Shuttle dimmer problems

With the shuttle dimmer it is not as easy as taking the wattage and dividing the load for LED lamps.

Two reasons for this:

1) Halogen lamps have a unity power factor and LED's lamps in general have a poor power factor unless you purchase the ones with a higher power factor the highest I have found is 95%
2) It may have a start-up inrush current or repetitive peak current during every half-cycle that makes it appear much worse, i.e. behaves like a higher wattage load

Secondly on the instructions shuttle only allows for one dimmer unit per light box due to heat

I have found that if I take the wattage of the dimmer and divided by the equivalent halogen rating this is the number of LED bulbs I will add to the dimmer.
