I thought this wouldn't fulfill your 'low profile' requirement until I saw the Origin 8 Vivid Pro you've ordered. Anyway, it doesn't cost anywhere near $50 and it puts out way more that 250-300 lumens, so perhaps you wouldn't have liked it anyway. Uh, the slow flash - and it is quite slow - is in the S-O-S pattern. Shrugs - nobody has offered to come to my aid yet.
