Candles not blocking walking through them

Would be nice if candles had no collision box (like torches). Most lightsources have collision box. Those are just full blocks, end rods, campfire or lanterns. When you want non-colliding light, you are limited to torches (soul torches, redstone torches), that need supporting block. Only normal torch is bright enough to prevent mobs from spawning without spamming those too close.

Disabling collision box for candles would make them great light source - any color you want and can be placed (keeped) mid air.
