Essential which leaves no doubt in favour of Ikea (both quality and price. mind that Essentials already cost a third or a half of top-line Hues).
Integration was quite easy: at the 12th power-on, the bulb went into pairing mode and HA revealed it through the gateway.
I confirm every part you’d want to use of Zigbee protocol is still supported as with other bulbs provided by other vendors.
All of this leaves me no choiche other than filling my home with Kajplats!
Thanks @dwd for the script. Worked like a charm, bought KAJPLATS E27 1521 lm today, converted in one go. My local IKEA supposed to have older TRADFI in stock but apparently they were nowhere to find and I was in hurry to buy a replacement for a faulty one. Let’s see how will it behave as a router. I have another 3 devices at distance so this will be a “proxy”.
