35% tint is darker than 30% tint. The percentage value indicates the amount of visible light that the tint allows to pass through the window.

• A 30% tint allows 30% of visible light to pass through and blocks the remaining 70%.
• A 35% tint allows 35% of visible light to pass through and blocks the remaining 65%.

Therefore, 30% tint is lighter (allows more light to pass through) compared to 35% tint.

While the difference in darkness between 30% and 35% tint may be subtle, it can still have noticeable effects on visibility, glare reduction, and privacy. It’s essential to consider your specific needs, preferences, and local regulations when choosing between these tint percentages for your vehicle or building.
