UV glow- with blue & silver glitter (glows blue).
Grub measures 2" in total length.
UV glow= 15+ minutes (Orange) to 12+ hours (green) as manufacturer states. After testing these out, the aqua seems to have the most steady glow, green does burn the longest and although dark blue lasts long, it's sometimes hard to tell because it's dark.
It is recommended to use a UV light on all UV glow products to speed up glow process.
