A while back I was looking for a desk / bedroom LED lamp that has touch sensitive controls, a composite light system (rear and down facing LED banks), no PWM, and good neutral/warm tint with flexible arm. The Xiaomi Philips Smart Lamp (v2) turned out to be it. While the tint was a bit leaning cool from neutral, I solved that with optical adhesive affixed filter sheet trimmed to fit. The lamp also came with a WiFi enabled communication module where a phone app would be able to control it. That didn’t work, because of issues with specifying the USA region. I couldn’t even do it specifying China. But this wasn’t an important feature for me. Anyway, 4 years later and the lamp still works great. There is no problem with ramping or brightness order, as there are direct access touch controls easily tapped.
I’ve been looking for a second, smaller LED lamp that would cost about half as much or less, and possibly have the precise specs I want:
- CCT of 4000k ~ 5000k. If more than one tint, this would be the FIRST tint that comes on by default, or there’d be a way to lock it in to one specific tint – either memory, or a fixed configuration.
- Mode memory that remembers the last intensity and tint used, AND will retain that even if unplugged for a few hours.
- If there’s a built-in battery for cordless use, you can turn off the battery and have the light come on when plugged in only.
- Ramping should be smooth and at a moderate pace (not too fast or too slow)
- Top end brightness doesn’t need to be super powerful – the other features are a priority.
- Wish list: mechanical switch such that the light can be controlled from a wall switch contrlled power socket.
From all I’ve seen, it appears like most of these new LED lamps don’t have mechanical switches. They’re all touch sensitive or tactile electronic. This means you can’t have the light switched on and then control on/off from a wall switch. Rather annoying.
I bought 3 different desk LED lights recently. Two of them have built-in batteries and one doesn’t. All of them have multiple CCT modes and brightness modes.
The other REALLY ANNOYING PROBLEM I encountered, is that none of them start on the warm CCT. It’s either neutral or cold. One of them requires you to tap 3 times to get to warm. So there’s no single mode ON/OFF functionality with the switch. You must go through each tint.
The ones with batteries cannot run directly off of A/C and leave the battery alone. If you do have them plugged in, they use the battery and then the battery is simultaneously charged. There is a tiny black physical switch in the back of one that appears to function as a lockout. The soft-touch control becomes inoperable. But sadly, this also disconnects all power to the lamp and thus it loses memory. And that means you have to reset it for each CCT mode.
In terms of brightness, some of them are stepped and some smooth ramping. However, one ramps smoothly too fast and the other a bit too slow.
So…
Anyone here found a nice LED desk lamp that meets the spec requirements I’ve listed above?
