If you are in the business of recommending or specifying lighting for your clients, how do you know that you are getting the correct information from your lighting manufacturers? Everybody is trying to sell you a product based on some assumed efficacy, rated life or special feature. How do you know that you are getting the right data?
The adage of caveat emptor – let the buyer beware – certainly rings true when it comes to most lighting manufacturer’s data sheets. Most contain basic information on things such as form factors, lumen packages, energy used, options and accessories, and the L70 life of the luminaire.
At first glance, they all look great with impressive LPW calculations and L70s, so you happily specify the product only to be disappointed when it doesn’t perform the way that you thought it would. Remember, the client is eventually going to point some fingers. Do you want them to be pointing at you?
The following practice is very common when it comes to the LED high bay sector – it seems to be a liar’s paradise.
