Dorhui Exposure Unit for Screen Printing, 25W LED UV Screen Printing Exposure Light for Screen Printing Kit, Photo Emulsion and Cyanotypes

Bought this for Cyanotype printing - works perfectly for what I need. I cut out a hole in the top of a cardboard box and just stick this on top- strength is good. Creates pretty and well exposed prints.

I'm using this expose cyanotype emulsion. It works well for that. It feels pretty flimsy though, not sure how long this light will last. Can't complain for now though, especially for the price.

I ordered this after I saw the Speedball 's similar product .(because this one was cheaper). As you see, it is small and looked easy to set up. I have a black coffee table, so I placed my screen and printed transparency on it, then set the light approx 16" above, switched on, waited for 7 minutes, then it burned the screen successfully. The problem was no instruction came with this product, so I had to look for the information of the height and time to burn screen by myself. I have read all reviews on this page , but some said didn't work at all, some said it took for seconds, some said took 7-8 minutes, and nobody mentioned the height to set up the light, (very confused) Then I've found the chart on the Speedball 's product page on Amazon and used the chart. I should have bought the one with stand because oneday I hung the light over the screen and a glass cover, then the light slipped and dropped on the glass, broke the glass! I hung the light using the product "Cell phone clip holder clamp mount flexible 360 degree rotation, long arm bracket for 3.5-6.5" phones" I thought I could use that cell phone holder with arm for hanging this light. But not secure. Anyway the light works, see the photos of my screen and print.

Extremely well priced. It's not the most amazing build quality, but I don't think you need it to be if you're just exposing some screens casually as a DIY screen printer. It exposed at 16"x16" design at 12" away for 12 seconds and the art turned out great. I could have used even less time for the exposure. Saves a lot of time over a BBA Photoflood incandescent bulb. This is a great upgrade.

The light works well. The structure of the light is flimsy and very hard to keep an angle.

Burns my screens perfectly and easy to set up

El material es muy bueno, la luz es lo suficientemente potente. Lo recomiendo. Lo usare para serigrafía espero subir actualización del proceso

I realize this unit was inexpensive and advertised as easy to assemble; however, as no instructions were included. I cannot see how the light is attached to the unit. It appears it should just snap into the holder; the so-called holder does not secure the light. Very frustrating. I am a couple days past the return date; I tried to contact the vender- no response. I will call Amazon and see if they might accept a return.

De muy buena calidad

Flimsy and hard to aim properly.

The stand and assembly is super flimsy, but for the price I was ok with it. But then today, maybe the 7th time using it, it stopped working and no longer turns on. It has been less than a month and I am returning it. I'll be looking for another product.

entrega antes de lo prometido, excelente vendedor

la verdad compre el articulo e hice barios intentos para revelar un marco y no logro catalizar la emulsión incluso de cerca le llegue a dar 20 min con las lamparas y la emulsión se caía muy fácil
