Daystar HID Digital Ballasts.

Every ballast has a Sun System compatible plug. Easy plug n play installation. No wiring to mess with, no chance of harming or destroying the ballast during installation. Fan free design is absolutely silent. Many cheaper ballasts require an internal cooling fan to function. With this fan free design, all necessary cooling is designed into the ballast enclosure itself. Long life, fully guaranteed.
Best warranty in the industry {Full 5 year replacement}
No pro rating. No B.S.

Sun System to Hydrofarm adapter plugs available.

Extended Lamp cord with Sun System style plug is also available in case you have a brand X reflector or are building your own. {Just Ask for it, they are available at no extra cost to you!!}

Digital Ballast Details:
- Auto Sensing design works with either 120vac or 240vac, standardized cord sets available for both voltages.
- Operates both High Pressure Sodium (HPS) and Metal Halide (MH) Bulbs.
- Integrated Sun System compatible Lamp plug. Sun System compatible lamp cord available upon request. Hydrofarm Reflector adapters also available upon request.
- HIGH OUTPUT! Our Daystar HID Digital electronic ballasts are specifically manufactured for the horticultural industry and provide maximum light output!
- LOWER YOUR ELECTRICITY BILL AND SAVE MONEY! More efficient and reduced energy consumption means a lower electricity bill. When compared to standard core and coil magnetic ballasts.
- With a sleek look, the digital ballast is lighter, smaller and more reliable than standard technology "core and coil" ballasts. With its fan-less design it is also COMPLETELY SILENT!
- Shielded components to protect against RF interference with other equipment.
- Intelligent Technology included with the ballast AUTOMATICALLY ADJUSTS TO HIGH PRESSURE SODIUM AND METAL HALIDE BULBS. There is no need for a "switch" or to change systems, simply change from bulbs.
- Operates at a high frequency (20,000Hz) instead of the lowly 60Hz of standard core&coil ballasts. This allows the lamp to operate more efficiently, produce more usable light for plants and last longer. Lamp lumen loss is minimized allowing for a brighter system over time and extending usable lamp life by up to three times it's normal life span!
- LOW HEAT! The digital ballasts run a lot cooler than standard systems improving ballast life.
- BUILT IN COOLING SYSTEM! Passive cooling system requires no noisy fans. Most digital ballasts that fail are due to fan failure and overheating. Eliminating this problematic part raises production cost, but we feel the cost to benefit ratio is well worth it! These ballasts will last you a lifetime!

Dimming Function.
We offer this option on are larger ballasts to provide the ultimate in flexibility. Allows user to select between 100% 75% or 50% output. Starting seedlings but don't want to move the light up? Simply flip the switch to 50%..Now you are producing less light, less heat and using less energy. No more wasted light/heat/energy burning your light at full capacity when its not needed. Also a great feature to control heat during the summer time. Many indoor gardeners cant make it through the summer months because of heat issues in the greenhouse. Simply select a lower output and watch your heat problems disappear!
