switch for dimming 2500W resistive loads (lighting)
If you want to avoid the hysteresis effects of dimming bulbs at turn on, I would use precision phase controlled pulses with a small pulse transformer that does not depend on load resistance for trigger current and thus narrow angle pulse triggers into SCR’s.  this is comparable to gate pulse triggers on 500V rated FET’s but more expensive.
It all depends on your design skill and volume.  When I did it in mid ‘70’s , I made my own pulse transformers. X 8 channels.
But keep in mind a 100W bulb if triggered on peak sine when cold, the current is 10~20x for one cycle as it decays when hot.
