Inside a Philips light from LIDL.
Added 2020-02-07 02:49:18 +0000 UTCLIDL is a stack-'em-high low cost supermarket chain that uses short weekly bursts of gadget stock to keep people coming back. Obviously I had to go and check out what they had while I was visiting Glasgow.
This light is very similar to the generic import units, but claims a 15 year LED lifespan and promises that you'll never have to change a lamp again. It's true. You'll have to change the whole fitting instead.

I picked that up, felt the weight of the glass and then put it back because I was travelling.

2020-02-20 03:09:38 +0000 UTCThe most common issue for sudden dimming is a failed LED that tracks over internally until the circuit is such a high resistance that it barely glows. Usually manifesting as one or more LEDs with black dots in them where they burned.

2020-02-20 03:08:48 +0000 UTCI've a philips ES LED bulb here which has been used (outdoors) near continuously for less than a year. I changed it this month because, in about the last month or so it had become very dim. I've not yet opened it up to take a look, but am curious as to what might have gone wrong.

2020-02-10 18:02:50 +0000 UTCThe Irish Lidl got in a different motion sensor ceiling light, their own brand Livarno Lux priced at €20. The light looks almost identical but without a visible PIR shown, so probably microwave based. Going by the specs on the box (I took a photo), its runtime is adjustable from 5s to 30m, adjustable range sensitivity up to 15m and includes a 10W LED rated at 806 lm. It says the max permitted bulb power is 20W, indicating it's replaceable.

2020-02-07 05:32:45 +0000 UTCSo refreshing when companies tell a part-truth; even a half-truth is becoming rare these days. And never having to change a bulb may prevent "electrician's wrist"–a double benefit!
2020-02-07 05:00:42 +0000 UTCWe had a LIDL move in less than a year ago 5 min. from my house. I stop in from to time to time to see what kind of stuff they have. I have purchased a variety of stuff from them. Decent prices and quality is usually ok. I got a string of color changing LEDs with a remote that the wife uses to provide accent light on some of her decorations.

2020-02-07 04:04:34 +0000 UTCYes indeed WELL worth taking to bits! It's funny how all the extra guarding looks like it is a little much
