The super dimmer it is certainly better than the normal dimmer you are using now.
It would be better, however, to try to prove it. Let’s see how it works circuits.
The working principle.
The super dimmer circuit is shown in figure 1 is a circuit that would be good. Start with capacitors C1 and R3 reduce a level AC voltage to, diode D1 and D2 rectifier as DC voltage. Both zener diode ZD1 and C2 are maintain the regulated voltage, and this voltage will be applied IC1-555 timer,it is set as the monostable multivibrator, by have TR1-TR3 generate a pulse to trigger (pin 2) of IC1. The time period output of IC1 can adjust with VR1 and VR2
Figure 1 The complete circuit of supper dimmer.
When trig pulse is “0” C3 will start to charge pass through R5, VR1 and VR2. While C3 is charging at output of IC1 will have level is hight or the same level as the A1. Makes the triac does not conduct current. When C3 charge until fully output of IC1 will drop as “Low”. Makes the triac conduct current Depending on the time constant of C3, C5, VR1 and VR2. If the time constant much, time that triac conduct current fewer. But if time constant lower the time period conducting of triac much. Which depends on the VR1 and VR2 there. They L1, R7 and C5 are the high frequencies filter circuits because switching of triac.
How to builds
The Single-sided PCB layout is shown on figure 2 and Component layout for the PCB is shown on figure 3. When we use the triac number TIC-206 So can be used within 600 atts. If you use more than this. Need to change the another number. Resistant want that currents. L1 can be made by taking the AM radio ferrite rod was cut to about 5 cm, then, using enameled copper wire # 20. Fully around the core, then coated with varnish.

Figure 3 the Component layout for the PCB
At first, connected load is lamp at output then enter AC line 220V to the circuit. Adjust VR2 clockwise until then adjust VR1 to lamp go out. And then try to gradually adjust VR2 clockwise, to observe the gradual illumination lamp. And brightness, adjusting VR2 completely. Adjust VR2 then if abnormal, repeat from the beginning, but the VR1 on the other hand.
