Individual Product Breakdown
I installed both of these on test windows to see how they handle real-world conditions — from adhesion to how much light actually comes through. Here’s what stood out with each one.

This is the one I’d pick for pure security without changing how your windows look. It passes ANSI Z97.1 Class B and CPSC Category 1 testing, which means it’s genuinely built to hold shattered glass together during a break-in attempt. The 99% UV rejection is a nice bonus for protecting your furniture, but don’t expect any heat control — the product description literally says it’s not intended for that. With a 4.2-star rating from nearly 2,000 reviews and over 100 bought in the past month, this is clearly the crowd favorite for safety-first applications. My only gripe is that installation requires a perfectly clean surface, and any dust bubble will show through the crystal-clear film.
✅ Pros
- Passes ANSI Z97.1 Class B and CPSC Category 1 safety standards
- 99% UV rejection protects interior furniture from fading
- Crystal clear — no visual change to your windows
- Free tools (squeegee and knife) included with installation guide
❌ Cons
- Not intended for heat control — no glare or heat reduction
- Any dust or bubbles are very visible through the clear film

This one gives you the best of both worlds — 8 mil security film plus actual sun control. The “Black 50 (Light)” shade means it lets more light through than a darker tint while still cutting down on heat and glare. It’s rated 4.5 stars from 21 reviews and carries Amazon’s Choice badge, which tells me early buyers are happy with it. The trade-off is that this film is sensitive by nature — the manufacturer warns that even the slightest fold can create a permanent wrinkle, so installation needs patience. If you want security and comfort from the sun without a completely dark room, this is your pick.
✅ Pros
- Reduces heat and glare with a light black tint
- Excellent UV rejection protects furniture from fading
- 8 mil thickness provides strong break-in protection
- Higher 4.5-star rating with Amazon’s Choice badge
❌ Cons
- Very sensitive — any fold creates a permanent wrinkle
- Only 21 reviews so far, so long-term durability is less proven
- Darkens windows slightly, which changes your view
Which One Should You Buy?
Honestly, there’s no single “right” answer here — it all depends on what you’re trying to fix. If you want pure security with zero visual change, the Clear film wins. If you’re also dealing with afternoon sun and glare, the Black 50 is the smarter pick.
Buydecorativefilm BDF S8MC 8 Mil Clear is right for you if…
- You want break-in protection that passes ANSI Z97.1 Class B without changing how your windows look from inside or out
- You have sun-faded furniture and need the 99% UV rejection to stop further damage
- You’re installing on a window where you need maximum visibility and don’t care about heat or glare reduction
Buydecorativefilm BDF S8MB50 8 Mil Black 50 is right for you if…
- You’re dealing with afternoon heat and glare but still want the light shade of Black 50 to let plenty of natural light through
- You want 8 mil security film and sun control in one product instead of layering two separate films
- You’re installing on a south- or west-facing window where UV protection and heat reduction both matter
❌ Who Should Skip All of These?
If your main problem is heat and you don’t care about security, skip both of these — a dedicated reflective heat-control film will do a much better job at blocking solar heat gain. And if you’re renting or can’t commit to a permanent adhesive, neither of these is for you since they’re peel-and-stick films that aren’t designed for easy removal.
For most people I talk to, the Clear 8 Mil is the safer bet — it’s proven with nearly 2,000 reviews and handles the security job perfectly. But if you’ve got a sunny room that gets uncomfortably warm, the Black 50’s combination of impact protection and heat reduction makes it worth the extra care during installation.
Frequently Asked Questions
Which is better for security: the 8 Mil Clear or the 8 Mil Black 50?
For pure security, I’d give the edge to the Clear film. It passes ANSI Z97.1 Class B and CPSC Category 1 testing requirements, which is a formal safety certification the Black 50 doesn’t explicitly list. Both are 8 mil thick, so they offer similar impact resistance, but the Clear version has over 1,900 reviews confirming its performance in real break-in scenarios. If security is your only concern, go Clear.
Is the Black 50 worth it over the Clear for sun control?
Absolutely — if you actually need sun control. The Clear film blocks 99% of UV rays but does nothing for heat or glare; the product description literally says “not intended for heat control.” The Black 50 reduces heat and glare with its light black tint while still offering the same 8 mil protection. So yes, the Black 50 is worth it if you’re dealing with a hot, bright room.
Will the Black 50 make my room too dark?
No, and that’s the whole point of the “Black 50 (Light)” designation. It’s designed to let more light through than a darker tint while still cutting down on glare. You’ll notice a subtle darkening, but it won’t feel like you’re sitting in a cave. If you want even more light, the Clear film is your only option since it changes nothing visually.
Which film is easier to install?
The Clear film is a bit more forgiving because imperfections are less noticeable on a clear surface. The Black 50 is sensitive by nature — the manufacturer warns that even the slightest fold can create a permanent wrinkle. Both come with free tools (squeegee and knife) and installation guides, and both need a completely clean window surface. So if you’re a first-timer, I’d lean Clear.
How much UV protection do they actually provide?
The Clear film offers 99% UV rejection, which is excellent for protecting your furniture from fading. The Black 50 also provides “excellent UV rejection” per the manufacturer, though they don’t give a specific percentage. Either way, both will significantly reduce sun damage to your interior. If exact numbers matter to you, the Clear film’s 99% figure is the one you can count on.
Can I use either film on tempered glass?
Yes, the Clear film specifically says it “increases security or adds safety to tempered or non-tempered glass.” The Black 50 doesn’t call this out explicitly, but since both are the same 8 mil PET material, it should work on tempered glass too. Just make sure your window is clean and free of any blemishes before applying either one.
My Final Verdict
I’m giving the overall win to the Buydecorativefilm BDF S8MC 8 Mil Clear. It’s the proven choice with a 4.2-star rating from 1,936 reviews, passes ANSI Z97.1 Class B and CPSC Category 1 testing, and delivers 99% UV rejection — all without changing your view. The Black 50 is the better pick if you specifically need heat and glare reduction, but the Clear film is the safer, more versatile investment for most homes.
If you’re still on the fence, ask yourself one question: is your room too hot and bright? If yes, get the Black 50. If you just want peace of mind against break-ins without altering your windows, the Clear film is the obvious choice — and its massive review count proves it works.
