8 Best Grow Lights for Greenhouse Cabinets in 2026
Eight short grow light strips for glass greenhouse cabinets such as IKEA Milsbo and Rudsta, compared on length, mounting on glass, timers, and cord routing.
By Ethan Cole
Updated November 2, 2026
A glass display cabinet turned into an indoor greenhouse (IKEA cabinets such as Milsbo and Rudsta are popular for this) holds humidity for tropical plants, but the shelves sit far from any window. Short, low-profile strips mounted under each shelf are the usual fix.
This guide compares eight lights that fit inside a cabinet: short bars and strips with adhesive, screw, or magnetic mounting, built-in timers, and cords that can run out through a door gap or the back. Cabinet sizes vary, so measure your shelves before you buy. For open shelves see grow lights for shelves.
Safety note: a closed cabinet holds heat and humidity. Keep power adapters, timers, and plugs outside the cabinet where possible, route cords so they are not pinched by the door, and leave some ventilation. We describe what each maker lists; we do not promise growth results.

Top 3 Grow Lights for Greenhouse Cabinets Reviewed
#1 Mosthink Under Cabinet Grow Light Strip (2 Bars): Best Overall
Why We Picked It
Mosthink’s under-shelf strip has the largest rating base of any cabinet light we compared: 4.3 stars on about 7,700 ratings. It is sold for exactly this use, with two 13.75-inch bars, 96 LEDs, and 15 watts in total.
The controller sets a daily timer (the listing says it turns off after 2, 4, or 8 hours and repeats the next day) and 4 brightness levels. The 78-inch cord is long enough to reach an outlet outside most cabinets.
Key Specifications
- Bars: 2 x 13.75 in
- Power: 15W; 96 LEDs
- Timer: 2/4/8H off, repeats daily (listed)
- Dimming: 4 levels
- Cord: 78 in
- Mounting: screws, double-sided tape
| Pros | Cons |
|---|---|
|
|
Things to Consider
The 2, 4, and 8-hour options are short for a full day of light. If you want longer days, leave the timer off and use an outlet timer on the plug.
Best For
One or two cabinet shelves of tropical houseplants.
Skip It If
Skip it if you want long timer settings built in; Wiaxulay and LPMZMBL go to 16 and 18 hours.

#2 Barrina T5 1 ft Magnetic Grow Lights (2 Pack): Steel Shelves
Why We Picked It
If your cabinet shelves or frame are steel, these 1-foot Barrina bars attach with built-in magnets and move easily as you rearrange plants. For glass or wood, Barrina includes magnetic bars with double-sided tape. The T5 family scores 4.6 stars on more than 7,000 ratings, pooled.
Each bar is 5 watts in 5000K white with its own switch, and the line links up to 16 bars if you light every shelf.
Key Specifications
- Length: 1 ft (12.6 in listed)
- Power: 5W per bar
- Color: 5000K white
- Mounting: magnets, magnetic bars with tape, clips, ties
- Control: switch on each bar
- Linking: up to 16
| Pros | Cons |
|---|---|
|
|
Things to Consider
Check that your cabinet’s metal holds a magnet before relying on it; some frames are aluminum.
Best For
Cabinets with steel shelves, or anyone who rearranges often.
Skip It If
Skip it if you want a timer in the light.

#3 Wiaxulay 8 in Grow Light Strip (4 Bars, 2 Pack): Narrow Shelves
Why We Picked It
Wiaxulay’s 8-inch bars are the shortest here, for narrow or shallow shelves. Each kit has four bars, and this listing includes two kits. It scores 4.6 stars on about 240 ratings.
The controller has a 6, 12, or 16-hour timer, 5 brightness levels, and 3 modes; the listing describes a 5000K seedling mode, a warm bloom mode, and a full spectrum mode. Adhesive strips, magnetic clips, and cable ties are included.
Key Specifications
- Bars: 4 x 8 in per kit, 2 kits
- Color: 5000K, warm, and combined modes
- Timer: 6/12/16H
- Dimming: 5 levels
- Mounting: adhesive strips, magnetic clips, ties
- Power: not listed
| Pros | Cons |
|---|---|
|
|
Things to Consider
Short bars need to sit close to the plants they light. Place them over the pots, not just along the shelf edge.
Best For
Small cabinets and shelves under 12 inches wide.
Skip It If
Skip it if your shelves are wide; 14 to 16-inch bars cover more.
Check current pricing and availability for the Wiaxulay 8 in Grow Light Strip (4 Bars, 2 Pack).
How to Choose Grow Lights for a Greenhouse Cabinet
Measure Each Shelf
Measure width and depth inside the cabinet. Bars here run from 8 to 16 inches; pick the length that spans the shelf without hitting the side walls.
Mounting on Glass
Glass shelves need adhesive or clamp-style mounting; screws only work on wood or metal. Adhesive can let go in high humidity, so press firmly and keep the surface clean before you stick.
Cord Routing
Plan where cords leave the cabinet. Thin USB cords pass through door gaps more easily; keep adapters and timers outside.
Light Color Behind Glass
A display cabinet is meant to be looked at. White light shows plants best; red and blue strips turn the cabinet pink.
How We Evaluate Grow Lights for Greenhouse Cabinets
We did not grow plants under these lights. We compared manufacturer specifications and Amazon listing details, and ranked products by the WikiHomeLED Score, which adjusts the Amazon star rating for the number of ratings (ratings checked November 2, 2026). To qualify, a product had to be a short LED grow light bar or strip suited to mounting inside a cabinet, with at least 20 ratings and a rating of 4.1 stars or higher, one listing per product family. PPF, PPFD, lumen, and wattage figures are as published by each seller and are not our measurements. The full method is on our How We Review page. IKEA is named only to describe how these lights are used; we have no relationship with IKEA, and cabinet dimensions vary by model.
Frequently Asked Questions
What grow lights work in an IKEA greenhouse cabinet?
Short under-shelf strips and bars, usually 8 to 16 inches, with adhesive or magnetic mounting and a timer. Measure your shelves first.
Do grow lights make a cabinet too hot?
LED strips at these wattages produce little heat, but a closed cabinet holds it. Leave some ventilation and keep adapters outside.
How do I run the cords out of a closed cabinet?
Through the door gap or a small opening at the back. Keep cords from being pinched by the door and keep plugs outside.
Can I mount grow lights on glass shelves?
Yes, with adhesive tape or adhesive magnetic bars. Clean the glass first, and check the bond after a few days in humid air.
Final Verdict
The Mosthink under-cabinet strip is our pick for most cabinet greenhouses: made for under-shelf use, the largest rating base, and a long cord. Choose Barrina’s magnetic 1 ft bars for steel shelves, or Wiaxulay’s 8-inch bars for narrow ones. If you want longer timer settings, LPMZMBL and Wiaxulay run up to 18 and 16 hours.
