Three GRIFEMA products appear here. On the European stores all three sit at the bottom of their families on price; on Amazon US the two key safes are listed far higher, around $44, and the floodlight is not listed at all.
The key safes
The GA1003 and GA1004 are 227 g (8 oz) and 558 g (19.7 oz) of zinc alloy respectively, with four-digit codes. That is not a safe and this site does not describe them as one — they resist a curious hand and a screwdriver, and they exist so that a key need not be handed out.
Where they go matters far more than what they are made of: out of sight of the street and not beside the door they open. The GA1003 screws to the wall, and belongs in masonry rather than stucco or siding; the GA1004 hangs from a shackle, and leaves with the box if someone cuts or lifts it.
The floodlight
The GD402-2 has three separate adjustments — sensitivity, on-time and the ambient light threshold below which it will trigger at all. That third dial is the one people leave wrong, and a light triggering in daylight is a light that wears out and annoys the household.
At 2200 lm and 6500 K it is bright and harsh. The color is what neighbors complain about, and a light that gets disconnected after complaints protects nothing.
What none of the three publishes
Any security grade or resistance certification. The floodlight states its lumens, IP66 and a 2 to 12 m (7 to 39 ft) detection range; the boxes, ten thousand combinations. Read them as what they are.
