1. What is the main difference between the Chihiros WRGB II and the WRGB II SLIM Edition?
The SLIM Edition features a much thinner housing profile (0.7 inches) and operates at roughly 40-50% reduced PAR brightness compared to the standard WRGB II. It is designed specifically for low-to-medium light planted tanks, mosses, and epiphytes to reduce algae risk while maintaining vivid WRGB color enhancement.
2. Can I schedule sunrise and sunset ramping on the SLIM Edition?
Yes! Built-in Bluetooth connects directly to the free My Chihiros App, allowing you to set daily schedules, customize individual Red, Green, and Blue spectrum ratios, and configure gradual sunrise/sunset dimming transitions.
3. Are light shades available for the WRGB II SLIM?
Yes! To focus light downward and prevent side-glare when viewing your aquarium, you can install the matching Chihiros SLIM Light Shade with Mirror.

"I adore Chihiros lights and this light does not disappoint! I don't like super harsh gallery lighting and was looking to get a more yellow color in my tank. This light is easy to adjust RGB and timing. The frame of the light is a metal frame you have to screw together but the feeling is so premium!"
"Yes it’s expensive but man does the wide range of features on the app and all the different color controls you get make up for it. The build quality is very sturdy and the looks is so sleek and sexy. The light itself generates very little heat and is super quiet. Comes with ample supplies to set it up and get it going. I’m 100% using Chirhiros moving forward on every tank."
"The light is great, the app not so much. For a $200 light, I would have hoped for an app that’s a bit more intuitive and smooth. Otherwise, the light is awesome, I love that it can be customized. One thing I did not appreciate is that the light cannot be controlled by the app unless you are in Bluetooth range. Disappointing for a $200 light. $10 plugs are doing a better job. If you are out of the house for a month, you’ll just have to trust that the light turns on and off at the right time."
"So far this product has been amazing. Only two weeks in but the settings, which are controlled through the Chihiros app are easy to use and WOW can you make the colors in your tank pop. The green and red plants look so good, all are pearling daily. Biggest wow moment was seeing how my fish look after some customization, this light makes everything look incredible."
"Light works great! It is nice to have a seller in the US that carries this product to avoid the long shipping time if it were to come from China."
"I love how this light can be adjusted via an app and the convenience of it. My only complaint is that there is no shades for the 90, but that's not Buce's fault. It was shipped in a timely manner and got to me in good shape"
"I set this light up almost immediately after it got delivered and I wish I had purchased it before I did because I can already see the difference between this light and my old lights and I only have it set to 22%. The app controller makes it easier and slowly increases and decreases the light to turn on and off when I scheduled it to. My only complaint is that even 22% is so bright and my tank is lower so I need to figure out a shade for it and I can’t seem to find a chihiros shade for the 90 slim but that’s not buce’s fault."
"Utter Perfection for my 20 gallon horizontal tank! Thank you!"
"The light is excellent. High PAR and easy to dial in. Love the light it gives off."
"Chihiros wrgb2 slim—great light showing off colors in fish and plants"
