Well, i guess we missed a price increase some place

These were $6.30/meter 2 weeks ago, now they are $7.20/meter. Still better than the $10.50/meter for tm1809's
These are 5v strips , individually addressable. I am making a 30 high by 5' long panel. I will use it as my tune to sign and also show the current playing song. I plan on using one falcon-16 each string driving 100 pixel nodes. I dont think i will need power injection.
I will get 10 flex strips

Each 5m strip, i will divide into 3 pieces.

For my arches i will be using the 12v flex ws2811, this is the one that is in groups of 3.
at $6/meter it is the cheapest lights you can buy.
I will be getting 20 or so of these.

The flex strips Jon and I used at the academy were the 12v , 4m 1809
$10.50/meter

ok... 5v, that's why I couldn't find the 12v, ws2811, with resolution=1.

at this point I'm still looking at TM1809 12v then...  since i'm stuck in a rut, I plan to stay with 12v, and lights which can be used with both falcon and lynx solutions.

i'm looking at the other supplier with double-wall, 16mm cell height -- so I hope it will all come together.

thanks!!

16mm cell height - sounds good since Pixel spacing is 33mm on the strips (30 pixels per meter). Every other row would be very good spacing.
