GOODSMANN transformers come with a digital reading, automatic timer, and clock controls facilitating easy light automation. To decide which transformer best suits your needs use the below formula:

Total watts of light bulb * number of light bulbs = Minimum transformer size.

A standard bulb requires 30 watts of power. If you have 10 30-watt bulbs needing power, you will need at least a 300-watt transformer.

30-watt light bulb * 10 light bulbs = 300 minimum transformer size.

We recommend purchasing at least 100 watts more than your calculated minimum transformer size. Once you discover how easy it is to install/complete lighting projects, you may wish to add additional lights using the same transformer.
