I am on a server (Timeless PVP Factions) with blaze spawners able to be harvested, and I have made a blaze farm; however, my lighting isn't working to turn off the spawners. Usually light will work, but when the lights are on, blazes are still spawning. See this picture:

As you can see, the blaze in the screenshot just spawned even though there are MANY lights on. What can I do to make sure that these spawners are deactivated when lights turn on?

Although most hostile mobs require 7 light or less, blazes are special in that they only need 11 or less. This means that, from the light block, you need 2 or less spaces of air between any space where a blaze can spawn. It appears that your light spacing does not take that into account.
