Hi Keat,
Really sorry about the different colour output, this would be an issue with batches, on the back of the light there will be a batch number can you find the good batch number you want and email it to us at returns@thelightingoutlet.com.au and we can send it out so they are all matching correctly. For each batch of LED's are very hard to get exactly the same. The person who picked this order should have known this I'm sorry about that.
