So what is Spectra PhotoSync? We have been in this industry since 97 and have used / tested just about everything out there. For window tint, the technological landscape has changed drastically over the past 10 years. Below is a synopsis of the evolution:

Dyed Tint - (aged / basic technology) - depending on the manufacturer, it will change color (ahem purple) and bubble over time. It also provides very little in heat rejection and durability.

Metallic / Sputtered - this type of technology was brought about because of the poor heat rejection of dyed products. Depending on the brand, metallics will change over time in color and may bubble, but is generally more durable than dyed products. Heat rejection is improved here; however, you will get problems with signals such as keyless entry, am / fm, etc.

Ceramics / Nano Ceramics - this was a technological breakthrough some 10 years ago, which offered metallic product performance without signal disruption. However, there were two key companies that claimed no signal interference; yet with real world experience with BMW and Audi owners, there were apparent issues with keyless entry system interference and AM waves.

IR Nano - this is where Spectra PhotoSync enters the market. Superior heat rejection, signal free technology, and the ability improve its performance when exposed direct sunlight. Rejects up to 98.5% of infrared rays and total solar energy rejection in the 70s%, this product outperforms everything we've tested.

Now, on to the B7!!!:

 

Looks good. Always loved those Alpina 7's.

 

And the reason we so religiously believe in Spectra Photosync:

 

Windshield with Spectra PhotoSync 75

 

looks good, but I prefer B3 alpina

 

Nowadays, it's all about performance and technology with window film. Spectra PhotoSync far exceeded our expectations in both fields. If you are not close to us in Northern California, and seeking an authorized dealer, contact the manufacturer:

We recently conducted a test to see how hot the Tesla Model S gets in the rear. There is a general consensus among Tesla owners regarding too much heat build up. For the rear hatch of the Tesla Model S, there is an option for rear facing seats for children. Owners of the Model S have been complaining and executives at Tesla even know of this issue. With that said, we decided to conduct a test to measure the ambient air temperature of the rear hatch. Tesla's rear hatch glass is a laminated glass that has a metallic coating to it to reject some heat; however, even this is not enough from our findings.

Though this is not a 991, we believe it is necessary to show the efficacy of every product we carry at Premier. Below is our test:

Test Subjects - 2 Tesla Model S
Tesla 1 - factory laminated OEM Glass with metallic coating
Tesla 2 - Spectra PhotoSync 45 installed to the side glasses + rear hatch

30 Minute Test in the Rear Hatch with both vehicles side by side
Duration: 30 Minutes
Time of Test: 3:35 pm
Exterior Temperature: 88 degrees
Purpose: Compare air temperatures inside hatch between vehicle with no window film and the other with Spectra PhotoSync installed

Here are the two test mules:


Test Vehicle 1 - No Film
Start off at 84 degrees


In just 3 minutes the temperature rose to 92 degrees


Close to 7 minutes, the air temperature rises to 105 degrees


At the 15 minute marker, temperature is at an unbearable 123 degrees


26 Minutes - Temperature now reads 136 degrees


At the end of the 30 minute test, it is a scalding 140 degrees, which is the reason why leaving children in a vehicle can be a fatal mistake.
