That is more in keeping with the tradition of Tenebrae being conducted about 4:00 am - pre-dawn, the dawn symbolizing Christ, the light, so the final candle coming back to light is somewhat coinciding with the coming of real dawn.
I guess parishes are doing it in the evening for practical reasons, much easier for families to get to church then than at 4 am, but it loses some effect that way, some of the symbolism.
You’re not going to get much turnout in a suburban parish for a 4 a.m. service, and certainly nobody with children, especially on a weekday. However, we can start about 6 a.m. here, and be finished before sunrise is visible.
