Questions & Answers

  1. What is the average lifespan for an LED standard incandescent replacement?
    About 35,000 hours.
  2. What type of high efficiency light do you recommend for a grow light?
    There are many options that we would recommend. It depends on what you're growing, where you're growing it and how long you are going to grow under the light. We are here to help you, if you'd like to discuss your growing needs. Give us a call and we can discuss options for you specific application.
  3. Is it cost effective to buy the higher priced, efficient lights?
    It is worth the investment. It is a much higher upfront cost. However, you won't need to replace that light as frequently and there is much less maintenance. You only need to buy the light once and if maintained properly, it will last you for years.
  4. How long does it take to charge the solar lights?
    Depending on which solar light you select, it varies on how long you need to charge it for. Each of our solar light options comes with a user friendly guide that tells you how long it will take to charge.
  5. What is the difference between lumens and footcandles.
    A lumen is a measure of light at the originating point. Lumens are the initial amount of light output by the bulb. A footcandle is the measurement of light on a surface. So, lumens are the measurement of light coming out of the bulb and a footcandle is the measurement of light on the table top or plant surface. Footcandles vary by location and the object being illuminated. You can have different footcandle ratings in the exact same 10' by 10' area, depending on how far away from the light source you are measuring. A footcandle measurement taken 2' from your light is going to be significantly higher than measurement taken 10' from the light.
  6. Do I need to use both a metal halide and high pressure sodium light for flowering and budding plants?
    Metal halide and high pressure sodium bulbs can both be used for flowering and budding plants. Metal halide lights are a more prominent, primary light and they promote vigorous growth in plants. High pressure sodium lights promote flower and budding. If you are looking to produce more fruit then it is time to swap over to a HPS. If you are growing, lettuce, kale and spinach then stick with the metal halide.
