If you are fitting out a grow tent or indoor growing room, you may already have two lamps in your basket: a 720W model at R4,999 and an 800W model at R6,500. You still need to buy ventilation and finish the installation. Is spending another R1,501 on the lamp the best use of that money?
Our GLOC720 720W Grow Light is the lower-cost starting point for this purchase. The OC800W-S 800W Grow Light offers more total light output and a folding eight-bar frame. Both provide full-spectrum lighting and adjustable output. Comparing these LED grow lights means deciding which difference will help in your own setup.
For buyers in South Africa, this guide follows the order in which that decision becomes useful: where the fixture will go, how the purchase and electricity costs compare, and which model to put in the order. You can then choose LED grow lights with a clear reason for the price difference.
Illustrative layout.
Start with the Space Where the Lamp Will Hang
Picture the growing area after the equipment is installed. The lamp hangs over the plants, ventilation occupies some of the space above, and you still need access for watering and removing pots. These are broad fixtures: GLOC720 measures 105 × 108.5 × 4.2 cm; OC800W-S measures 111.5 × 111 × 9.3 cm.
If you have a 150 × 150 cm tent, consider OC800W-S first for that layout: its product page gives a general coverage range of 2–2.5 m², and the tent floor is 2.25 m². Use that as a starting point; light distribution still depends on the installation. GLOC720's body also fits within those floor dimensions, but its page does not provide the same coverage figure.
When comparing LED grow lights for a permanent room, GLOC720's built-in driver gives you one assembly to position above the planting area. There is no separate driver box to find a mounting position for. If you regularly dismantle the setup or carry the lamp through doorways, OC800W-S's folding frame gives you a practical handling benefit.
Decide which arrangement describes your purchase. GLOC720 suits the buyer prioritising a straightforward permanent installation and lower spending. OC800W-S deserves the extra consideration when folding will be used. For either of these LED grow lights, plan around the complete operating dimensions, with space for ventilation and plant care.
Compare the Purchase Difference with the Electricity Difference
Keep the two costs separate. OC800W-S costs R1,501 more to buy. Its additional 80W also uses more energy when both fixtures run at full power for the same number of hours. Your operating hours determine how much that second difference matters.
Illustrative budget.
The table uses 2,000 full-power hours and an example electricity rate of R3/kWh. Those are common comparison assumptions for these LED grow lights, rather than a crop schedule or your actual tariff.
| Cost or output | GLOC720 | OC800W-S |
|---|---|---|
| Lamp purchase | R4,999 | R6,500 |
| Power | 720W | 800W |
| Total photon output | 1,872 µmol/s | 2,080 µmol/s |
| Efficacy | 2.6 µmol/J | 2.6 µmol/J |
| Electricity used over 2,000 hours | 1,440 kWh | 1,600 kWh |
| Electricity at example R3/kWh | R4,320 | R4,800 |
| Lamp plus example electricity | R9,319 | R11,300 |
In this example, the electricity difference is R480 and the combined difference is R1,981. For a first installation, ask whether you would rather buy the higher-output folding fixture or keep that money available for the remaining equipment. A lower lamp price matters most when it helps you complete a setup you can actually use.
For shorter use, the electricity difference shrinks. At 500 full-power hours and the same example rate, it is R120. The R1,501 purchase difference remains, so occasional use makes the upfront price relatively more important.
Add any separately purchased support, ventilation and controls to both budgets. The table compares LED grow lights and their example electricity use; it is not the price of a complete growing room. Dimming can change consumption, but a dial position alone does not tell you the actual input power.
Choose Around the Purchase You Are Making
You now have two concrete benefits to weigh: GLOC720 leaves more of the budget available, while OC800W-S adds output and folding convenience. These buying situations help you decide:
- Your first permanent installation: choose GLOC720 when completing the whole equipment order is the priority. Keep the R1,501 purchase saving available for the other items. You retain full-spectrum lighting and dimming.
- A setup you regularly move or store: choose OC800W-S when its folding frame will make those changes easier. It still needs the full unfolded space while operating, but handling is a benefit you can use repeatedly.
- An order prioritising the highest output of these two models: choose OC800W-S for its additional 208 µmol/s. Budget for the extra purchase cost and energy use alongside that output increase.
- Replacing a lamp that already works well: keep the existing fixture unless the additional output or folding solves a specific problem. A larger number on the product name is not a reason to start the purchase again.
For greenhouse use, consider how much daylight the plants already receive. These LED grow lights would be supplementing that light, so the full indoor comparison cannot tell you what the greenhouse needs. Choose the equipment around the actual supplementary-light requirement.
Conclusion
For a first permanent setup in South Africa, GLOC720 is the price-conscious choice between these LED grow lights: full-spectrum output, dimming and a lower initial bill. OC800W-S earns its place when you want the higher total output or will use the folding frame.
Browse our LED grow lights with that choice in mind. Complete the equipment budget before ordering, and pay the premium when its specific benefit matters to your installation.
Frequently Asked Questions
Can dimming make an 800W lamp use less electricity than a 720W lamp?
It can if its actual input power is lower over the same hours. Both LED grow lights have adjustable output. Compare measured consumption at the settings used, rather than assuming a particular dial percentage gives an exact wattage.
Does folding reduce the space needed while the light is operating?
No. Folding helps with carrying and storage. OC800W-S needs its unfolded operating space, including clearance for hanging and airflow.
Do the lamp packages include a complete support frame or controller?
The product pages list power cables, rope hangers, steel hanging wires and connection cables. Those lists do not include a complete freestanding support frame or an external controller. Include any required separate equipment in the order budget.
Can I calculate the number of plants from 720W or 800W?
Wattage alone cannot give a reliable plant count. Plant size, spacing and light distribution matter. Fixture dimensions describe the equipment, and total photon output does not establish the light received at every planting position.
