Denus Posted January 7, 2015 Report Share Posted January 7, 2015 A friend gave me a complete Apple IIc set with the system, monitor, stand and printer including the boxes (with the foam intact!), manuals and software. There's no damage, but the plastic is quite yellowed, so I started a whitening treatment with a UV lamp for a change (no much sun atm...). Well: it works very well: I'm quite pleased with the result. The system is ready and reassembled, the monitor is still in treatment along with some other parts and bits. Used: Osram Ultra-Vitalux 300W UV lamp and a good lamp-cage & ceramic fitting, a bottle of Oxi Kallos 12% and some time (4 hours with a lamp) Obviously the summer sun does a better job, but this will certainly do as well.

olePigeon Posted January 7, 2015 Report Share Posted January 7, 2015 (edited) Well, not necessarily. I attempted to do the same thing with an Apple //e, but I couldn't get an even whitening under the sun. The cream kept drying out too quickly, leaving streaks. Yours appears to have turned out great. I think the trick is a UV lamp, keep the stuff from evaporating. Edited January 7, 2015 by olePigeon Quote Link to post Share on other sites
unity Posted January 7, 2015 Report Share Posted January 7, 2015 Pigeon, some said plastic wrap over the gel helps too. But wow does that look sharp! Quote Link to post Share on other sites
Denus Posted January 7, 2015 Author Report Share Posted January 7, 2015 My trick is a simple plant sprayer with water. Every half hour, I spray some water on the parts and I spread it out with a brush just to keep it humid. Occasionally I have to add some cream, but not much. That's what I did during the treatment in the sun too, works like a charm (done several Mac Classics). Quote Link to post Share on other sites
Denus Posted January 7, 2015 Author Report Share Posted January 7, 2015 (edited) I don't use plastic foil anymore: the wrinkles you get with foil causes streaks. Btw: the UV lamp is also drying out the cream, hence the plant sprayer.... Edited January 7, 2015 by Denus Quote Link to post Share on other sites
techknight Posted January 7, 2015 Report Share Posted January 7, 2015 What about using liquid solution and a aquatic pump? Sprayer attachment to keep a continuous flow... Quote Link to post Share on other sites
Denus Posted January 8, 2015 Author Report Share Posted January 8, 2015 (edited) Nice idea, but then you'll need a closed room and a container to take in the liquid. That would be quite an installation. I'll stay with my method: brush for the cream and sprayer for the moisture: easy and effective. The monitor was very yellow, almost brown, but this is the result after a few hours (can't believe how nice it came out!) Edited January 8, 2015 by Denus Quote Link to post Share on other sites
Denus Posted January 8, 2015 Author Report Share Posted January 8, 2015 ...and this is the final result: I'm quite happy how the system turned out. Quote Link to post Share on other sites
unity Posted January 8, 2015 Report Share Posted January 8, 2015 What lamp did you use? It seems very effective. Only certain light wavelengths work well. And not all lamps produce the same. Quote Link to post Share on other sites
Denus Posted January 8, 2015 Author Report Share Posted January 8, 2015 I use a Osram Ultra-Vitalux 300W UV lamp: it's working great! But be sure to use a solid lamp cage with a ceramic fitting, because it's getting hot! Quote Link to post Share on other sites
Denus Posted January 8, 2015 Author Report Share Posted January 8, 2015 Oh, and I got a tan too... It's wise to wear anti-UV sunglasses. Quote Link to post Share on other sites
Elfen Posted January 8, 2015 Report Share Posted January 8, 2015 (edited) Let me throw in - The lamp bulb itself, was it a clear florescent bulb or a dark purple/indigo painted bulb? That answer there will tell me a lot. Edited January 8, 2015 by Elfen Quote Link to post Share on other sites
unity Posted January 8, 2015 Report Share Posted January 8, 2015 (edited) The specs on the lamp. UVA radiated power 315…400 nm 13.6W UVB radiated power 280…315 nm 3.0W Pretty broad specs, I like to see tighter numbers but they are just covering the entire tanning spectrum. Anything shorter than 280 is a little concerning. Edited January 8, 2015 by unity Quote Link to post Share on other sites
Denus Posted January 8, 2015 Author Report Share Posted January 8, 2015 It's a clear florescent bulb. Quote Link to post Share on other sites
Denus Posted January 11, 2015 Author Report Share Posted January 11, 2015 Whatever the thoughts regarding the given specs of the Osram UV lamp, I just treated a complete Apple IIc set with it and the result is awesome (even better than expected). So, instead of staring at the numbers on paper, rather check the archived results... This lamp cost you $40,- and a good solid industrial lamp cage approx. $20,- Add a bottle of Oxi Kallos 12% (or similar), a brush and a plant sprayer, and you're good to go.

unity Posted January 17, 2015 Report Share Posted January 17, 2015 I've been hunting for this lamp. In the US it seems $90 is common price. Not a cheap lamp! But I did fine one place online, and I am sure there are more, for less. Two lamps shipped to the US would be less than $120. http://www.svetila.com/product_info.php?language=en¤cy=USD&products_id=1170&utm_source=GoogleBase&utm_medium=BaseFeed&utm_campaign=products-EN&gclid=CJiZut3Fm8MCFQ4BaQodclIA6A Quote Link to post Share on other sites
Denus Posted January 22, 2015 Author Report Share Posted January 22, 2015 I found a German reseller on eBay who's selling this lamp for 39,- euro. (obviously, shipping costs can be too high for the US) But the link you're showing is from Svetilla: my lamp came from the very same company, and it's the best customer experience I've even had so far!Every step during the order, shipping etc was communicated to me so I was able to check the status during the whole process.

Denus Posted January 22, 2015 Author Report Share Posted January 22, 2015 Btw: is there a 110 volt version of this lamp? I didn't see one yet. Very important to avoid heating problems and worse fire and/or short circuits: use a descent lamp cage!The lamp cage must be able to handle the heat (300W). It's not that expensive: between $20 and $25, much cheaper than a new home... Quote Link to post Share on other sites
unity Posted January 23, 2015 Report Share Posted January 23, 2015 110v versions of tanning lamps simply do not produce the proper output to reach the proper spectrum. The most effective lamp will be a 220v version such as this. If 110v would do, one would see tanning beds operating at 110v. They are all 220v. Some of the big ones are three-phase 220v. I did find a US seller for about $60 each shipped. Thats a little more than the Euro sites, but not much. Quote Link to post Share on other sites
Denus Posted January 23, 2015 Author Report Share Posted January 23, 2015 I had no idea about this phenomena, it's all 220v here but It all makes sense now.So you'll need a 110v to 220v voltage converter I guess (dirty cheap though). Quote Link to post Share on other sites
Elfen Posted January 23, 2015 Report Share Posted January 23, 2015 (edited) It's a clear florescent bulb. I've been hunting for this lamp. In the US it seems $90 is common price. Not a cheap lamp! But I did fine one place online, and I am sure there are more, for less. Two lamps shipped to the US would be less than $120. http://www.svetila.com/product_info.php?language=en¤cy=USD&products_id=1170&utm_source=GoogleBase&utm_medium=BaseFeed&utm_campaign=products-EN&gclid=CJiZut3Fm8MCFQ4BaQodclIA6A Unity, have you tried looking at an aquarium supply store? They sell clear UV Bulbs and fixtures for large aquarium tank disinfecting. You put the bulb into the tank's florescent fixture, turn it on and walk away for a couple of hours. The bigger the tank, the bigger the bulb, the longer the time, but for a 25 gallon tank, its a couple of hours. This kills off the various unwanted microbes that could be infecting your tank. WARNING: Do not look at the blub while it is turned on! Denus, thanks for answer that because the aquarium disinfecting UV bulb is exactly the same thing.

unity Posted January 23, 2015 Report Share Posted January 23, 2015 Those aquarium lamps would not work, period. Quote Link to post Share on other sites
Denus Posted January 23, 2015 Author Report Share Posted January 23, 2015 I think the price wouldn't differ much anyway, so rather choose for a bulb that has been tested and approved (by me that is). Just want to clear out that the combination bulb/Oxi Kallos 12%/plant spray to keep things humidified is working great for me.Except for the bulb, this is also the method I've used last summer with sunshine, and I even did a Casio VL-Tone (VT-1) and some other things which are now snow white.I can't tell if other methods or products are working as well: it may, it may not...

unity Posted January 29, 2015 Report Share Posted January 29, 2015 My lamps came today. I decided to tap into a sub-box for a small water heater I have on the third floor. Oddly my meter is reading the output at 300v! Not sure what is up with that and not sure I want to plug a lamp into that. I know they love 230v and ideally run at 235v. But 300v seems crazy high. Not sure why its reading so high, very odd. Its a dedicated sub box to a breaker in the main box. Quote Link to post Share on other sites
Denus Posted January 29, 2015 Author Report Share Posted January 29, 2015 That will shorten the lifespan of the lamp for sure!I think you should seek for a safer option as the lamp isn't cheap.... Quote Link to post Share on other sites
