Below: the fixture question, the four linear high bays in the listings ranked by stated specs, how lumens and watts compare, dimming and sensors, and the warranties as stated.

Linear vs high bay LED shop light: the fixture question

Linear high bays are long rectangular fixtures that hang in rows; round high bays (UFO style) are a separate format not shown in these listings. The four listings here are all linear: 2FT to 4FT long, 200W to 300W, 28000 to 45000 lumens, all at 5000K daylight. The listings describe the linear array as forming a continuous light band that eliminates the brightness gradients of point sources, with even distribution and fewer hot spots. The YXL claims 43% better center uniformity from its directed distribution, and the Lightdot claims twice the illumination area of UFO lights from its milky cover; both are the makers’ claims.

The four linear high bays in the listings, ranked

Ranked by stated specs, best first. The G GJIA leads: 300W, 45000 lumens at 5000K, up to 150LM/W, UL Listed with ETL in the spec table, selectable wattage, 0-10V dimming with PIR sensor compatibility, a ventilated aluminum housing at 35.43 x 9.84 x 1.75 in and 9 lbs, backed by a 5-year warranty. It is the most specified of the four.

Second is the YXL: 300W, 45000 lumens at 5000K, efficacy of 150 lm/W or better, UL listed, 0-10V dimming with optional PIR motion sensor, military-grade aluminum cooling, glass lenses, 36.41 x 11.02 x 8.66 in, a 5-year warranty and a 30-day return policy. Third is the Lightdot 8-pack: 200W, 28000 lumens at 5000K, up to 140LM/W, ETL Listed, CRI 90, 2FT fixtures at 24 x 11 x 3 in and 5 lbs each, with a 5-year warranty. Fourth is the hykolity 2-pack: 250W, 33750 lumens at 5000K, 135LM/W, 0-10V dimmable, ETL, 4FT at 45.67 x 11.81 x 1.73 in and 14.3 lbs; its bullets claim a 5-year warranty while its spec table says 3-year, so the warranty term is unclear.

Lumens, watts and efficacy

Lumens run 28000 to 45000 across the four listings: 28000 on the 200W Lightdot, 33750 on the 250W hykolity, 45000 on both 300W listings. Efficacy runs 135 to 150 lumens per watt as stated: 135LM/W on the hykolity, up to 140LM/W on the Lightdot, up to 150LM/W on the G GJIA and 150 lm/W or better on the YXL. All four are 5000K daylight. The listings claim energy savings of 80 to 85% against metal halide, stated as the makers’ claims. None of the listings states how many fixtures a given room needs, so compare on the per-fixture figures. Color temperature is 5000K daylight on all four, with CRI 80 or better stated on the hykolity and CRI 90 on the Lightdot.

Dimming and sensors

Three listings state 0-10V dimming: the hykolity (0 to 100%, dimmer not included), the G GJIA (10 to 100% with PIR sensor compatibility) and the YXL (with optional PIR motion sensor). The Lightdot states no dimming. The YXL motion sensor detects movement at up to 50 feet with a 30-foot coverage diameter per the listing, dimming to 30% when no motion is detected. A dimmer must be purchased separately where stated; the listings do not include one.

Hanging and mounting

The listings describe hanging, not hardwiring steps. The hykolity hangs by included chains and V-hooks; the Lightdot hangs by a 1.2mm steel cable with dual hooks or mounts flush with screws and wall plugs; the G GJIA includes an adjustable suspension chain; the YXL lists ceiling mount installation. All four are indoor listings. For hardwired installs, use a licensed electrician.

Warranty and safety listings

The Lightdot, G GJIA and YXL each state a 5-year warranty. The hykolity bullets claim 5 years while its spec table says 3-year; the bullets win per the listing hierarchy, but the conflict is worth noting. For safety listings, the hykolity and Lightdot are ETL listed, the G GJIA is UL Listed with ETL in its spec table, and the YXL is UL listed. For hardwired installs, use a licensed electrician; the listings describe hanging with chains, cables or mounts, not wiring steps.

Do these need a dimmer?

Three list 0-10V dimming: hykolity, G GJIA and YXL. The hykolity and YXL listings state the dimmer must be purchased separately. The Lightdot states no dimming.

What warranty do they carry?

The Lightdot, G GJIA and YXL each state a 5-year warranty. The hykolity bullets claim 5 years while its spec table says 3-year; the bullets take precedence per the listing hierarchy, but the conflict is worth noting. The YXL also states a 30-day return policy.
