I have a reading light whose temperature is very high even on the lowest setting (marketed as 3000K, but feels higher). I want to filter away all of the blue light it emits. My first idea was to get a piece of transparent red plastic, (similar to those Japanese "checksheets") cut it to size, and glue it to each light source.
Here is what the object looks like. Skip to 1:35 for a view of the parts I'd have to cover. https://youtu.be/oY0W-FDZ8bU?t=95
- Is there a better way of doing this? For instance using some kind of paint or gel?
- If not, is there a better material to use than plastic?
- Would it have to be red to block out all of the blue light, or could orange still get the job done?
