That link says they only have the 5000K in stock and they are $9.94 plus shipping which makes them more than twice the price of the Bridgelux version from Cutter $4.37. https://www.cutter.com.au/products.php?cat=EB+Series
The Samsung data sheet doesn't tell you the output when you drive them more than 240mA.
The Samsung specs claim 10% more lumens per watt, which sounds good but in reality it means a savings of only 4cents/mth. in electricity per strip, meaning it's going to take about 10 years to claw back the price difference.
But you change your strips every 3 or 4 years because the LEDs wear and loose output, that's why I never use a constant current source, must adjust current as they wear using light meter.
More importantly you only need 4 x Bridgelux strips per sq. ft to get around 5,000 lumens per sq. ft., but you need 5 x Samsung strips to get the same. That equates to 4 x $4.37 = $17.48 vs 5 x $9.94 = $49.7 per sq. ft.
