Christmas Lights: Why does an entire string of lights that worked last year not work?

Thu, 19 Feb 2026 05:31:27 -0700

Three sets of lights were working just fine last year. I plugged them in this year, and all three strings were dead. Why?

The base weight of my Kendal Three Lamp floor lamp is falling apart. It appears to be concrete wrapped in plastic. It is making the lamp unstable. Can the weight be replaced? Where to buy one? Can I do it?

Flashlight: Tactical flashlight won't work with new batteries. Emitter, driver?

Tue, 03 Feb 2026 13:13:15 -0700

I have four Pro-4 tactical flashlights (two large, two small) that worked well for at least five years. Now they're dead and new batteries aren't the fix. Interiorly, in each, it's clear the emitter is (securely) wired to a driver. How do I determine what component has failed? Are the components replaceable? These flashlight are heavy, milled aluminum worth much more than their original ticket...it seems unthinkable to toss them.

I might add that, sadly, the small emitters weren't designed for easy replacement as they appear to be a permanent part of of a design-specific aluminum ring.

How might I proceed? Happy to provide flashlight ID, disassembly, and repair pics when/if pertinent. I can do basic soldering and my fixit persistence is a local legend.

I found the Pro-4 flashlights at Sam's back in the day. One can find them used on eBay, but it appears they're no longer manufactured. The original promotional copy included:

The Pro-4 Tactical Flashlight with COB Lantern is up to 40 times brighter than ordinary flashlights. It features, aircraft-grade aluminum construction, zoom-in and zoom-out functionality, and five light modes. It provides bright, reliable light in nearly any situation. Use for home, work, outdoors, and emergencies. The Pro-4 Tactical Flashlight with COB Lantern is one of the most powerful flashlights of its size on the market.

LED Christmas Lights: 1000 light deer not working but the line has power

Mon, 12 Jan 2026 14:18:27 -0700

We have a 5 foot deer with at least 1000 LED lights that stopped working. The transformer is putting out 24.2 volts - supposed to be 24. The deer has 2 connectors inside, probably splitting the line into thirds. If I disconnect either one, there are 24.2 volts coming out of each. The bulbs are sealed - not able to be unplugged or taken out. Why would the lights not be on?

Philips Wake-Up HF3520: Light doesn't stay on when clock reaches actual alarm time

Fri, 26 Dec 2025 00:26:03 -0700

My clock has an issue where the light comes on during the build-up to the alarm, but turns off once the clock hits the actual alarm time (but demo mode works perfectly). It usually would keep the light on for about 90 minutes after the alarm time unless turned off, but it stays off during this time as well. What’s strange is that the clock display is brighter, like the clock knows the alarm is happening, but the actual wake-up light is not on. Sometimes, unplugging the clock for a few minutes and plugging back in can fix this for a few days, but other times that doesn’t work. It’s very frustrating and has made the alarm completely unreliable.

Also, occasionally I get the random clicking sound like it thinks the buttons are being pressed when they’re not, as mentioned in a question by another user. I’m not sure if these are related or not.

As stated, I’ve tried unplugging and plugging back in, I’ve also tried unplugging and holding down the light on/off button for 15 seconds as suggested in another comment. But regardless, the issue eventually comes up again. Any help is appreciated!

Artemide Tolomeo: The head of my Micro model is flimsy

Sun, 12 Oct 2025 02:09:45 -0700

Hello,

We bought the Micro model for our bedside stand, and only after a while realized that the flimsiness in the top joint (where the bulb sits) is not supposed to be that extreme. :D

We literally cannot set it any way, it always falls down.

Would anyone know how to tighten that joint?

I removed the 2 small black caps on the sides, in hopes there would be a screw or two for the springs, but no luck there.

Thanks!

T8 Fluorescent Fixture: LED bulbs have started flickering and turning extremely dim instantly

Sat, 27 Sep 2025 09:30:04 -0700

We have a T8 fixture over our kitchen sink. We have been using LED bulbs compatible with T8 for years, They generally last nearly a year before needing to be replaced, but the most recent one started flickering after only a few months of use and went out completely a week ago. Since then we have replaced that bulb with two others, both of which started flickering almost immediately, and then after about a minute went exceptionally dim. This change is accompanied by a strong chemical odor (I'm assuming it's something happening to the phosporous inside the light).

Is this a common issue that is fairly easy to diagnose and fix on my own or will I need an actual professional to look into it?

Philips Wake-Up HF3520: device "clicking" quickly like proximity sensor feels something

Mon, 01 Sep 2025 01:42:30 -0700

Philips HF3520/01 Wake-Up Light - suddenly starts making never-ending quick “clicking“ sounds, speeding up.. This is normally sound of proximity (touch) sensor.. but there is nothing close to device, and it is clean…. It is unstoppable, only it stops if disconnected from power… After connecting it can work for hours correctly, but problem appears later again…
