Would the light be strong enough to go through a 300 lb watercolor paper?

If I close the drapes to make the room dark , I can trace through 300 lb paper . (At least enough to see the basic shapes,and then some ( 140 is perfectly clear )

Does this come with the power adapter or do we need to order separately?

It does not come with a power adapter...you don't need one. It plugs directly into any electric outlet.

is the power supply cord with adaptor included with light pad

Yes and this Light pad is wonderful. Love it.

how many led diodes and lumens, please? There is no factual info posted about the amount of light- important to know when buying a light?

This lightbox is mainly intended for art/crafts activity. People familiar with art lightboxes are very impressed with its bright even light and quality. If you are a photographer you want color correct lighting. This is LED technology, a relatively inexpensive alternative producing brighter light given the power consumption. Lumens is not mentioned on the Artograph website. Reading every comment it is very bright and even lighting. It is well-built and Artograph even drove a car over one 6x and threw it off a 2-story bldg. "Super Bright LED lamps provide a perfect, evenly illuminated surface. Maintenance free LED lamps last up to 50,000 hours = 4 hours a day x 35 years."~Artograph. See YT Video: "Artograph LED LightPads" a Blick video.
