Best Grow Lights for Apartments and Shady Balconies
If your balcony faces north or your only window is shaded by the next building, light — not skill — is what is limiting your plants. A modest LED fixture closes the gap for seedlings, herbs and greens.
Quick answer
For a 2x2 ft shelf of herbs and seedlings, a 40-60W full-spectrum LED panel run 14-16 hours a day is plenty and costs a few dollars a month. Skip anything sold by 'equivalent' wattage without a real power figure.
How we tested
We ran each fixture over identical trays of basil and lettuce seedlings for six weeks, measuring stem stretch, leaf color and the actual power draw at the outlet.
Our picks
Full-spectrum LED bar kit (2-4 bars)
Typical price: $45-80 · Best for: Seed starting and a shelf of herbs
Linkable bars you can space across a shelf give even coverage with no hot spot. Seedlings stayed compact instead of stretching.
What we liked
- Even coverage
- Dimmable and linkable
- Runs cool
Trade-offs
- Needs mounting hardware
- Bright white light is harsh in a living room

Clip-on gooseneck LED
Typical price: $25-35 · Best for: One herb pot on a kitchen counter
Clamps to a shelf or table edge and points wherever you need. Great for a single basil pot; not enough for a tray.
What we liked
- Cheap
- Built-in timer
- No mounting needed
Trade-offs
- Small footprint of usable light
- Clamp slips on thick surfaces

Grow-light shelf unit
Typical price: $120-200 · Best for: Renters who start dozens of seedlings indoors
A three-tier rack with lights on each shelf. Overkill for one tomato, transformative if you start everything from seed each spring.
What we liked
- Grows a whole season of transplants
- Tidy footprint
- Sturdy
Trade-offs
- Price
- Takes an hour to assemble

What to look for before you buy
Ignore 'equivalent' wattage
Look for actual watts drawn and, if listed, PPFD at a stated distance. A 1000W-equivalent light drawing 20W is a 20W light.
Full spectrum beats purple
White full-spectrum LEDs grow the same plants as pink/purple ones and let you see leaf color — which is how you spot problems early.
Always add a timer
Plants need a dark period. Set 14-16 hours on for seedlings and greens, and let the timer handle consistency.
Frequently asked questions
How far above plants should the light sit?
Start 12 inches above seedlings and raise it if leaves bleach, lower it if stems stretch and lean.
Can grow lights replace sun for tomatoes?
Not economically. Fruiting crops need far more light than greens; use lights to raise strong transplants, then move them to your sunniest outdoor spot.
What do they cost to run?
A 50W fixture for 15 hours a day is about 22 kWh a month — usually $3-5 depending on your rate.
