not good with variations in led vf and drop due to length.
the ones closest to the feed will be overdriven.
the resistors relieve this.

Meh, bypass the resistors with solder blobs and use a real driver for the lengths you cut yourself.

SKV89,

 

I took the liberty of putting your data in a spreadsheet (google sheet).

 

High CRI LED light strips (and a few bulbs)

 

Maybe you can add the link to your OP?

 

If you want to be an owner of the spreadsheet to make edits, PM me.

There is also a spreadsheet of SKV89’s stuff in the OP here: http://budgetlightforum.com/node/69967

I saw the inclusion of SOME SKV89 data in this spreadsheet:

https://docs.google.com/spreadsheets/d/12jj1A6PNjHmWbFNu0FSisEztir7izxAh...

from this thread:

http://budgetlightforum.com/node/69805

compiled by fneuf.

But it seemed that fneuf only included measurements that included R12 data (it factors into his “grading” formula) so most of the SKV89’s data is not included. (R12 was measured for only 3 out of 34 products)

CRI_Grade was created by me, I added it to his spreadsheet for him. It uses Ra, R9, and R12. It really targets the weak areas of modern LED technology works stellar. There is a link in my signature about it.

Never caused me any problems, but i do tend to underdrive them.
YMMV, as they say.
