Perfect Fit

Wide selection of sizes provided a ready to order custom fit. Protective packaging for shipping assured the item arrived undamaged. Great service and pricing.


Exactly what I needed to fish off the reconditioning of my light. This lens was exactly like the original in every way and, judging by the nasty original it replaced, that one must be at least 20 years old or more. Shipping was in a very secure double box with lots of padding. A+ experience.

Under cabinet light lens

Perfect fit! Love them I really appreciated that I could order precise measurements!

Highly recommend 1800ceiling!

In addition to having the unusual size of cover I needed where other major distributors fell short, the items came rapidly and beautifully packaged. Egg crate fluorescent light covers of this caliber are usually reserved for commercial use. I recommend this cover over traditional brittle plastic lenses for residential use. So refreshing to work with a small business that really cares. They have brightened my home office and exceeded expectations.

Best Invention EVER!!!

This roof fix is incredible..... I can't believe how well this ceiling fix, fixes leaky roofs. This product is a handyman's dream to say the least. This products ability to solve the expensive task of resealing a leaky roof, and the pleasing ascetics of a water catch rather then the moldy saggy ceiling tiles is a big plus.

Excellent Product

I was in desperate need for a return duct scoop, and this was exactly what I needed to direct hot air away from my rig. Order was filled quickly, I paid extra for overnight shipping and received the item very quickly. Thank you.

Reversed Lens

Manufacturer extruded the plastic lens with the corrugation on the inside rather than the outside to match original equipment. It is wrong side out.


Very quick shipping
