Just a heads up to everyone (if you're ordering from US Amazon). There are few variations of the A4 out there. The A4 I ordered was $69 and was stated to be the "BRIGHTEST" of the 17.7 line. 4800 Lux. I figured, brighter is better. But my only caveat is that it doesnt come with a MicroUSB plug like the other two versions, the LS4 and the LB4. It comes with a DC12V charger that is very short
Also for whatever reason Huoin has two different listings for these lightpads on amazon, and on the two different listings prices vary by a few dollars and it looks like "what's included" varies depending on which amazon listing you choose.
I have a kindle cable that I was planning to use with it thats 5feet long, but alas no MicroUSB on the A4 version.
Basically the 17.7 Huion Lightpad lines rolls out as follows:
The A4 Model $69
Brightness of 4800 Lux (The Brightest)
DC12V Charger that doesnt have a very long cable
The L4S-$42
-Brightness of 1100 Lux
-Micro USB Charger (No wall adapter)
-Comes with some 5 sheets of tracing paper, and a Recycling Non-woven Bag.
The LB4$84
-Brightness of 1500 Lux
-Micro USB Charger w/ wall Adapter
-*RECHARGEABLE* So you can charge it and it will hold a charge for 1.5 hours. Nice portability option.
-2 little Rubber ball stands to prop up the light pad at a slant.
-10 sheets of tracing paper, and a Recycling Non-woven Bag
So I guess there are pros and cons to each. The $84 LB4 sounds like the best deal since it comes with extra goodies and its rechargable. But the $69 A4 Lightpad is
3 times as bright but you just might have to order a longer adapter. I'll see how "Bright" this A4 is when I get home and let you know.
Hopes this helps anyone that was a little confused by all the variations like I was.
