Most indoor plants are not short of water or fertilizer. They are short of light. A north-facing window in winter can deliver a fraction of what a fiddle leaf fig, a basil plant or a tray of tomato seedlings needs, and the result is the same every time: leggy stems, small pale leaves and plants that slowly give up.
A grow light fixes that. The trick is buying the right type for your space, because a clip-on lamp, a shelf strip and a hanging panel solve completely different problems. Below are our five picks, then a short guide to choosing.
Quick picks
| Best for | Grow light | Type |
|---|---|---|
| Plant shelves and seedlings | Barrina T5 LED strips | Linkable strips |
| One big houseplant | SANSI 36W grow light bulb | Screw-in bulb |
| Desks and small budgets | GooingTop clip-on grow light | Clip lamp with timer |
| Living rooms (looks good) | Soltech Aspect pendant | Designer pendant |
| Herbs, veg and fruiting plants | Spider Farmer SF1000 | Full-spectrum panel |
1. Barrina T5 LED strips: best for shelves and seedlings
If you have a bookshelf, a wire rack or a seed-starting setup, Barrina’s T5-style strips are the most popular choice among indoor growers for good reason. Each bar mounts under a shelf, the bars link together so several run from one plug, and the white 5000K light looks normal in a room rather than purple.
- Good: even light across a whole shelf, low power draw, cheap per plant, easy to install.
- Not so good: no built-in timer on most packs (add a plug-in timer), and the light is too weak for fruiting tomatoes or peppers.
- Buy it if: you grow many small plants, succulents, herbs or seedlings on shelves.
2. SANSI 36W grow light bulb: best for one large plant
The simplest grow light of all is a bulb. SANSI’s 36W full-spectrum bulb screws into a standard E26 lamp socket, so you can put it in a floor lamp, a clamp light or a pendant cord over a monstera, fiddle leaf fig or bird of paradise. It is one of the most recommended bulbs in houseplant communities because it is bright enough to make a real difference to a single large plant.
- Good: works in lamps you already own, warm-white light that fits a living room, strong output for one plant.
- Not so good: covers a small area, so it is not efficient for many plants; runs warm, so keep it a sensible distance from leaves.
- Buy it if: you have one or two statement plants in a dim corner.
3. GooingTop clip-on grow light: best budget pick
A gooseneck clip light is the cheapest way to start. GooingTop’s model clips to a desk or shelf edge, has flexible arms you can aim at each plant, and includes a timer and brightness levels so you can set it and forget it.
- Good: low price, built-in timer, easy to move around.
- Not so good: lower output than a bulb or panel, and the clip and arms feel lightweight.
- Buy it if: you have a few small plants on a desk or windowsill and want to test whether extra light helps.
4. Soltech Aspect pendant: best-looking grow light
Most grow lights look like equipment. Soltech’s Aspect looks like a designer pendant lamp, which is why it shows up in so many styled living rooms and kitchens. It hangs above a plant or a group of plants and gives off warm, natural-looking light.
- Good: attractive enough to hang anywhere, natural light colour, solid build.
- Not so good: expensive for the area it covers.
- Buy it if: the light will be on show and appearance matters as much as output.
5. Spider Farmer SF1000: best for herbs, veg and fruiting plants
Tomatoes, peppers and strawberries need far more light than houseplants. A full-spectrum LED panel like the Spider Farmer SF1000 (around 100W) is built for that job: it covers a small grow area evenly and has a dimmer so you can turn it down for seedlings and up for flowering plants.
- Good: real growing power, dimmable, efficient for its output.
- Not so good: looks like grow equipment and is overkill for ordinary houseplants.
- Buy it if: you want to grow food indoors, in a corner, a cupboard or a small grow tent.
How to choose a grow light
1. Match the type to your space
- One plant: a screw-in bulb in a lamp or clamp light.
- A few small plants on a desk: a clip-on gooseneck light.
- Shelves or seed trays: linkable LED strips.
- Growing food: a full-spectrum LED panel.
2. Ignore “equivalent watts”
Claims like “2000W equivalent” are marketing. Look at the actual power draw in watts, and if the seller publishes it, the PPFD (how much usable light reaches the plant at a given distance). Higher real wattage and higher PPFD mean more growing power.
3. Choose white light for living spaces
Purple “blurple” lights grow plants fine but make a room look strange. Full-spectrum white LEDs (roughly 3000K to 6500K) grow plants just as well for most home uses and let you see your plants’ real colours.
4. Get a timer
Plants do best with a steady routine. Most houseplants and herbs are happy with 12 to 16 hours of light a day. If your light has no timer built in, a cheap plug-in timer does the job.
5. Get the distance right
Too far and the light does little; too close and leaves can bleach. As a starting point, keep strips and clip lights around 6 to 12 inches above plants and bulbs or panels further away, then follow the maker’s guidance. If leaves stretch toward the light, move it closer. If they fade or crisp, move it back.
Grow light FAQs
Can a normal LED bulb work as a grow light?
A bright household LED helps low-light plants a little, but dedicated grow bulbs put out much more usable light for the same socket. For anything beyond a pothos or snake plant, a proper grow light is worth it.
How many hours should a grow light be on?
12 to 16 hours a day suits most houseplants, herbs and seedlings. Plants also need a dark period, so do not leave lights on 24/7.
Do grow lights use a lot of electricity?
Not much. A 36W bulb running 14 hours a day uses about 0.5 kWh a day. Even a 100W panel on the same schedule uses roughly 1.4 kWh a day.
Our verdict
For most people, the Barrina T5 strips are the best all-round grow light because they cover the most plants for the money. If you only have one or two big plants, the SANSI 36W bulb is the easiest upgrade you can make.
