Eclipse LED digital ballasts are more efficient, quieter, cooler, and
softer on the bulb. Digital ballasts do not have any of the usual
transformers, capacitors or igniters; instead these ballasts have
electronic circuitry to do the same job, more efficiently. What might
take a standard coil/magnetic ballast 680-700 watts to fire a standard
600 watt bulb, may only take a digital ballast only 600-620 watts to
fire the same bulb to the same brightness.

That's OK... the shill isn't talking about fluorescent ballasts, they're
talking about HID ballasts (mercury vapor, high pressure sodium, metal
halide). Digital technology could be used for these by using "steppers"
to ramp the voltage up and down based upon current detection.

While you are technically correct, about a LED being mentioned in the
original post, the difference between sodium/mercury-vapor and
fluorescent BALLAST is minimal, to an engineer.

Voltage step-up/step-down, or even wave shape has nothing to do with
"digital."

While not absolutely necessary, a digital wave shape will be of a square
wave, however ramp and even sine can be handled with processing. *And, a
simple flip-flop circuit can generate a square wave, process this though
a current regulator, then a voltage regulator and you, basically, have
your "digital ballast", but it has nothing to do with anything truly
"digital."

The name "digital" is more of a marketing scam than anything else it
its' use in describing the ballast, kinda like "solid state" (a pencil
is solid state!), "state of the art" ("new" is simply relative),
"space-age" (products developed after successful space flight), etc..

Is the outer shell glass, or something more durable, like a polymer?
With glass, if the inside gets broken, there's a pretty good chance
the outside cover would also be broken by the same trauma.

It is Glass -but- not 'thin' Light Bulb Glass
It is Thicker and More Durable like the Glass
on a Halogen Bulb

The 'process' seems to be that the Start-Phase

of the larger CFL Spiral Tube [Empty Hollow] :
After the Instant-On Warm-Up the Second-Phase
CFL takes over for long-term Low Power Light

Most CFLs 'Fail' due to their Electronics :
Not the CFL Tube itself : This may be a way
to reduce these Failures and Improve the

Our landlord had CFL bulbs installed a year ago in all apartments. They
lasted about 6 months before they dimmed too much or just stopped working.
CFL is a waste of consumer money.

& 75W & 100W CFL Bulbs for a 'Buck' )

The local Dollar-Tree Store has 3-Way 30-70-100
Watt old Incandescent Light Bulbs for $1 a 'Buck'.

The Kitchen's Mushroom* CFLs are 'On' 12-Hours
per Day and Last about a Year. There are 18
CFL's in 2-Arrays of 9-Each {2-Switched Circuits}
The Arrays are at 10-Feet and require a 9-Foot
Step-Ladder to get at them. It's 'nice' to have
to do that once-a-year.
