Lumatek Digital Ballast 250W with four-step control

Product detailed description

Lumatek digital ballast 250W with power control

The Lumatek 250W digital ballast is an electronic ballast for sodium (HPS) and metal halide (MH) lamps up to 250 W with four-step power control. It is suitable for a grower who wants to choose the intensity of one 250W lamp according to the growth stage and switch between energy-saving operation and full power.

Four-step control and Super Lumen

You can switch the power between 150, 175 and 250 W levels depending on the lamp and growth stage you are dealing with. The Super Lumen position (275 W) temporarily increases the power above the rated value when you need to get the maximum from the lamp. Use the control only with dimmable lamps - operate non-dimmable ones at the rated power.

Parameters

Compatibility

Compatible:

• Sodium (HPS) and metal halide (MH) lamps up to 250 W
• Single-ended lamps with an E40 socket

Incompatible:

• CMH (ceramic metal halide) lamps - require their own CMH ballast
• Double-ended (DE) lamps - different socket and holder

Digital vs. electromagnetic ballast

Compared with older electromagnetic types, a digital ballast is lighter (2 kg), quieter and starts up faster. It operates without visible flicker and with low mains distortion (THD below 8 %), which is gentler for the lamp and for the grower than the hard ignition of a magnetic ballast. You can fit a Lumatek 250W MH lamp of the same power to the ballast and install it in the Lumatek Xenon 2 reflector with E40 socket.

Frequently asked questions

How does the four-step control work?
The ballast allows you to switch the power between four levels - 150, 175 and 250 W plus the Super Lumen 275 W position. You choose the power according to the lamp and growth stage. However, use the control only with dimmable lamps; operate non-dimmable ones at the rated power.

What are the ballast parameters?
It is a 250W digital ballast with an input of 265 W, current of 1.2 A and input voltage of 175-275V (50-60 Hz). It measures 200x114x81 mm, weighs 2 kg, has IP23 protection, THD below 8 % and an operating frequency above 80 kHz. It powers HPS and MH lamps with an E40 socket.

Is it suitable for HPS and MH lamps?
Yes, the Lumatek 250W digital ballast is designed for high-pressure sodium (HPS) and metal halide (MH) lamps up to 250 W. MH is used in the growth stage, HPS in the flowering stage; the ballast handles both technologies.
