In a fluorescent lamp, the emitted light is in the visible spectrum - the phosphor gives off white light we can see. This photon has less energy than the original photon, because some energy was lost as heat. When the electron falls back to its normal level, it releases energy in the form of another photon. When a photon hits a phosphor atom, one of the phosphor's electrons jumps to a higher energy level, causing the atom to vibrate and create heat. Phosphors are substances that give off light - or fluoresce - when they are exposed to light. They do this with a phosphor coating around the outside of the tube. UV light waves are too short for us to see - they are completely invisible - so fluorescent lamps have to convert this energy into visible light. They emit some visible light photons, but mostly they emit photons in the ultraviolet (UV) wavelength range. When energized, mercury atoms emit energy in the form of light photons. Fluorescent blacklight lamps generate light by passing electricity through a tube filled with inert gas and a small amount of mercury. Philips also sells the Gradient Signe in a table lamp version.How a Black Light Works: The conventional black light design is just a fluorescent black light lamp with a couple of important modifications.
The floor lamp comes in black, white, and oak/white. We also didn’t like that it doesn’t have a physical on/off button, so you can only turn it on or off with the app. At around $330, it’s not a cheap lamp and we thought the plastic finishes on the rod and base could look better for that price.
You can choose any color and brightness or even a combination of up to 3 different colors to create your own gradient effect, which we have to admit looks pretty stunning.

The lamp can be controlled via Bluetooth but like their smart bulbs, we think it works best when you combine it with their Hue bridge (you get better range and more features). Like the Felix Lamp, rod floor lamps work best to brighten up a dark corner or to illuminate a wall, but because the Gradient Signe’s light can be endlessly customized, we think it’s more adaptable than your average rod lamp-especially if you’ve already bought into the Philips Hue ecosystem. If you want a rod-style lamp with smart features: The Philips Hue Gradient Signe Floor Lamp is a rod floor lamp that comes with all the benefits of a smart bulb, but in a bright LED rod format that can brighten up a big space. If you’re a Netflix binger, you’ll want a lamp delivering a diffused softer light without glare intruding on “just one more episode” evenings. If you knit or read often, a light delivered from overhead or from over the shoulder is best. Consider your most common nightly habits. A rod-style lamp won’t light up an entire room, but when placed in a corner will deliver supplementary light that enhances every other light source. Lamps fitted with shades, which we refer to as console lamps (also known as “traditional” or “shaded”), diffuse light to a pleasant ambient glow around and overhead, but they aren’t the best for reading. A tree floor lamp offers adjustable light, but its reach is inherently limited by the positioning of its multitiered shades. Do you want to read or work underneath the light, or is the lamp primarily intended as an ambient source? Task and arc floor lamps are best for delivering glare-free light from overhead, ideally with cantilever swing arms and/or adjustable shades to direct light exactly where it’s wanted.
