The Best LED Grow Lights for Houseplants This Winter (2026)

Summer is officially over, along with its allotment of free sunlight. You might be sad about this, but your indoor plants might be even sadder. A good LED grow light can replicate sunlight with full-spectrum light and day/night cycles, keeping plants lush and thriving even in a dark, windowless corner or basement.

夏天正式结束了，随之而去的是免费的阳光。你可能会为此感到难过，但你的室内植物可能更难过。一款优质的 LED 植物生长灯可以通过全光谱光照和昼夜循环来模拟阳光，即使在黑暗、没有窗户的角落或地下室，也能让植物保持茂盛生长。

I have no fewer than 40 houseplants in my home at any given time, as well as a fair number of grow lights, and what I’ve found to be important for a general consumer (i.e., someone not doing that kind of indoor grow) isn’t necessarily certain colored light wavelengths but whether a grow light is easy to live with in your house.

我家里随时都有不少于 40 盆室内植物，同时也拥有相当数量的生长灯。我发现对于普通消费者（即那些并非进行专业室内种植的人）来说，重要的并非某种特定的光波长，而是这款生长灯是否能让你在家中轻松使用。

Many grow lights are more or less going to serve the same purpose, so what you really need to know is this: Is the light so bright that it’s disruptive? Does it require complicated installation? Is it easy for kids or pets to knock over? The grow lights recommended below are ones that WIRED staffers have lived with for months, if not years, and have found them both effective and easy to integrate into our lives.

许多生长灯的功能大同小异，所以你真正需要了解的是：灯光是否太亮而造成干扰？安装是否复杂？孩子或宠物是否容易将其碰倒？以下推荐的生长灯都是《连线》（WIRED）员工使用过数月甚至数年的产品，我们发现它们既有效又容易融入日常生活。

What Is PPFD?

什么是 PPFD？

Photosynthetic photon flux density, or PPFD, expressed in micromoles per square meter per second (μmol/m²/s), is a measurement of how much light reaches your plant that’s usable for photosynthesis. In general, the higher the plant’s energy needs, such as producing a flower or a fruit, the higher the PPFD number you want. Though different lights have different height requirements given the plants they’re made for, for standardization purposes, I measured the PPFD of each grow light at 18 inches with the Photone app and a light diffuser. Keep in mind these measurements are general and approximate.

光合光子通量密度（PPFD），以微摩尔每平方米每秒（μmol/m²/s）为单位，是衡量到达植物且可用于光合作用的光照量的指标。通常情况下，植物的能量需求越高（例如开花或结果），你所需要的 PPFD 数值就越高。虽然不同的灯具根据其适用的植物有不同的高度要求，但为了标准化，我使用 Photone 应用程序和光扩散器在 18 英寸处测量了每种生长灯的 PPFD。请记住，这些测量结果是通用的近似值。

How I Test Grow Lights

我是如何测试生长灯的

Some of these grow lights I bought myself, with my own money, before I even began working at WIRED. Others were owned by staffers and recommended to me. I also have press samples from other guides I worked on, which I liked so much I ended up keeping around.

其中一些生长灯是我在加入《连线》之前自费购买的。另一些则是员工自有的并推荐给我的。我还有一些来自我参与制作的其他指南的媒体样品，因为非常喜欢，最终留了下来。

For the traditional grow lights, I tested them at home under normal-life conditions. I put them where they’d fit, tested their timers, and noted whether or not they were dimmable. I also measured each light’s PPFD (see above) and noted whether certain lights could be daisy-chained for more extensive coverage.

对于传统的生长灯，我在家中正常的居住条件下进行了测试。我将它们放置在合适的位置，测试了定时器，并记录了它们是否可调光。我还测量了每盏灯的 PPFD（见上文），并记录了某些灯具是否可以串联以实现更广泛的覆盖。
