However, the temperature should be noted. The filter can withstand a maximum of 80 ° / C. However, I cannot know exactly which filter was installed in your projector. **Q: Would this be suitable to reduce glare from a smart phone mounted on the handlebars of a bike?** A: Unfortunately, this is not an application for this filter. **Q: Do you have the same specs self-adhesive filter but for circular (not linear) polarisation?** A: Yes, please look for type ST-37. But only none adhesive. **Q: Will this work on a garmen gps map 178c. Is this self adhesive?** A: Type ST-38-20 is non-adhesive and Type ST-38-20S is single-sided self-adhesive. The polarization axis must be found by turning the filter. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality, self adhesive make this very easy to use. *by on Reviewed in the United Kingdom 12 April 2020* Good quality, self adhesive make this very easy to use. ### ⭐⭐⭐⭐ Four Stars *by on Reviewed in the United Kingdom 11 April 2018* Expensive for the size.
