The perfect ballast for Reef Brite Metal Halide Pendants and many others.
Compatible with all 400W metal halide lamps.
- Dimmable 1-10V
- Connects directly to Reef Brite Reflectors
Digital ballasts are easily the best ballasts you can find for metal halide lamps. The digital processor inside of the ballast will automatically detect the type of bulb, and the start mode that will allow it to fire properly. Once the lamp is fired and running the ballast will also set the proper power output to the lamp for the best color and intensity.
Reef Brite Digital Ballasts are fully dimmable through any 1-10V controller like an Apex. The ballasts use true incremental dimming instead of variable wattage like other leading ballasts. Incremental dimming allows you to ramp up the lamp up and down manually through your controller. We do recommend running the lamp for 1 week before using the dimming feature, allowing the bulb to "burn-in" giving the lamp a much longer lifespan.

Will this ballast work only with 400W bulbs, or is it smart enough to detect 250W bulbs and fire them up properly too?
I was not able to find any mention of this bulb supporting 250 watt bulbs so I would have to say that it will not detect the different bulb wattage. If you need an adjustable ballast check out the Luxcore which will handle both 250 and 400 watt bulbs.
How large, and especially, how heavy is this ballast?
The manufacturer lists the measurements of the ballast at 15” x 8.75” x 4.5” and our system has the weight listed at 10lbs.
When dimming a metal halide bulb using this ballast, how much is the color of the light affected?
The color of the bulb is likely to vary a bit as it is dimmed but that is going to depend entirely on the bulb. A Radium for instance will often burn whiter at higher wattage and bluer and lower wattage.
Hi. Will the Reef Brite digital ballast work with a Cayman Sun reflector (400w)? Also, it says BRS recommends the luxcore ballasts for Cayman Sun reflectors. Why is that?
The Reef Brite ballast will work with the Cayman sun reflector but will require a bit of rewiring since the plugs don't match up. We recommend the Luxcore because of its flexibility and because most Hamilton reflectors plug directly into it.
