Anyone know the expected lifespan of these vents? How good is their ability to withstand UV light?

Mine have only been in for a couple of years, but have no material degredation yet.

Hi, I installed 3 of them in Kauai, Hawaii, 9 years ago. This past fall we had a huge storm & the top covering of all 3 cracked & parts of them blew off.We ordered new vents, installed just the top part on the existing bases (which were under the roof shingles) and all are now perfect. Do you get constant sun, salt, & breeze? We have no way of knowing how long the new ones will last, but if the base is still good, we will just replace the top again, because I LOVE these vents, they are above bathrooms & we do NOT have 1 speck of MOLD. Hope this helps, and Good Luck with your project! Lucy Hi, I installed 3 of them in Kauai, Hawaii, 9 years ago.

i installed two on a shed roof two years ago. im very happy with them. its hard to say how long they can hold up against the sunlight but id guess 5 to 10 years maybe more.

I have three that were installed about 15 years ago. Stood up to UV fine, but a severe hell storm took them out last year. Had to replace roof as well.

I have only had these for lass than a year so I have not had any sun fading or cracking. I am more concerned about roadsalt here in our PA winter climate.

Glad to assist :). The UV bulb is rated to last 10,000 hours. This can vary depending on amount of usage. The retail value of the UV bulb is $12.50 per unit. However, if a customer purchased the air purifier from us, then we sell them at a wholesale cost of one UV bulb at $4.50 plus $2.93 shipping via USPS first class mail within the USA only. Thank you :)!

Well on my civic and bimmer it's lasted easily over 6 months and the clarity it still awesome. Even if it was an annual thing you did I'm sure your lights would look close to factory. Adding a clear coat will extend the yellowing / haze caused by UV. The system is well worth under 20 bucks. Id say aim for once every year and just keep your eye on it. Some material could react slightly different than others.

Hi Sandra, I'm not sure about any UV issues regarding the usage of these lights. There are numerous studies on the benefits of the red lights and blue lights. I would suggest asking the seller. Good luck.

I purchased 2 about a year ago and they are still shining bright. The deal is a year isn't that long and further, I use them as reverse lights for my Jeep so they aren't on all that often. I wanted to chime in though because I am happy that they've survived such a harsh condition. The Jeep is never garage, I live near the coast (fog and salt water), and I take my Jeep off road regularly.

I think it might depend on, not only how long they are exposed to sunlight, but also other environmental factors (humidity and bioregion). The manufacturer claims that UV protection is included in the manufacture of the product, but research that I did suggests that they will still begin to deteriorate in a matter of months. Ours were out in the open for most of an Oregon summer filled with moist dirt, and seem to be ok so far.

I just installed four of these to replace the same model in our Solar backup system. The previous ones lasted 10 years on float with deep discharge due to power outages maybe 1-3 times a year , so I'm confident these will last as well.

Mine did over the summer. I really noticed it when I bough new ones for my patio furniture. But I also live a 7000 feet where UVs are high The material though has held up through high winds, hail and sun.

Hey Eric, I installed them about 6 months ago and they're just fine. There have been no problems with condensation, discoloration or fit. It's definitly a peace of mind purchase.Best regards

I have mine outside, they are not a water tight fixture but they are well protected from the elements. I have not had any problems, they have been up for about 3 months. So far so good!!

According to installation instructions, the unit is powered continuously, that is to say, once installed, you plug it into an available 115 vac outlet. That means that the operation of the UV unit is not associated with heating or cooling. The effective life of the bulb in continuous operation is about a year, so I plan to replace the bulb as part of my annual routine HVAC maintenance. The effectiveness of UV light on mold is unaffected by temperature. I am satisfied with the ease of installation and operation of the unit.

Anthony, I'm a bit slow on installing these, I bought 8 fixtures last year and another 2 recently. T8 fixtures are supposed to work well in low temperatures (20 F) so I'm trusting the liturature I read and what I've heard from coworkers enought to buy 10 of these fixtures. Sorry I don't yet have first hand experience.

I have two exterior security lights with these bulbs and neither owner's manual indicates life expectancy. However, the first light I purchased has been in operation for the past year and a half and the original bulb is still going strong. I liked the first light so well that I recently bought a second. They put out plenty of light and cast a sort of red/orange glow so as to not reflect or ruin night vision. I would highly recommend them! Johnny

We have been using about a dozen for 6 months no problems. I would think the would last several years because they are LED. The plants seem to respond well.

Should last for years IF they are in a sealed box. If they are exposed to light its not good.
