What is your original bulb specifications?

Easiest step is just remove it and let it empty.

Or change to smart led where u can control with WiFi.
Some smart led bulb can control colour brightness thru app

If bedrooms. Consider low Kelvin rating. Higher ones are harsh. Especially at night.

I use 4 x 3000K 6" Philips Meson square downlight for my bedroom. 1 switch controls a pair. I normally just turn on a pair and seldom use both pairs

However, I turned them off completely post 9pm and use auxiliary Ikea Tagarp placed next to my bed. 2 sets of bulb give me selection flexibility for low lumens bulb.


This setup suits my usage pattern and kinda works for me. It may not suits you but I'm just sharing. 

I realize the downlight can't do much so I need some auxiliary lighting.

Downlight with adjustable brightness could work for you though.

Bro, this photo you shared is actually PHILIPS 6" Downlight 1200lm. If 5" it is actually only 900lm.
What color (CCT) you using? 6500K?

Without knowing the original specifications, not easy to advise you what to get.
PHILIPS very standard:
5" = 13W/900lm
6" = 17W/1200lm
8" = 24W/1750lm

The newer series comes with IO (interlaced optics) which reduces glare.
Daylight (6500K) in my opinion not suitable for bedroom. Go for neutral white (4000K) or if you can take it got for warm white (3000K).
