Popular and proven lighting retrofit kits for 400 watt metal halide, high pressure sodium, low pressure sodium, or mercury vapor fixtures. Whether you have an indoor or outdoor fixture, these typically fit inside and provide great energy savings with decreasing or eliminating maintenance costs, all while increasing light levels. LED, induction, and perhaps fluorescent technology are all included below. There are also some different Kelvin temperature options, but most applications now use 5000K-5500K, which are brighter and emit a pure daylight white color, like the color of the white on this page.

You will see both 150W and 200W efficient options below. If your aim is higher energy savings and keeping the existing light levels or you don't mind a little bit less, we recommend around 150 watts. If you would like to still get over 50% energy savings and make sure your area is still the same brightness or even about 10-20% brighter (depending on your lamp/fixture condition), go with the 200 watt kits. Please check the dimensions of each product to ensure fitment into your fixture. If they don't fit and you have a moderately old fixture, we have plenty of new fixture options as well if a retrofit won't work.

If none of these fit your needs, please contact us or email our sales team and we'll be happy to help you find the right kit.
