Grand Master LEDs

Grand Master lights deliver powerful grow lighting built for indoor growers who demand precision, durability, and high output. Known for their multi-channel spectrum control and water-resistant construction, these lights give you full control over your environment from seed to harvest.

For the best PAR consistency we have ever seen on a grow light with added diodes on the edges checkout GML's 4x4 and 5x5 tent grow lights.

Popular Grand Master lighting picks like the Tarantula Borg Evolution V2 and V3 offer intense full-spectrum coverage with Samsung EVO diodes and customizable tuning. Grandmaster LED lights' Tarantula Voyager packs the same top-tier performance with added versatility for various grow spaces. Expect unmatched consistency, rugged build, and proven results in every fixture.

Nice unit

The fan seems well designed and built. The design allowed installation in hard duct work w/o needing a flex section. Not necessary in most installations, but important in mine. Whisper quiet at low speeds. Pleased to discover that the speed control returned to the last selected speed after a power failure.

HLG 350

So far just starting a run, but all is well. I’m playing with the light height and intensity as the run progresses. Easy setup no issues a solid light. I’ve owned dozens of grow lights over decades of growing HGL 350 appears to be on par with the others I’ve owned and still do.

Cheap and dangerous

Dulytek presses are outright dangerous, missing crucial pieces can lead to serious injury. I had missing washers on top of cage springs that launched the nuts and clips like bullets.
