Spider Farmer SF4000 LED Grow Light vs Medic Grow MINI SUN-2 LED Grow Light

Buy the Spider Farmer SF4000 for a full-size flowering room: 450W, a 5x5 ft bloom footprint and a 6x6 ft veg footprint, with no fan and a solid aluminum heat sink. Buy the Medic Grow MINI SUN-2 for a small tent, a rack or a 2x2 to 3x3 space, where its compact panel, built-in dimmer and timer, and 10 ft cord fit better. The SF4000 is the more proven, widely reviewed fixture with strong owner reports on even coverage and fast growth; the MINI SUN-2 has the higher rating from more owners and a cleaner small-space feature set.

  • Choose the Spider Farmer SF4000 if you are lighting a 5x5 ft flowering area or larger and want one quiet, high-output panel with a long power cord and simple hanging.
  • Choose the Medic Grow MINI SUN-2 if you grow in a 2x2 to 3x3 tent or on a rack and want a compact panel with a built-in dimmer and timer.

Questions and answers

Which is better for a 4x4 tent?
The SF4000. Its 5x5 ft flower footprint covers a 4x4 tent with margin, while the 150W MINI SUN-2 covers only about 2x2 ft in flower.
Which is better for a 2x2 tent?
The MINI SUN-2. It is built for that size, and its built-in dimmer and timer are handy in a small space. The SF4000 is far more light than a 2x2 tent needs.
Which lasts longer?
Both are fanless with aluminum heat sinks, so there is little to wear out. The SF4000 lists a 5,000-hour lifespan; the MINI SUN-2 does not publish one, so judge it by its driver and warranty terms.
Is the SF4000 worth stepping up to from the MINI SUN-2?
Yes if you are moving to a 4x4 or 5x5 flowering space. It gives roughly three times the wattage and a much larger footprint. Stay with the MINI SUN-2 if your space is small.
Can I control either one from a controller?
Yes. The SF4000 takes any universal 0-10V controller, and the MINI SUN-2 works with the GLC-1 controller as well as its own built-in dimmer.
Do either make noise?
No. Both are fanless and rely on passive aluminum heat sinks, so neither adds fan noise to the grow room.
