It does allow color to show in the day, however it has no diffusion whatsoever. They are see through. I tool some sand paper to one and it gave ot a frosted look that helped tremendously to diffuse and make it look great
Saber Guild member here. These day blades are amazing for day time, bright sun combat, showing brilliant color even if the saber is not on. They are also wonderfully strong and sturdy, taking a beating and surviving like champs. Absolutely love the fact the tip is threaded which makes losing it very difficult, especially with more violent combat. Will be purchasing more in the future for myself and my temple members!
The blade looks and fits awesome. The only issue is if you plan to use it in the dark with the saber light you'll need to get diffuser film. This blade did not come with it.
They work ok. It definitely lets you see the color better in strong light. However the sides of the blade don't diffuse the light like the normal blades do, instead it all shines out the tip end like a flashlight on and doesn't give the impression the whole blade is glowing. If you leave the lighted area I think they look significantly worse than the standard blade. Almost better to just turn the light off and rely on plastic color alone.
I opted to use the Kyber Light dayblade since a lot of the photos were going to be taken outside, and I think you can see the difference it made. Well, you would be able to see if I was allowed to add photos...which I thought was kind of the point. I'll add pics in later if I get permissions.
