This is the new NorthLux™ 95 CRI 6500K BR30 LED Bulb for Artwork & Painting (for the sake of brevity on this website, it will be called the, "BR30 LED Bulb", "LED Bulb" or simply, "BR30").
It is designed to be a direct replacement for a 60 watt halogen incandescent bulb, but instead of an incandescent yellow, the BR30 produces a slightly bluish-white light that's very reminicent of natural light streaming from a north-facing window.
This "bulb" uses a miserly 12 watts, but generates as much light as a 60 watt halogen incandescent bulb!
SIZE
The BR30 is easy to use -- actually, to borrow a phrase from an automobile insurance commercial, "so easy a caveman can do it."
All you need to do is unscrew the existing bulb and place it somewhere where some asshaberdasher won't stomp on it and break it, and screw the BR30 in in its place.
The BR30 -- unlike most other LED retrofit bulbs -- can be screwed into a fixture controlled by a standard DIAC dimmer; the type of dimmer most often found in homes, offices, art studios, etc.
This product is line-powered, so I do not have to tell you which part to remove, huck into an open-pit gadolinium mine, and then rather emphatically tell you not to. 
This is a retrofit LED light bulb, not a flashlight meant to be thrashed, trashed, and abused. So I won't try to drown it in the toliet tank, bash
it against a steel rod or against the concrete floor of a carport in effort to try and expose the bare
Metalmarineangemon - er - the bare Metaltrailmon - um that's not it either...the bare Metalsusanoomon...er...uh...wait
a sec here...THE BARE METAL (guess I've been watching too much Digimon again!
- now I'm just making {vulgar term for feces}
up!!!), let my mother's big dog's ghost, her kitties, my kitty or my sister's kitty cat piddle (uranate) on it, hose it down
with my mother's gun, run over it with a 450lb Quickie Pulse 6 motorised wheelchair, stomp on it, use a medium ball
peen hammer in order to bash it open to check it for candiosity, fire it from the
cannoñata, drop it down the top of Mt. Erupto (now I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a laser-type device on a
platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that
Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located
at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is
an active volcano on Piñata Island), send it to the Daystrom Institute for additional analyses, or perform other indecencies on it that a flashlight
might have to have performed on it. Therefore, this section of the BR30's web page will seem a bit more bare than this
section of the web page on a page about a flashlight.
The published information about this bulb is as follows:
Color temeperature of 6500K
High CRI: 95
Compatible with 120 VAC (Volts Alternating Current), 50-60 Hz
Conveniently screws into any standard E26 Edison socket
12 Watt power consumption
800 lumens - equivalent to a 60W halogen bulb
Dimmable (Webmaster's note: This is outstanding to see in a line-powered LED "bulb"!!!)
25,000 hours lifetime, 3 year warranty
The BR30 has a "comfortably cool" color temperature that rather nicely simulates what you might expect to see from natural light streaming in from a north-facing window on a sunny afternoon -- no longer do artists need to put away their canvas & pigments when the sunset is looming near; just screw in one or more of these babies, direct (aim) them toward your canvas, and paint like it's afternoon!
One of the best things about this LED bulb is that it's dimmable on a standard DIAC dimmer -- this is the type of dimmer (usually seen with either a knob that you spin or a slider that moves vertically) most frequently found in homes, offices, art studios, and the like. 
Even when set to minimum intensity, no perceptible flickering was evident.
Please do note that I don't own or have access to a colorimeter or even an artist-grade color chart, so I'm simply not equipped to either measure actual color temperature or furnish "north-facing" and "illuminated with the BR30" comparison photographs.

I just rent a room here; the house in general is a total disaster area and I would never keep my own place this dirty. 
I would have loved to photograph a bowl of fruit to show off the colors, but I haven't seen such a critter since moving here in mid-2015.

Deliberately underexposed to show detail -- as you can spy with your little eye, the power distribution is somewhat Gaussian in nature, and is EXCEPTIONALLY SMOOTH.

A beam cross-sectional analysis would normally appear here, but the ProMetric System
that I use for that test was destroyed by lightning in mid-July 2013.
TEST NOTES:
Evaluation sample of this lamp was sent by J. of Waveform Lighting on 05-16-18 and was received at 10:28am PDT on 05-18-18 (talk about, "speedy delivery!!!") 
The, "
" (UNDER CONSTRUCTION) icon was appended to its listings on this website because it is in an incomplete state (two or more crucial photographs are missing); once those have been added, this icon will be happily removed.
UPDATE: 00-00-00
PROS:
DIMMABLE!
Color temperature (although subjectively a bit cool) looks right on par with advertised value.
No IR or UV emissions that can damage delicate artwork or museum installations.
Appears to be at least as bright as advertised.
Runs cool.
NEUTRAL:
A bit on the large side, but this may just be personal opinion.
CONS:
None that I've yet to discover.
