When someone asks whether a given LED is compatible with their system, there are two different questions being asked - Does this system supply what the LED needs to work? - but also, Is this LED going to perform in a way that fits the site's needs? These questions have very different answers.
- Figuring out whether a system supplies what the LED needs can almost always be figured out from the datasheets of the products involved. Knowing an exact luminaire spec can make a reference against an ETC control very simple, and determining whether two products are compatible on-the-page is very easy without testing.
- Figuring out whether an LED performs in a way the site needs cannot be known without testing, even if the outputs of the control system are known to match up with the inputs of the luminaire as determined above. LED dimming is unfortunately not as simple as with incandescent - dimming is no longer a physical interaction between power and heat shedding, but a program made with circuit boards and chips. Any design change can have a major impact on actual performance, so performance cannot be known ahead of time and similar products won't necessarily perform the same.
This reality is why we provide testing as a free service, and always recommend it whenever possible. This guide is a great resource in knowing how to send test samples, and what actually needs to be sent.
