Ikea JANSJÖ light

[Mainecoonmaniac]

I think the Swedes and the Chinese are teaming up against the world. Swedish design and Chinese factories churn out cheap temptations for us making us empty our bank accounts. I do notice the only thing not Chinese made at Ikea is the food. You can feed a family of 5 on $5 with hot dogs, sweet rolls and soft-serve ice cream cones washed down with lingonberry juice.

No, you need an ultra violet light for that.

No kidding. A lot of "white" LEDs are actually UV LEDs with a phosphor. If you want to argue about it, try contacting this guy:

You are right Jerry! You can cure yellow tint from Takumar lenses with this lamp. SMC 50/1.4 was very quick job with few days of exposure. 2/35 Super Takumar took weeks to clear out. Not sure does LED emits less UV with use or 2/35 had stronger yellow tint than 1.4/50.

People used to console themselves thinking that Japanese manufactured goods were inferior and they were allowed to take the cheap end of the market, until people realized they weren't inferior but superior, more innovative, and less costly than the western manufacturers could produce, now they have taken over the World, and the same applies to China they aren't going to be satisfied with the cheap end of the market for ever.

That's right. Remember, iPhones and iPads are made in China.

I bought one of these Jansjö lamps in Ikea Cardiff when I was visiting recently, they were selling the silver ones half price for £4.99, (yes I had the meatballs mashed potatoes and apple pie) I indeed used it to remove the yellow caste in my Canon FD35mm f2 lens and after about thirty hours exposure it worked like a charm and the yellow is completely gone now.
