Alternatives for standard incandescent globes
Although traditional incandescent globes were phased out back in 2010, some businesses still use them. Given that they use up to 85% more power than their energy efficient alternatives, it makes sense to replace them sooner rather than later.
Incandescent globes only last for 750–1,000 hours, but an LED globe can last for up to 50,000 hours. The savings that you’ll make by switching to ‘Compact Fluorescent Lamp’ (CFL) or LED globes are listed below.
| Alternative lighting |
Estimated lifespan of alternative lighting | Estimated running cost reduction[1] |
| Halogen GLS | 2,000 hours | up to 30% |
| CFL | 8,000–15,000 hours | up to 80% |
| LED | 25,000–50,000 hours | up to 80% |
If you want to check out and compare the full range of LED lamps and CFLs, the best place to do so is at a specialist lighting shop.
Unlike the energy efficient lamps of yesteryear, they now come in a wide range of sizes and they give out a wonderful quality light.
‘Watt’ to look for when replacing incandescent lights
When it comes to replacing incandescent globes, it’s important to know what lighting will give you the same amount of brightness.
The brightness of a light is measured in ‘lumens’. This table shows you what to look out for when replacing incandescent globes with CFL and LED lighting.
| Ordinary Incandescent Globe | CFL Lamps | LED | Lumens (Brightness) |
| 25W | 7W | 4W | 250 |
| 40W | 9W | 6W | 400 |
| 60W | 11W | 8W | 600 |
| 75W | 15W | 11W | 800 |
| 100W | 20W | 14W | 1,050 |
| 120W | 23W | 18W | 1,300 |
When your CFL globes expire, replacing them with LED will reduce your energy use.
