"for £6 youre not going to get this kind of quality anywhere else Its LAP branded,the whole casing is galvanised steel & the cover itself is pretty much unbreakable 1/4 inch thick plastic. Looks wise its not going to win any awards but thats pretty obvious but it is small,neat & well made.
paired with one of the 20w sylvania spirals http://www.screwfix.com/p/sylvania-spiral-cfl-es-20w/24732 (short bulbs are needed in this,a standard low energy bulb wont fit) it throws a good amount of light out after the 20 second warmup period,"
"Have just updated 40 year old bulkheads with 30 of these for communal areas in blocks of flats. Have added dusk-to-dawn sensors and the lighting is exceptional even when fitted with 7W bulbs. Much safer environment in stairwells and low electricity consumption. Brilliant value."
"These are amazing value for the money and so long as you can have your conduit or cable lining up exactly with the cable entry hole, these will be perfect. It's a very sturdy, cast alloy lamp and the seal between the two sections is great. However, if you need a bulkhead light that can accommodate a junction or can take a side entry, this isn't the one. Even if you drill an entry hole, the moulding does not allow a cable to pass between the void of the mould and the cable entry hole."
