And he said LED there be light!
These are the strips that inspired to the Solstrip, they only have the LM561B chips and not the LM651C chips.
I have yet to find anyone selling LM651C strips in Europe, but again these cost next to nothing compared to SolStrips.
I payer 10$ pr strip incl drivers, at Estonia export (ebay) = 650$ incl shipping and no import.
Compared to SOLSTIX X2 at 29.90$ + shipping and import tax. That's 1943,5$ for 65 strips, lets say shipping is free. 25% Import tax, would come out to 485,87$. So all in all just around 2430$ total + drivers.
The TCI strips give out less lumens, but I still got almost 1800$ in the budget to hang a extra LED strip in each cab. And run them for many many years, before I would have spend that.
That been said, it would have been fun to try the LM651C SolStrips next to these.
