All Lumii’s famous, real-world grow experience is packed into this dimmable, output-optimising 600w electronic ballast, helping you regularly achieve superb yields. The Lumii Black 600w Electronic Ballast features micro-processor control to elevate the performance of your lamps and the necessary adjustability to ensure your crops are always getting the just right amount of light.

That adjustability comes in the shape of 250w, 400w, and 600w dimmer settings, the first two of which are perfect for early veg phases. You can also turn it up to 11 in the flowering phase using the 660w super-boost setting. Whatever setting you’re on you can rest assured that the Black 600w Electronic is pouring it on in terms of usable light whilst precisely walking the line between performance and efficiency. A relatively light 3 kg weight, silent running, cool operating temps, and a ready-fitted IEC cable all make the ballast an easy fit with any growing space.

• Micro-processor control elevates lamp performance
• Adjust to 250w, 400w, 600w or 660w output to match every stage in growth
• Low watt settings for early veg stage, higher watt for veg stage proper and flowering
• Lightweight, silent running, and cool operation for grow room practicality
