A typical "regular" COB LED flashlight can be shown to produce 5-7 times or more UV (of the appropriate wavelengths to cure resin) than the actual printer light source, this can be demonstrated with a UV power meter, easily obtainable from Chi-Tu and others. Good practice is to always check LED (and other) light sources in print rooms for this!
I guess those Philips bulbs have more output at lower wavelengths than other lamps. But ALL white LEDs have some output at the wavelengths used by 3D printers (405nm), so this will happen to all resins if you wait long enough.
Probably, But I found that the Sirayatech Blu and Phrozen Hyperfine react quite fast. As it will cure on the build plate just while I have the hood off to remove the print. Using the smart lights set to red makes it safe to work in the room. But it's a little difficult....
@@J3DTech I've used Siraya Blu a lot and never noticed anything like that. I guess it depends on the exact LEDs used and the light intensity where the resin is.

what the actual fuck! thanks for letting us know!
I have Yee lights I set to red and this stops it. THis way I'm able to post-process Blu with no issues.
@@J3DTech Took your notes and was able to continuing using this resin, thanks for responding to my facebook post
Thank you! ('I'm not crazy)
