Yeelight Bulb Color dim

Yeelight LED Bulb (Color)

After firmware update the color mode in bulb is way to dim on max brightens.

Would like to back to old firmware if possible.

Just bought Yeelight Smart Led Bulb W4 L. It’s way too dim on max brightness in color mode. I have a IKEA TRADFRI RGB light bulb it’s 806 lm too, it has the same brightness on white mode, but definitely brighter than W4 L.

Here’s the pictrure of the bulb turned off.
Here’s the W4 L White, Red.
Here’s the TRADFRI White, Red.

Did someone experienced the same?
