Product Questions

1:Can I dim double-ended bulbs?

2:What's the percentage I can dim by?
Question by: David on Mar 3, 2023, 10:14 AM
Thank you for reaching out to BRS. This ballast is not dimmable, it will only power the lamp on or off.
Let me know if you have any other questions, and have a great day.

How long are radiums lasting when you use the dimming feature?
Question by: Mark on Oct 29, 2017, 8:21 AM
In most cases, people are changing out their Radium bulbs after 8 months to a year with most dimmable and standard ballasts. There are many variables with dimmable lamps since the duration of the ramp, and time on per day can drastically affect the lifespan of the bulb. We suggest taking some PAR readings when the lamp is new and monitoring the light degradation over time to know when to change it.

Will these run Radium bulbs?
Question by: Jason Weage on May 20, 2017, 10:22 AM
They will indeed! We actually have one of these ballasts running a 250w Radium in-house right now and it looks fantastic! With the dimming/adjustability aspect, I think it's possible to even tune the output for the best balance of color and intensity now!

Happy reefing!
