A II 401 – Bluetooth-controlled LED lighting

The Chihiros A II 401 is a Bluetooth-controlled LED lamp for planted aquariums 40 cm wide. It suits keepers who grow demanding aquatic plants and want to set the light intensity by time of day, instead of running a fixed timer.

Why it matters

• Forty SMD HCRI diodes deliver 1700 lm at 15 W, with a color temperature of 8000K.
• Light intensity can be assigned to each hour of the day in the My Chihiros app, which is available for Android and iOS. Sunrise and sunset times can also be set.
• The manufacturer rates the LED lifespan at over 50,000 hours, compared with 30,000 hours for the previous generation of diodes.
• The lamp's photosynthetic output (PAR) is stated to be comparable to T8 and T5 fluorescent tubes.

What it works with

The lamp is intended for planted aquariums 40 cm wide, where its 8000K output and 1700 lm flux support plant growth. Adjustable legs rest on the tank rim, and the clamps fit glass from 4 mm to 8 mm thick. Because control is limited to the app on a smartphone or tablet, a compatible mobile device is required to program the lighting schedule.
