Can I buy the recommended product here?
Not directly. The service helps you understand what kind of bulb or lighting product you need, and may point you toward stores or listings that match your result.
What is the difference between the tool and Lighting School?
The web app helps you find a suitable product based on your selections. Lighting School is the educational part of the site, where you can learn how home lighting works and understand terms like lumens, Kelvin, dimming, and bulb types.
What is Lighting School?
Lighting School is the educational part of the site. It explains how home lighting works, answers common lighting questions, and helps you understand lighting terms in a simple way.
What are Buyers Guides?
Buyers Guides are longer articles that explain products, features, and things to consider before you buy. They are meant to give you extra context beyond the quick recommendation tool.
Why do some options become greyed out?
Some choices are disabled because certain combinations do not work well together. This helps prevent mismatches and makes the final recommendation more reliable.
What if I cannot find an exact match?
If you cannot find an exact match, try selecting the closest option and compare it with the markings on your current bulb or fixture. The service is designed to guide you, but final verification is always recommended. You can continue from the web app.
What if my old bulb has no readable label?
If the label is missing or worn out, the tool can still help you narrow down the likely options based on shape, socket, usage, and brightness. It is still best to confirm fit and electrical details before purchasing.
Does it work for all lighting setups?
It works best for common home lighting situations. If you have a special installation, built-in LED fixture, unusual transformer, or non-standard setup, you may need to double-check the technical details manually. The terms page may also be useful for understanding the scope of the service.
Can I use the service on mobile?
Yes, the service is designed to work on both desktop and mobile devices so you can use it wherever it is most convenient.
