In this context of this thread, this is an awesome resource! Newbie here, but I just learned about CRI. Your tool is very featureful for a tech/power user.
If you want a text wall of UI suggestions: Move the top buttons to a left side menu that always-show their checkboxes (like newegg/amazon), so that the button meaning can be learned from its options. Perhaps describe every item with hover text (eg title attrib). Perhaps put CRI in the product description, since everyone seems to care about it. Combine weather-resistant/weatherproof/water-resistant to whatever degree possible. I couldn't find any waterproof high-CRI, for what that's worth. Another idea is a "purpose" category where you could decide what features would be ideal for things like hiking, backpacking, swimming, home use, car use, etc.
'Always show checkboxes' was something I tried early on. It simply doesn't scale well. There are already more than 200 checkboxes and 10 double-ended sliders.
Each single checkbox presented is the most important feature for someone. It is interesting that the HN crowd is stressing high CRI but many feel the reduced efficiency is not worth the trade off.
Though generally if you are serious about nice CRI you will end up buying a regular light and swapping out the LED.
It might be worthwhile for me to provide levels of detail. Like in your case, you don't care if something is IP-X7 or IP-X8, you just want waterproof. And no good manufacturer would say "waterproof" since the word doesn't mean anything. Though that sort of modal configuration screens (advanced mode, etc) are almost universally considered bad UI on HN, so who knows.
another UI note... dim selections that are eliminated by previous choices. Example: type=headlamp. Then when I pick battery, don't let me pick 4xD because there aren't any results.
