True, as long as you can sell them for more than £24, which should be possible
Then you sell the extra on eBay which makes the bulbs work out even cheaper
What if you only need 2?
Hue system is great however these bulbs are not. These are not the richer colour version so the blues and greens are really bad.Also be careful you have enough room in the ceiling as these bulbs are much longer than what you would be replacing them with and might not fit!
