Carrying on from Ukastle 2, what are the design faults that lanterns have? A few from me to start this off.
Revo Sol D'or - Bowl toggles seize (stainless steel in an ally housing - the WORST 2 materials for electrolytic corrosion) meaning bowl can't be removed or toggles are left in the open position. Grub screws in top of "shoe" leading to corrosion as rain gets in.
Revo Horizon - Grubs screws on top of canopy - like Sol D'or.
Thorn Alpha 1 - Opticell splits along manufacturing seam as glue could not cope with UV and British weather.
Thorn Alpha 8 - bowl toggle goes brittle and snaps.
Thorn Beta 5 - Plastic clip models tend to fill up with water...
Thorn Alpha 5 and Beta 8 - Tend to lose bowls over time.
GEC 9554 - Glue used to secure refractor panels eventually eats through bowl, causing it to fall apart.
Urbis Sapphire - Looses canopy
Philips Iridium - Looses canopy
Philips SGS306 large Traffic Vision - Plastic gear tray melts (several spotted like this at a depot). Lantern rotates on bracket when side mounted and turns upside down.
Urbis ZX3 - canopy securing clips fall out when canopy is opened resulting in lost canopy.
Urbis ZX1 - Canopy becomes loose (don't know how as some models have thumb screws and clips..)
Phosco P152/P153/P157 - bowl securing toggle falls out when bowl is opened.
Revo Prefect - Lamp holder wing nuts made from zinc and break.
Thorn Gamma 5 - Later models have canopy securing screws - sealing washer perishes and screw seizes, water gets into bowl.
GEC "large saucer" - Canopy becomes detached, lantern turns into large bird bath..
