Bulbs are now being sold with either 4m flash or 1m flash. Each model is slowly being moved from 1m to 4m. Any bulbs with 4m flash will say (4m) after the model number printed on the bulb. You will also be able to tell using a binary sensor on the bulb called 4MiB, or by the amount of Free Space for OTA indicated on the web interface. 1m models will have under 500,000 bytes free, while 4m models will have almost 3,500,000 bytes free.
As of November 2024, only BR-30 bulbs are being sold with 4m flash. A21 bulbs will probably start being sold with 4m flash in approximately February or March of 2025.
Make sure you download the appropriate 1m or 4m version for each individual bulb below.
