Bought a pack of 4x LEDs (Luminus A60 brand, type B22, 9 watts, 806 lumens, 5000k, dimmable) at average $3.25 each. Bunnings has a similar looking one for $3.00 each (Click A60 brand, type B22, 10 watts, 800 lumens, 6500k, non-dimmable). By my reckoning Luminus's efficiency is 89.5 lumens/watt and Click is 88.9 lumens/watt. But Click gives out 1500 more kelvins than Luminus. Ignoring dimmable, which one is better bang for buck?

I had Bunnings click leds. Hasn’t lasted over two years. Only have 4/25 left I think. Replaced 21/25 with the ones from Costco
Just FYI, in this context Kelvin represents color temperature, so I think your statement about one giving out more kelvins doesn't really make sense. 6500K would be bluer than the 5000K
I am just reading off the specs.
I've had 10 of the Costco Luminus LED bulbs, I've just past the first year and they're all going strong.
The number attached to the K just describes how warm yellow or cool blue the light will be, doesn't have anything to do with power.You need to be looking at the Watts for power consumption and the Lumens which is how much light it will emit, in this case it's 806 vs 800 which is roughly the same.
Based on numbers, I would recommend the Costco Luminus ones because there's slightly less power consumption for more light emitted, but it depends what colour light you want.
Also Costco have the lifetime satisfaction guarantee so if you're not happy with it you can return itAwesome thanks to all who commented.
The Luminus is better the higher CRI and warmer tint is harder to drive so you don't get the same efficiencies but seeing as the efficiency is similiar you can tell the Luminus is a better diode.
Plus 5000k is a better tint compared to 6500k but its still a tad cold for most.
Plus if the bulbs are made by Luminus them selves they are a massive LED manufacturer the quality will be better. Cree was making bulbs but dropped the line.
