PHANTOM Cultivar GL250 LED, 250W Grow Light (10' 110-120V Plug)

Compact 250W LED with Onboard Dimmer and Spectrum Switch

Small tents and single-shelf grow spaces often can't justify a full external controller just to dim one or two lights, but growers still want that level of control. The PHANTOM Cultivar GL250 is a compact, IP65-rated 250W LED fixture built around an aluminum unibody heatsink, with its dimming and spectrum controls built onto the fixture itself.

A 10-foot cord and standard 110-120V plug make it ready to run in a typical home outlet without additional wiring.

Key Features & Benefits

• 250W Rated Input Power — delivers 641 µmol/s photon flux (PBAR 280-800nm) and 625 µmol/s (PAR 400-700nm).
• 2.56 µmol/J Efficacy — reflects the fixture's output per watt of input power.
• Aluminum Unibody Heatsink — supports longer diode life and less output degradation over time.
• MAD Dimmer Knob — controls up to four daisy-chained GL250 fixtures via included RJ12 cords, dimming from 40-100% output.
• Two-Step Spectrum Switch — toggles between a full-spectrum FLOWER mode and a red-reduced VEG mode.

Who Should Use the GL250

The GL250 suits growers who want a single, compact fixture with onboard dimming and spectrum control, without needing to add a separate external controller. Up to four fixtures can still be linked to one dimmer knob for small multi-fixture setups.

About PHANTOM

PHANTOM is an established horticultural lighting brand spanning traditional ballast-and-reflector HID systems alongside newer LED lines, including the Multi Phase (MP) series that the Cultivar GL250 builds on. The GL250's onboard MAD dimmer and Two-Step Spectrum switch carry that same low-profile, high-efficiency design approach into a compact single-fixture format.

Frequently Asked Questions

What is the rated efficacy of the GL250?

2.56 µmol/J, with 250W of rated input power. That efficacy reflects how much usable light the fixture produces per watt of electricity consumed.

How many fixtures can I control with one dimmer?

Up to four GL250 fixtures can be daisy-chained from a single MAD dimmer knob using the included RJ12 cords. This lets a small multi-fixture setup share one dimming control without a separate external controller.

What does the spectrum switch do?

It toggles between a full-spectrum FLOWER mode and a red-reduced VEG mode for vegetative growth. Growers can switch modes directly on the fixture as plants move between growth stages.

What voltage and cord does it use?

Standard U.S. 120Vac input with a 10-foot cord and a standard 110-120V plug. No additional wiring or electrician visit is required for a typical home outlet.

Is it eligible for utility rebates?

It is DLC Hort QPL listed and eligible in regions that offer such rebates. Reach out to your utility provider directly to confirm current rebate program details.
