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.

Fit check = great
Size: X-Large, Color: Light Grey Vertical Stripe
Happy to finally find a great shirt fit for both business and casual looks. This shirt line is made in Sri Lanka (not Bangladesh). It has a great fit around the shoulders and chest for a 40 year old American male. It fits true to form and was recommended to me directly by Grok AI based on my exact waist, chest and neck measurements. It doesn't pull tight across the chest, and fits really nice with a sport coat. It's comfortable and breathable, the fabric is thick and high quality. You can wear this tucked or untucked depending on the attire you need. I bought 2 and will definitely buy the rest of the color line up. I'd love to see more colors and patterns available in this fit.

Highly Recommended Dress Shirt

Honestly, I Love It. Fits Great, Neck Isn't Too Tight Like Most Shirts, And It's Comfortable. It Is 100% Cotton, So Dont Forget To Iron It Before Wearing It. High Quality Dress Shirt. Highly Recommended.

Surprisingly good shirt for the price
Fit Type: Regular Fit, Color: White, Size: XX-Large
I’m generally pleased with my purchase. I got a 2XL because the website it would fit my neck. Around the waist it fit similar to Amazon Essentials work shirts (like mechanics use which I find comfortable). It was snug around the waist when sitting, but I can’t complain because I have a belly. I did find the neck snug when buttoning the top button so it means the neck is 18 or 18.5 and I wear a 19/19.5 to have 1-2 fingers space in the collar. The shirt is surprisingly thick like Amazon’s work shirts, much thicker than other dress shirts from another brand. And I am pleased that this shirt has button holes like other Amazon shirts does, all vertical button holes except the last one at the bottom which is horizontal. That feature keeps the shirt from unbuttoning itself during daily movement at the office. A very nice feature! I was a little disappointed in how it was packaged however but I have to press and wash it anyway.
