Easy answers; no and no. While it's true that 'light is light' and that the secret is in controlling the light, not the brand name of the manufacturer, there are reasons pros use actual electronic flash. HD lights are great, but they are not made for photography, they are made to be used when working on a car. As for why pros don't use them. there are many reasons, but most basic is that they are not bright enough, they are HOT and they don't flash. No pro, whose mortgage money and the beans his kids eat comes from his photography, will use lights which restrict his ability to shoot a variety of photographic styles or which limit him in any way. HD lights are absolutely limiting.
They are a step backwards. The logic that home depot lights are fine for photography, would say that continuing backward progress says we'll be using flash powder next. After all, why not save money since we can mix up flash powder in the garage for next to nothing and our only expense would be a small tray for holding it while it flashes.
Home Depot lights work as will any light source, but they are limiting. What happens when one falls over and sets the curtains on fire or and burns a model's face? Hope you have really good insurance! HD lights will work for some things, but they do not allow the latitude needed for general photography. Try lighting a five member band or a car with HD lights. Try lighting any group or using them to overpower sunlight. Try using them in a softbox or with a snoot or grid to control light.
When pros talk about HD lights, far from bragging, they are generally trying to pass on some techniques which will allow amateur or novice shooters to get some articifial light without investing in studio set ups. If teaching is bragging, then maybe they are. Go into their studios and what you'll are expensive and extensive flash heads, not relatively dim jury rigged set ups.
Only on internet forums will you see HD lights as a desirable thing!
