A:Costs of LED lighting products vary widely. Some LED bulbs can cost as little as $1 – $2, but other LED lighting products may carry a significant cost premium compared to standard lighting technologies. In general, LED lighting products are still more expensive than their conventional counterparts, but when the costs of energy and maintenance are included in the total cost of ownership, LED-based products can have a distinct advantage. And differences among LED lighting products typically correspond with differences in various lighting performance features, such as color quality, lifetime, optical performance, and dimmability.
