The table below shows the Light Reflectance Values (LRV) of anti-slip and photoluminescent material used in Ecoglo step edge products.
Light Reflectance Values
| Material | Reflectance Value |
| Black Anti-slip | 5% |
| Grey Anti-slip | 19% |
| Yellow Anti-slip | 45% |
| Photoluminescent | 69% |
The table below shows the LRV difference between the photoluminescent material and different colours of anti-slip material used in Ecoglo step edge products.
Internal Contrast by LRV Difference
All regions except Australia (LRV difference between anti-slip material and photoluminescent material)
| Product | LRV Difference |
| E3-071 and E2-071 (Black anti-slip) | 64% |
| E3-061 and E2-061 (Grey anti-slip) | 50% |
| E3-051 and E2-051 (Yellow anti-slip) | 24% |
