I have a TGCL-153PH dimmer driving 5 Simba 6W LED blubs. I adjusted the control for good dimming range and the low brightness end is great. Trouble is at the high brightness end. The blubs flicker/strobe at high frequency. The adjustment level has no effect on the high brightness flicker/strobing. Solution now is to not move dimmer toggle to highest level, but is there a real solution?
