I own a lighting company and after ordering a smaller number of these to test out I went back and ordered another 500 of these. These replaced my incandescent 7-watt G50 bulbs. They are easily as bright, the dimming is just as smooth (with NO flicker when dimmed fully down as I've found can sometimes happen with dimmable LEDs), and best of all they are shatterproof. They even weight less than my old bulbs which will make my work from the top of a ladder easier and safer.
Before these, I would install the old glass bulbs at each event to avoid breakage (which meant they had to be removed and reboxed during strike). Now, they are transported already installed in the string, greatly reducing the labor of installation and removal.
Perhaps best of all, they consume a mere 1/7 of the electricity of my old fleet of incandescent bulbs, so my time spent wiring (and dividing up loads based on the power that is available at each event) is also greatly reduced. Before these, I could plug no more than 3 50-foot strings end-to-end (which meant more extension cords, more dimmer boxes, but most importantly more time and energy wasted). Now I can plug over 20 50-foot strings end-to-end, off of a single extension cord with a single dimmer box, all plugged into a single circuit!
These are a no-brainer! I'll make my money back on these in a single job.
