Why do Stela lanterns fail so early? « on: March 18, 2025, 03:44:46 AM » Author: Eleco_SR304
For some reason, I've haven't really have a chance to see many Stela lanterns but from what I've seen, many after a couple of years have a couple of LEDs dead and some LEDs which almost give no output. What's the main reason for this? Are the LEDs all separate or is the panel (Aluminium PCB) that get's rusty in some places (or the LEDs are just rubbish so they just die)? I would like to know the answer to this. If someone owns one, they will definitely know the answer to the "Are the LEDs separate or all together" question.

More now interested in Polish Street lighting, the country where I come from.

LED fixtures need to stop replacing fine-working streetlights. However, I except retrofits, only if it's done very well.

For today I live in England, so except me posting English fixtures as well.

All from me, 220v-240v

Stelas are early led lanterns (2008-2009), many lanterns from this era had similar reliability, the stela was just one of the first widespread led lanterns in the UK (meanin gthat it  may seem like more fail). I would bet that if you looked at 5 stelas and 5 of a different brand led lantern from the same era in a simmilar installation, their condition would be similar. Also I think that the stela has poorer quality, SINGLE diodes (this is just a guess though).

Always thought the Advanced LEDs Marlin was first as they date from 5th January 2010
