Quality of light measured is measured in CRI (Color Rendering Index), and quantity of light measured in LPW (Lumens per Watt).
So, What Makes Sense In A Low Level Scenario Of Less Thank 12'?
Here is an average comparision;
T12 = 62CRI
T8 = 85CRI
T5 = 85CRI
T12 = 78LPW
T8 = 90LPW
T5 = 99LPW
T5 in this setting barely beats T8 as far as CRI and LPW values. If you didn't understand the numbers and compare all of the variables, you could get stuck with lighting that costs much more.....and you wouldn't need it.
With the numbers being this close, you could never justify the substantial increase in fixture, lamp and ballast costs which is what you would get with the T5 in this case.
Where is T5 Better?
While it obviously isn't a good idea to switch from T8 to T5 in the above scenario, it would be very good if it were a switch from T12 to T5 standard output lighting.
T5 standard output lamps have their place, it's just understanding the applications and the desired results. We recommend always using a qualified lighting consultant or designer. Guessing on the right kind of fixture can cost you dearly. .
Their experience can help in lighting layout, application, and help with knowing what incentives and rebates your business will qualify for.
