Cobra XTralite Filter Type_Colour and it is a strapThe Cobra XTRalite is a compact remote flash unit that provides a touch of extra lighting without wires: it uses a light sensor that triggers when your main flash goes off. Not power adjustable, but definitely powerful enough (still got eyeball spots). Runs on one AA battery (sold separately) but be aware that the battery chamber is pretty tight, so you'll have better luck with non rechargeable batteries.
