Why Choose the WRGB II Pro?

The WRGB II Pro sits just below the VIVID range but delivers serious high-end performance. Compared to standard WRGB II lights, it offers:

• Noticeably higher brightness and penetration
• More precise colour tuning (thanks to the extra white channel)
• Better performance for demanding plants

It’s the perfect choice for aquarists who want flagship-level growth and colour without moving into hanging pendant systems like the VIVID series.

⚠️ Important Notes

• Best used with CO₂ injection and fertilisation
• Too powerful for low-tech tanks without dimming
• Designed for open-top aquariums (not enclosed lids)

Pro Tip 💡

Start at 40–60% intensity and gradually increase as plants adapt—this helps prevent algae and ensures stable growth.
