Light Sketch Series 5

Vanstory Lighting Company Field Trip

After visiting the Vanstory Lighting Company I came away having learned a tremendous amount about the differences between the use of LED lights and Fluorescent. I found it interesting that based on the markets now (at a commercial level) it almost as cost efficient to use LED lighting as compared to Fluorescent. I was also surprised at the amount of options of light fixtures that are available with a LED lamp. I went into the field trip expecting LED lights to be dimmer and more incandescent than Fluorescent. I was pleasantly surprised that they produce a similar amount of light, and yet their lifespan is much greater, and they are a greener product.
