The schedule can be advanced or delayed. In DIY mode, Cycle Color has no time or brightness selection. The claimed 20–25 cm tank length is the relevant stated size range.

- Adapter (Included)

## A good fit for

- Owners of a 20–25 cm fish tank seeking a clip-on light with a preset daily cycle.
- Buyers who want to select from listed colours, brightness levels and timed DIY operation.

## Less suited to

- Buyers whose tank is outside the stated 20–25 cm length range.
- Anyone who needs the light to stay on throughout the night, since the scheduled mode turns it off for part of the day.

## Customer feedback

Customer feedback evidence is limited to aggregate ratings, which lean positive but also include a one-star share. The small rating sample cannot establish which features buyers liked or explain the low ratings, so treat it as a limited signal rather than evidence of performance or reliability.
