Top Features
- BETTER LIGHT PENETRATION: The 2026 New SF4000 features upgraded high-performance Bridgelux LEDs, delivering strong, even light output with excellent canopy penetration. With an increased diode count and optimized layout, light efficacy, PPF output, and uniformity remain consistent with the previous Samsung-based version—helping you achieve reliable yields.
- HIGH EFFICIENCY & PREMIUM U.S. BRAND DIODES: The SF Series is engineering-upgraded with high-performance Bridgelux diodes, increasing diode count so each LED operates under lower load for reduced stress, improved thermal stability, and extended lifespan. Veg footprint is 5 x 5 ft, Flowering footprint is 4 x 4 ft.
- DIMMING DESIGN: The dimming knob can adjust the light intensity at liberty. Multi-light Connection with unified dimming is especially beneficial for large areas of indoor growing and commercial planting.
- IDEAL FOR ALL GROWTH STAGES: With excellent full spectrum light – white, blue, red and IR (3000K, 5000K, 660nm and IR 760nm), the 3000K diodes provide more reddish light and the 5000K diodes provide more blueish light. The 660nm red and IR light is especially useful during blooming stages as it speeds up flowering time and boosts yields. Turn your seeds into your own supply!
- WELL-MADE & SOLID CONSTRUCTION: The SF4000 produces no fan noise, comes equipped with a branded high safety performance driver and good quality waterproofing. The updated aluminum material is thick and sturdy and doesn’t put out a tremendous amount of heat while also providing high-quality protective covers for cables and arriving in user-friendly packaging.

Makes everything look so much clean
got these mostly to deal with all the random cords around the house, and they made a bigger difference than I expected.
They’re simple, but they actually do what they’re supposed to. Once everything is tucked inside, it instantly makes the area look way more organized and less cluttered. I’ve been using them for things like power strips and extra cords, and they hide everything really well.
They’re lightweight but still feel sturdy enough, and the lids stay on without being annoying to open.
Pros:
Really helps clean up the look of messy cords
Easy to use, no setup needed
Simple design that blends in
Cons:
Not huge, so larger power strips can be a tight fit
Plastic isn’t super thick
Overall I’d definitely recommend these if you’re trying to make a space look cleaner without doing anything complicated.

Great Space Saver!
I purchased these for our family room charging hub and honestly wish I had known about them sooner. They are sturdy and very kid proof (at least for my kids). I love the push and lift design so little hands can’t just lift it open and they hold a lot yet blend in.

Handy boxes hides wire clutter.
Does what it is meant for. A bit hard to open once the top is fitted.

Clean, secure cable management
These are good cable boxes that close securely. They hide cables very well and look clean and blend into the home well.
