(More customer reviews)LED dimming often requires matching the dimmer to the lamp. Many lower end dimmers flicker with LEDs. The 6613 is a magnetic low voltage "MLV" dimmer designed primarily for use with transformer loads but it seems to work quite well with Sylvania PAR LEDs.
Testing showed that MLV dimmers worked better at reducing LED flicker due to their more precise phase control. Non-MLV dimmers often produce highly asymmetric waveforms when dimmed (with more voltage on one side of the waveform) causing the LED to flicker on alternate half-cycles.
Before installing the Leviton 6613 I tried the Lutron Diva DVCL-153. The DVCL-153 is specifically made for LEDs and CFLs and features a low-end preset trim under the cover. The DVCL-153 is not an MLV dimmer. Unfortunately, the Lutron DVCL-153 flickered and was also interfered by other DIVA MLV dimmers in the wall box. The adjacent dimmers were on a separate circuit and there was no shared neutral.
I replaced the Diva DVCL-153 with the Leviton 6613. The Leviton 6613 worked flawlessly with Sylvania/Osram PAR-30 and PAR-38 LED lamps.
The 6613 has good low end dimming (though not to full black) with no "pop-on." When switched from both the dimmer or alternate "three way" switch, turn-on at all levels was consistent. The low-end dimming performance is the best I've seen. Although the 6613 has no low-end preset it does not appear to need it. There was also no adjacent dimmer interference with the 6613. The load was 2X PAR-30 (15W each) and 1X PAR-38 (18W).
I highly recommend the Leviton 6613 when paired with the Sylvania LED PARs. With other lamps "your mileage may vary" but the 6613 would be my first choice for tests.
