The ballast can sense which type of HPS lamp is being driven and will adjust accordingly. If a standard format HPS lamp is used the performance will be the same as using a standard Lumatek ballast. Using the 400 volt lamp and ballast together will see the higher performance.
The Big benefits;
- 5% more plant light energy than the standard ballast.
- Completely compatible with all your usual reflectors.
- Plugs into your normal wall connection
- Soft start technology
- Random start technology
Under no circumstances use a 400 volt lamp in any other ballast.
