LLumar CTX vs IRX: Ceramic Tint Tiers Compared
LLumar IRX is the stronger film, rejecting up to 88% of infrared heat against CTX's 69%, and its warranty is explicitly transferable to a new owner, but CTX is the better fit if you just want a genuine ceramic film at a lower price and do not need IRX's extra heat rejection.
Both are LLumar's own nano-ceramic automotive films, not a ceramic film next to a cheaper dyed or carbon product, so the comparison here is about how much extra heat rejection and warranty flexibility IRX actually buys over CTX, and whether that gap is worth the price difference most installers quote between the two.
IRX is the film to pick if heat rejection or warranty transferability matter to you, rejecting 19 points more infrared heat than CTX and backed by an explicitly transferable limited lifetime warranty, for a typical $100 to $150 premium on a full vehicle. CTX remains a solid, genuinely ceramic film for buyers who want to keep the budget tight and do not need the last 20% of heat performance. Neither is a bad choice; the decision comes down to how much you value peak heat comfort against a modest price gap.
CTX and IRX, side by side
CTX is positioned as LLumar's value ceramic film, built with nano-ceramic technology that blocks heat even in its lightest shades without the reflective look of older metalized tint. IRX sits above it as LLumar's flagship infrared-rejecting ceramic line, using a more concentrated nano-ceramic formulation specifically tuned to target the infrared wavelength that heats a cabin, which is where its higher rejection numbers come from.
Both share the same core advantages over dyed or carbon film: no signal interference, 99% or better UV rejection, and a scratch-resistant topcoat. The difference is entirely in how much infrared heat each one actually stops and what the warranty covers if you sell the car.
| Film | TSER | IR rejection | VLT shades | Warranty |
|---|---|---|---|---|
| CTX | Up to 58% | Up to 69% | 7 shades, roughly 15% to 50% | Manufacturer-backed, confirm transfer with dealer |
| IRX | Up to 63% | Up to 88% | 7 shades, 6% to 50% | Limited lifetime, explicitly transferable |
How much heat rejection you actually feel
The jump from CTX's 69% infrared rejection to IRX's 88% is noticeable on a hot afternoon, particularly on the front windshield strip and front side windows where sun exposure is most direct. Drivers who have tinted a car with CTX and later upgraded to IRX on a second vehicle consistently describe IRX as meaningfully cooler at the same VLT, since the extra infrared blocking is doing work independent of how dark the shade looks.
If your main reason for tinting is comfort in a hot climate or reducing dashboard and seat fading from sun exposure, IRX's higher number is the more direct path to that outcome. If your priority is mostly UV protection and a darker look for privacy, CTX delivers nearly the same UV rejection at a lower price.
IRX's extra infrared rejection matters most on the windshield strip and front doors, where direct sun exposure is heaviest.
The warranty difference that matters at resale
LLumar states IRX's limited lifetime warranty is transferable to a new owner, a detail worth confirming in writing with your installer but one LLumar backs explicitly in its own product materials. CTX's warranty language is less specific and generally directs buyers to the installing dealer for exact transfer terms, which means two CTX installs from two different dealers could carry different resale-transfer policies.
This matters more than it sounds like on paper. If you plan to sell the car within the warranty window, a tint job with a documented transferable warranty is a small but real selling point, and it is specifically an IRX strength rather than a CTX one unless your dealer confirms otherwise in writing.
Price difference installed in 2026
Both CTX and IRX fall within Coateau's $450 to $700 ceramic tint range for a standard sedan, with SUVs about 1.2 times that and trucks or large SUVs about 1.4 times that. Within that band, CTX typically prices toward the lower end as LLumar's value ceramic tier, while IRX sits toward the upper end as the flagship film, a gap installers commonly quote in the $100 to $150 range on a full vehicle.
That gap is smaller than the difference between LLumar's cheapest film and a premium 3M or XPEL install, which is part of why IRX is a reasonable upgrade to ask about even if you came in planning on CTX.
Which one to actually book
Pick IRX if you live somewhere hot, spend real time in direct sun, or want the stronger resale story from a transferable warranty. Pick CTX if your budget is the deciding factor and you mainly want a genuine ceramic film with solid UV protection and a clean look, since the gap in UV rejection between the two is negligible.
Whichever you choose, check /tools/window-tint-laws for your state's minimum legal VLT before settling on a shade below 35%, since both films come in shades darker than what many states allow on front windows.
Frequently asked questions
Is LLumar IRX better than CTX?
On heat rejection, yes. IRX blocks up to 88% infrared heat versus CTX's 69%, and its warranty is explicitly transferable. CTX remains a reasonable choice if budget matters more than the extra heat rejection.
How much more does LLumar IRX cost than CTX?
Installers typically quote a $100 to $150 gap on a full vehicle, with both films falling inside Coateau's $450 to $700 ceramic tint range for a standard sedan.
Does LLumar CTX's warranty transfer to a new owner?
LLumar's CTX materials direct buyers to the installing dealer for exact transfer terms, so it is not guaranteed the way IRX's transferable limited lifetime warranty is. Get the answer in writing before paying.
Do CTX and IRX both block phone and GPS signal?
No, neither does. Both are fully metal-free nano-ceramic constructions, so phone, GPS and satellite radio pass through without interference.
What VLT shades are available in CTX and IRX?
Both come in 7 shades. IRX ranges from 6% to 50% VLT, while CTX runs generally lighter, from roughly 15% to 50%, so confirm exact shade availability with your installer.
Is CTX a dyed or carbon film?
No. CTX is a genuine nano-ceramic film, the same core technology as IRX, just tuned for a lower price point with less concentrated infrared-blocking performance.
