These are by far the most popular traditional downlights that people will be familiar with. The most common ones (HV-FD) have a standard light output of 600Lm. They have no driver and are very easy to control using standard Triac wall dimmers. If you need even more light you can choose the LV-CRI97 range which can also be connected to several central dimming systems (Dali, 1-10V, Casambi).
The CRI97 will give your interior much more detail because of the special phosphor mix in the LEDs. Both technologies have a warm dim version so the light gets warmer the more you dim it.
