Ceiling light wiring

I am replacing an existing flushmount ceiling light with a comprable LED fixture. Both are dimmable. When I removed the old fixture, I noticed there were 3 sets of wires in the connector box - 2 white, 2 black and 2 red(+ the ground wire). Both white wires were connected to the old light, 1 of the red and neither black (they were wired together and capped). Not sure if I should just replicate what had been done - had not seen red wires before. Name:  20160722_085242.jpg

Generally you would just replicate the way it was wired previously. You may have red wires for several reasons....three way switches or a multiwire branch circuit are two possibilities.

If the light was on a dimmer before, you may need to swap out the dimmer with one compatible with dimmable LEDs, but you can try the existing dimmer first (if there is one).

Reds can be used as a separately switched hot, while the black is a constant hot.

Just wire like the old fixture.
