If your kitchen windowsill is crowded with coriander, basil and mint, moving the pots onto an indoor shelf can give you more room. But that new position may receive less daylight. You now need grow lights for plants that can illuminate the whole arrangement, and the choice comes down to two practical options: the MA120 grow light and the MA200 grow light.
For a compact herb area around 60 × 60 cm, start with the 120W model. For a wider arrangement around 80 × 80 cm, choose the 200W model. The larger light supplies more light overall, making it better suited to the larger footprint. Both offer 0–100% dimming, so either lets you adjust brightness as your arrangement changes.
For buyers in South Africa, the remaining question is whether that extra coverage is worth the additional electricity. Here is how these grow lights for plants compare for a kitchen herb station, a wider growing table and a household running budget. The area examples below refer to leafy growth; crops needing stronger light require a smaller working footprint.
A Compact Herb Station: Choose the MA120 Grow Light
If you are setting up one small herb station, the MA120 grow light is the straightforward choice. Think of coriander, parsley or basil grouped on a square stand, with the leaves occupying roughly 60 × 60 cm. Its 120W input suits this compact arrangement while keeping full-power electricity use below the larger model.
Place the fixture centrally above the group. This gives the plants a shared overhead source instead of relying on light entering from one side of a window. Leave room between the pots for leaves to spread and for watering. A crowded arrangement can shade its own lower leaves even when the lamp above it is powerful enough.
When buying grow lights for plants for this setup, the useful advantage is getting adjustable lighting in a compact board. You can turn the output down when supplementing daylight and increase it when the same position receives less natural light. Both models have this control, so choosing the smaller one still gives you that flexibility.
This is also the sensible option if you expect the station to stay small. A dedicated kitchen herb corner does not need the same equipment as a whole growing table. Put the money towards the area you will illuminate every day: for this compact setup, the lower full-power consumption is a continuing benefit.
A Wider Growing Table: Choose the MA200 Grow Light
If your pots already spread across approximately 80 × 80 cm, choose the MA200 grow light. This could be a wider table in a spare room or a single growing level in a small tent. Its 200W input supports more total light output, giving you more light to distribute across that larger arrangement.
The difference becomes useful when you add another row of herbs or leafy greens beside the first. With grow lights for plants, the outer rows matter as much as the pots directly beneath the centre. Choosing the larger model for the wider footprint is a clearer investment than trying to stretch the smaller light across an increasingly broad table.
There is another reason to consider this model: a compact area of fruiting plants, such as dwarf chillies or cherry tomatoes, can require stronger illumination than a leafy herb station. For this comparison, use approximately 60 × 60 cm as the flowering footprint for the larger model. The extra output can serve either a wider leafy area or a smaller area needing stronger light.
When positioning grow lights for plants, match the shape of the arrangement too. A square footprint and a long, narrow bench use light differently. Keep your pots within the intended working area beneath the board; placing them along a much longer shelf does not make the quoted square coverage extend to both ends.
Compare Output and a Year of Electricity Costs
The extra 80W buys more total light and a larger leafy-growth footprint. This table brings the main differences between these grow lights for plants together. Output figures are approximate; electricity figures use the listed full-power inputs.
| Comparison | MA120 grow light | MA200 grow light |
|---|---|---|
| Full-power input | 120W | 200W |
| Approximate photon output | 315–325 µmol/s | 540–550 µmol/s |
| Approximate efficacy | 2.6–2.7 µmol/J | 2.7 µmol/J |
| Leafy-growth footprint | 60 × 60 cm | 80 × 80 cm |
| Flowering footprint | 50 × 50 cm | 60 × 60 cm |
| Dimming | 0–100% | 0–100% |
| Electricity per day at 18 hours | 2.16 kWh | 3.60 kWh |
| Electricity per year, 365 days | 788.4 kWh | 1,314 kWh |
| Annual cost at an example R3/kWh | R2,365.20 | R3,942.00 |
At that example rate and operating time, the larger fixture costs R1,576.80 more per year to run at full power. That is about R131.40 per month when the annual difference is divided by twelve. The calculation uses 18 hours daily for comparison, not a prescribed schedule for every plant, and R3/kWh is an example rather than a universal South African tariff.
To calculate your own cost, multiply kilowatts by operating hours and your electricity rate. For example, the smaller fixture uses 0.12 kW × 18 hours × 365 days. If your rate differs, replace R3 with the applicable charge on your account. Shorter operating hours or reduced input will lower the total.
Dimming gives both grow lights for plants room to reduce output. A 120W input on the larger model would consume the same electricity as a 120W input on the smaller one. Use actual input power for that comparison: the energy bill follows watts drawn, while the dial is a brightness control.
Which One Should You Put in Your Basket?
Choose the MA120 grow light for a compact herb station around 60 × 60 cm. It gives that smaller arrangement adjustable light with lower full-power electricity consumption. This is a good fit when you want to keep kitchen herbs together on one stand and have no need to illuminate a wider table.
Choose the MA200 grow light for a leafy area around 80 × 80 cm, or a more compact fruiting area around 60 × 60 cm. Here, the additional output has a clear purpose. You are paying for more light across the space or more light concentrated into the smaller fruiting area.
Before ordering grow lights for plants, measure the arrangement with room for mature leaves. A tray of small pots can occupy much less space than those same plants a few weeks later. Choose against the space they will actually fill, and check that the shelf leaves room for the fixture, suspension and ventilation.
Conclusion
For grow lights for plants in South Africa, choose the MA120 grow light for a compact herb setup and the MA200 grow light for a wider leafy area or a smaller fruiting area needing more light. Both offer adjustable output. The larger model adds coverage and output, alongside higher full-power running costs.

Frequently Asked Questions
Do both models have dimming?
Yes. The MA120 grow light and MA200 grow light both offer 0–100% adjustment, allowing you to change brightness without replacing the fixture.
Which model suits an 80 × 80 cm herb area?
Choose the MA200 grow light for that leafy-growth footprint. The smaller model is the choice for a more compact arrangement around 60 × 60 cm.
How much more electricity does the larger model use?
At full input, it uses 0.08 kWh more per hour. Over 18 hours daily and 365 days, the difference is 525.6 kWh, or R1,576.80 at an example R3/kWh.
Can one light illuminate several shelf levels?
A shelf above another can block the light. These grow lights for plants are compared for one growing level; separate levels need lighting positioned to reach each level.
