FormulaOne posts a new spec sheet
Shade-level numbers for all four families, on the same test basis as LLumar and SunTek.

- Logged here
FormulaOne's new automotive spec sheet (LLSP0037NA, October 2026) gives shade-level TSER, IRER and SIRR for Stratos, Pinnacle, Comfort and Classic, measured to NFRC guidelines on 6 mm clear glass with infrared defined over 780–2500 nm. That's the same basis LLumar and SunTek use, so the three Eastman brands compare directly.
One caution is printed on the sheet itself: the Stratos 25 figures come from product development and are marked subject to change.
What we updated on Mr. Window Tint
- All four FormulaOne families are now fully published. Stratos tops the line at 65% TSER and joins the "Highest heat numbers" set on the comparison page.
