DESCRIPTION

COPPER HEAD BLACKOUT LED UPGRADES.

When looking for an easy option for better-performing headlights for your vehicle our STEDI™ Copper Head Blackout conversion kits are a simple Plug & Play upgrade that is as simple as changing over a factory globe.

+200% LIGHT VOLUME.

On average most halogen 55W lamps will produce 850 Lumens per lamp, compared to 1,760 Lumens per lamp for our Blackout Copper Heads. Our Lumens are not to be confused with the exaggerated numbers by other vendors, our Copper Heads are properly tested inside of a Photometric Sphere. All that brightness is useless without exacting light distribution, and this is where we really lead the market. We’ve put lots of work into perfecting the beam geometry to ensure that our kits won’t cause glare and cause unwanted light scatter. We back this up with a 30-day money-back guarantee.

BUILT TO LAST.

We’ve moved away from active cooling (fan kits) and adopted passive cooling. Passive cooling not only substantially increases reliability, but the flexible cooling belts of our Copper Heads offer the ability to retain the use of the factory dust caps maintaining the water & dust resistance of the headlight housing.  With a lower profile than that of a fan-cooled kit, compatibility and ease of installation are also much wider.

Comfortable from the first night
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
I found them comfortable and with good support for the head and neck. They are wide in size and feel soft when lying down. After several days of use they continue to retain their shape without problem.

Not as Firm as I had hoped
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
A good pillow. However, there is quite a difference between the manufacturer's and my idea of "medium firmness". I found this pillow much softer than I had anticipated. I'll have to go for firmer for my next purchase.

I admit when I was wrong.
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
3/29/26 - I took the pillows and put them in my dryer on steam refresh for the default 10 minute cycle. OMG - they fluffed up and evened out to be soft and comfortable, no lumps whatsoever. If you like a soft pillow with some support, but not firm support, THIS is what you want. I am truly amazed. ================================================== Previous review---They arrived in a vacuum seal bag. When you cut the bag and they inflate, they inflate lumpy like. Some areas are thick and some have to fill so, not very good. I am going to try washing them and drying them to see if they fluff up better. Will post the results in a day or two.

Immediate neck and back pain
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
Nice full pillows that holds its shape, BUT was NOT good head and neck support. I noticed an immediate difference. From non existent to growing neck pain in the first night’s use, through the week.

Soft and comfortable
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
These pillows are incredibly soft and comfortable. They provide great support while still feeling plush and cozy. I’ve been sleeping much better since I started using them.
