Rated 5 out of 5 by misbe Howard Electronic Ballasts
I purchased six of these to replace the conventional magnetic ballasts that were used in my garage and workshop fixtures. Winter temperatures gave me a no-start or flicker below 55-60 degrees. The Howard ballast was one of the very few rated to operate down to 32 F (without resorting to high-output tubes). The fixtures now start instantly and run flicker-free in 40 degree conditions.
Installation advice from Howard Lighting: sand the paint from the mounting foot of the ballast (where the sheet metal screw secures the ballast) and add a ground jumper to the input cable/fluorescent fixture ground.

Rated 5 out of 5 by Aaron1 high performance
Bought a case of 10 for a friends garage, they replaced magnetic RS ballasts that had intermittent starting below 32°F/0°C , these Howard industries ballasts will start down to 0°F with no issues and the sylvania design 50 (5,000k) lamps warm up in the 4 lamp troffer fixtures within 10 minutes

Rated 1 out of 5 by DeadBulbz Very Poor Product Lifespan
Bought 2 of these less than 2 years ago. Both are now dead. Very disappointing product lifespan.

this is the 2 nd time that I had ordered from them the first time I could order on line the the 2 nd time I had to talk to a person both times I was very happy with the service and response

Rated 3 out of 5 by Nelson Decent Electronic Ballast
This ballast seems to work well. It could be built better, however. The case is thin and flimsy. Also, the yellow wires come out on the same end as the red and blue wires. Usually, it is more convenient to have the yellow wires exit the other end of the ballast since they connect to the opposite end of the tubes.
This ballast does not have "end-of-life" protection, so tubes will flicker and flash, and sometimes even crack when they fail.
For a little more money, the Advance ballast is a little better.

Rated 5 out of 5 by Teenangel This ballast solved a very exotic problem for me.
The lamps in which I was replacing the ballasts are on circuits controlled by a carrier current switching system--a system which transmits signals over the building wiring to electronic units which activate and deactivate the control relays for the various circuits. Magnetic ballasts act as an attenuator for these control signals and I was unable to overcome that effect, thus losing the "Off" function. I could turn the circuit on, but the magnetic ballasts would not allow me to turn the circuit off, even though I installed special electronic "traps" which were supposed to isolate the magnetic ballasts and allow the signal to not be attenuated. These electronic ballasts do not exhibit the attenuation or saturation of a magnetic ballast and thus allow me to control both of the functions.
The ballasts are very competitive in pricing when compared to most magnetic replacement ballasts. They do not generate as much extraneous electrical noise. And they seem to generate less heat during operation.
Their reliability is guaranteed and has proven superior to some other electronic ballasts I have used.
All in all, I am very pleased with quality and performance of this ballast.
