I put up a very bright LED work light (suspended) over my quilting machine / frame. It was not expensive and was from Home Depot. I prefer using the sun, however living in Oregon sometimes precludes that method. I discovered that the bright light over my quilting frame works very well. I don't believe a "box" is a useful investment, as it is easy to place the screen to be exposed with the image and glass on a black piece of felt in a box lid (like a paper or bankers box for portability) and with a piece of thick cardboard "lid" or cover to protect it from light except when exposing. I place the box lid / exposure "sandwich" on the quilt or whatever I happen to have mounted on the quilting frame (a table would do) and sometimes elevate it a little more with a portable footstool or box. With my iphone timer running, I uncover the glass/emulsion/black felt sandwich for the needed time, then quickly re-cover it with the cardboard sheet, then pick up the whole thing and take it to the kitchen to rinse. It works great and is very affordable.

I'm using a cheap growllight for a certain emulsion and it works perfectly. It also shortens expo time compared to my old expo unit with fluorescent on it.

That’s great! DIY setups definitely can work when the proper testing is done 👍🏼

so is a metal hallide bulb out of something like a Douthit exposure unit compatible with Chrmoalime. What type of emulsion is Chromalime, we just switched to it

Chromaline is a pure photopolymer emulsion designed for humidity resistance and plastisol ink. Yes you can use the Douthitt unit to expose. Just do an exposure test to find out your exposure time 👍🏼

led es la mejor opción

As long as it is in the correct wavelength!

@@chromalinescreenprintproducts es correcto, hoy en día el led uv se puede fabricar en la longitud de onda que necesitemos @chromalinescreenprintproducts is correct, today UV LED can be manufactured in the wavelength we need

you made a whole list of lights that wont work.. but didnt name a damn thing that IS good to use.

Many of the ones mentioned will work, it just depends on what wavelength the light source is and what emulsion you are exposing. If you want a specific light source, we recommend the Quick Image exposure table top unit, or the LTS laser-to-screen auto exposure for larger shops.

So spend $800 is your answer..NOT
