So LED bulbs emit less UV?summoner wrote:It is funny you mention that, I just yesterday ordered new LED bulbs to replace all the halogen bulbs in the spot lights in my hall and living room for that exact reason. All the windows in the house are either UV, or have a UV film. Next will be slowly replacing all the other bulbs from CFL to LED... Damn things are pricey!CrustaR wrote:Also, even keeping a print out of direct sunlight will not prevent UV damage - interior lighting can also emit UV rays.
Do you need UV protection?
I was also under the impression that Museum Glass UV protection is about as good as it gets as far as glass is concerned. Tru Vue Conservation Clear is also advertised to offer 99% UV protection, and that is what I am inclined to go for at the moment.FramerDave wrote:Are you talking about Museum Glass, the glass with the anti-reflective and UV filtering coatings?

My own experience with UV rays on other stuff (DVDs, books, cheap posters etc) is that they can do some noticable damage over the long run. I have some books and DVDs kept in a bookcase with a glass door. Said bookcase is out of direct sunlight, although natural light does enter obviously. Over the years, the fading is noticeable. You can see a clear difference between the spine (which is exposed) and the front covers/backs (which are covered). Certain colours are also more susceptible to fading it seems. If it is a print I treasure and hope to display with some permanence, I would certainly go for UV protection.
What I need to decide is whether to opt for UV Glass (Conservation Clear) or UV Plexiglass/Acrylic. Anyone has any thoughts about that?
Most, but not all, are UV free, or virtually UV free. If you are buying some to be UV free make sure the package, or product listing, states that they are UV free.Mertai wrote:So LED bulbs emit less UV?summoner wrote:It is funny you mention that, I just yesterday ordered new LED bulbs to replace all the halogen bulbs in the spot lights in my hall and living room for that exact reason.

The last ones I purchased where these. http://www.lightexports.com/servlet/the ... %2C/Detail
In the description was this "Emits virtually no UV/IR light in the beam." I am taking that to be a better thing than the bulbs that I had prior.

If you are comparing framing-quality UV filtering glass (such as Conservation Clear) and acrylic, then the UV protection is the same. For me the deciding factors would be the size, weight and concerns about breakage.Count wrote:I was also under the impression that Museum Glass UV protection is about as good as it gets as far as glass is concerned.

Generally glass is available up to 40x60, so anything larger than that pretty much requires acrylic. Even so, glass that size makes me nervous as hell; it's a lot of broken glass to deal with if something happens. Even on smaller frames acrylic can be an advantage since it's 20 times more shatter resistant than glass. If the frame is going to be shipped, definitely use acrylic. Also consider that if glass breaks (no matter the size) the shards can tear or scratch your art.
Acrylic is also about half the weight of glass, making your frame easier to handle and hang. Plus it lets you use a slightly smaller frame if you absolutely insist on a skinny little frame.

this is actually true, but its less than a 1% differenceCrustaR wrote:This is the first I have ever heard of that...Do you have any info that backs up that claim?suchanoo wrote:Museum grade UV isn't quite as effective at blocking UV waves as standard UV.
On the TV website, they both have the same numbers, but they don't break it down in to the any decimal places, so I guess there could be a minor difference.jamesgunter wrote:this is actually true, but its less than a 1% differenceCrustaR wrote:This is the first I have ever heard of that...Do you have any info that backs up that claim?suchanoo wrote:Museum grade UV isn't quite as effective at blocking UV waves as standard UV.

Conservation ClearIWish wrote:As far as I know, you would need to get the testing data/document from the glass manufacture(s) and compare the results.
Conservation Reflection Controll
Optimum Museum Acrylic
Conservation Clear Acrylite
Museum Glass
So lighting in the home should be LED and preferably one's which specifically do not emit UV rays?
I heard that some prefer acrylic due to it being more difficult to shatter and weighing less, although others say it scratches easily and is more expensive. Are these for the most part correct assumptions?

Any type of acrylic is always going to be more expensive than a comparable glass product due to the raw materials and processing involved in making acrylic.appletree wrote:So lighting in the home should be LED and preferably one's which specifically do not emit UV rays?

Most acrylic will scratch easily. TruVue's Optium Museum acrylic is very highly abrasion resistant. It really takes an effort to scratch it.

One of The things that I rarely see mentioned in these discussions is also the fact that regular class is a lot more breakable than the UV protected glass. Granted I get my stuff from Hobby lobby, but even in the store the girl showed me how easily the glass regular breaks compared to the uv protected glass. The frustration Of having to replace broken glass alone might be worth the additional $30 for the UV class.
Very interesting. Thanks for the information.
