So no bulb is going to dim down to a real 1%. Yours dim down to 45%, perhaps higher than some others but not really out of line.
You need to set the dimming range of the dimmer so that it will only dim over the range suitable for your bulb. This will also insure that you’re not spending time “dimming” over a range where the bulb(s) won’t illuminate.
To adjust your range, go into the dimmer’s settings and set the minimum to 1 and the max to 99. Operate the dimmer and note the minimum value where the bulbs start to illuminate. Set the minimum to that value or thereabouts.
This will set the minimum dim to a pseudo 1%, which effectively lets you dim only over the range for which your bulbs will operate. If you have correctly set the minimum to a point or two above where the bulb(s) turn on, you now be able to set the dimmer to 1% and have a bulb(s) barely lit.
