Up to 70% savings can be realised by replacing inefficient HID lighting with High Bay energy efficient flourescent lighting.
Now you can replace your old out-dated fixtures one-for-one with the
Conservelec High Bay Lights and improve your light levels with half the energy.
Six lamp T8 and four or six lamp T5 fixtures allow high-bay fluorescent lighting to be used in many different applications at a variety of heights.
Customise the High Bay Lighting using the wide variety of options and accessories to perfectly fit your specific needs.
Quick & easy installation, superior optical performance and many years of trouble free operation are a few of the many benefits of the High Bay Industrial light.

One lux equals 1 lumen per square metre.
A luminous flux of 100 lumens concentrated into an area of one square metre (I metre x 1 metre) lights up that square metre with an illuminance of 100 lux. The same quantity of light spread over an area of four square metres (2 metres x 2 metres) will result in an illuminance of 25 lux.
Many other factors (such as luminous efficacy, colour rendering (or CRI index), and pupil conversion factor, etc) must be taken into account before attempting to compare fixtures based on lumens output alone.
| Colour rendering index of HID and fluorescent lamps (CRI of 100 is best) | |
|---|---|
| 350 W pulse start HID; 400 W HID | 60 - 70 |
| T8 and T5 fluorescent tubes | 75 - 98 |

Correction factors applied to conventional values of lumens per watt (L/W) yield a value for pupil lumens per watt, which is a measure of how effectively the eye sees the light that is emitted.
| LIGHT SOURCE | Conventional L/W | Correction Factor | Pupil L/W |
|---|---|---|---|
| HID | 40 | 0.86 | 34 |
| 4,100K T8 fluorescent | 90 | 1.62 | 145 |
| 5,000 T5 fluorescent | 104 | 1.83 | 190 |
