Review on 🌿 Chihiros C II Full Spectrum Dimmable LED Light with Bluetooth Controller: Ideal for Terrariums, Paludariums, and Nano Tanks up to 18 inches in Length by Joyce Swihart

This Nanotank LED flashlight is very bright and overall well made. It is suitable for nano aquariums up to 10 gallons. I've been using it for about a week so far. Here are some thoughts based on my experience. Advantages: 1. Adjustable arm. You can adjust the height of the light, ie distance from the LEDs to the top of the tank. You can also rotate the light from side to side.2. There is a simple application that allows you to connect the flashlight to your phone via Bluetooth. I use an iPhone and haven't had any issues with the light detection. There are manual and automatic modes. In Auto mode, you can schedule the lights to turn on and set the rise time, intensity level (0-100%) and fall time. Cons: 1. There are no instructions in the box. Two small rubber O-rings are included. I thought it was supposed to hold the metal arm in place. See attached photos.2. The photo featured on the Revain product page shows an application that appears to give you control over individual colors. In this light it's impossible. There are only white LEDs. This photo was a little misleading.3. There is no on/off switch. You must use the app.
