FAQ
The recessed light, the way it used to be. A frosted BR30 incandescent that gives 600 lumens of warm, full-spectrum light from a real tungsten filament. Our spectrum report measured a CRI of 99.2 with no blue spike anywhere in the curve. It screws into standard recessed cans and dims smoothly on any dimmer.
We measured this bulb's light from 380 to 800 nanometers, which covers every color the eye can see. The result is one smooth, unbroken curve. Every color is present, and the light rises steadily from blue into deep red with no spikes and no gaps. Here is what each number on the report means.
CRI 99.2. CRI stands for Color Rendering Index. It scores, from 0 to 100, how true colors look under a light compared with natural light. 100 is a perfect match. Most LED bulbs are rated 80 to 90.
R9 of 97. R9 is the score for deep red, which the standard CRI number leaves out. Red is what makes skin, food and wood look alive. Many LEDs score low here.
Fidelity 99. A newer and stricter test than CRI, listed on the report as TM-30 Rf. It checks 99 colors instead of 8 and scores how accurate they look, out of 100.
Gamut 99. Gamut, listed as TM-30 Rg, measures how vivid colors look. 100 is natural. Lower looks dull and washed out, higher looks artificially saturated. At 99, colors look the way they should.
2611K color temperature. Kelvin (K) describes how warm or cool a white light looks. The lower the number, the warmer the light. 2611K is a warm, golden white. Bright white LEDs are usually 4000K to 5000K.
Duv 0.0009. Duv measures tint. Zero means a clean white with no green or pink cast. This bulb is almost exactly zero.
A white LED starts as a blue diode. A phosphor coating turns part of that blue into the other colors, but a sharp peak near 450 nanometers remains, usually followed by a dip in the cyan range. The whiter the LED, the taller that peak tends to be.
Blue is the part of the spectrum your body reads as daytime. Research links blue-heavy light in the evening to lower melatonin and later sleep, and many people find it harsher and more tiring to sit under.
This bulb has no blue spike at all. Blue is the lowest part of its curve. The report also lists a melanopic ratio, which measures how strongly a light sends that daytime signal, with daylight scored as 1. This bulb measures 0.44, less than half.
The glass has a soft white frosted finish. Instead of a bare filament throwing a hard beam, the whole face of the bulb glows and spreads the light wide and evenly across the room.
The result is soft light with gentle shadows and no harsh glare when you look up. It gives a room an incredible atmosphere.
It is real glass. Most LED recessed bulbs use a plastic cover.
There is no driver, chip or power supply inside. Wall power heats the tungsten filament directly, and a glowing filament cannot switch on and off the way a diode can, so the light stays steady with no visible flicker.
It dims beautifully on any standard dimmer, with no compatibility list to check.
BR30 is the standard size for 5 inch and 6 inch recessed cans. The bulb is 3.75 inches across and uses a regular E26 screw base, the same base as a household bulb. If you have BR30 bulbs in your ceiling now, this is a direct swap.
Before installing, check the label inside your can for its maximum wattage and make sure it covers this bulb (65W).
600 lumens, our brightest bulb. Lumens measure how much light a bulb gives off. The frosted glass spreads it into a wide, even flood that fills a kitchen, living room or hallway.
Put it on a dimmer and the light gets warmer as it gets lower, like a sunset.
A frosted BR30 reflector bulb for recessed ceiling lights, built around a real tungsten filament. 600 lumens of continuous, infrared-rich warm light with near-perfect color. It dims beautifully and fits any standard E26 recessed can.

Strainless Recessed vs LED Recessed
What's the difference?
Here is what our spectrum report measured, next to a typical LED recessed bulb.


Strainless figures are from our BR30 spectrum report. LED figures are typical for standard LED recessed bulbs and vary by brand.
