Chihiros Adjustable Holder for A II Series Lights — Extending mount that lets an A II light span a longer tank
The Chihiros A II sits on fixed acrylic supports, so each light fits one tank length exactly, and a 30 cm light looks lost on a 40 cm tank. Chihiros Adjustable Holder for A II Series Lights (SKU: D-CA2-AdjustmentHolder) is Chihiros’ adjustable mounting holder for the A II range, made so the length of the mount can be changed and the same light can sit across more tank sizes. Australian retailer Nature Aquariums lists a 10 cm bracket and gives the example of an A II 30 cm light fitted to a 40 cm tank. The light itself is sold separately.
Standard A II lights come with transparent acrylic legs that clamp onto rimless glass up to about 8 mm thick, and with those legs fitted the light measures its nominal length, for example 300 mm on the A II 301. The adjustable holder takes the place of those legs when the tank is longer than the light, which is common with odd sizes, older tanks and second-hand lights moved to a new aquarium. It is also a straightforward replacement when an original leg has been broken. The holder is listed for the A II series as a whole rather than for one length, and the A II lights it carries are made for planted aquariums. European distributor Aquasabi notes that A II lights are not suited to running under a closed aquarium lid.
Usage & Application
When to Use
- Tank longer than the light: Spanning a gap such as a 30 cm light on a 40 cm tank.
- Moving a light to a new tank: Reusing an A II on a different-length aquarium.
- Broken acrylic leg: Getting a light back on the tank after a leg has cracked.
- Odd-sized tanks: Custom or older aquariums that do not match a standard A II length.
Installation & Setup Guide
- Switch off first: Unplug the light and lift it off the tank before changing the mount.
- Remove the standard legs: Take off the acrylic supports from each end of the fixture.
- Fit and extend: Attach the adjustable holder and set it to the tank’s outside length.
- Check the seat: Make sure both ends sit square on the glass before switching on.
