I am trying to emphasize certain shrubs and their texture in my garden while also creating shadows. I’m not entirely certain what wattage is too much and what wattage would be sufficient for an led light. Also, I understand that leds come in different color temperatures. I’m thinking of using warm white. what’s your recommendation. I’m hoping you can help with this. Thanks,

Henry C.,

Hi Henry,

Thanks for taking the time to submit your question.

The two points I will go over are LED to Halogen wattage equivalency and also LED lighting color temperature options and best application.

1. With LED lighting, you can conservatively multiply total wattage consumed by 7-10 (depending on the quality of the LEDs) to match its halogen equivalent. Example: a 5-watt LED-conservatively multiplied- is equivalent to a 35-watt halogen.

Note: For your application (accent lighting), either a 3-watt or a 5-watt LED would be sufficient.

2. LED lighting color temperatures are generally measured by their corresponding degrees in Kelvin. For example, a piece of steel heated to 2,700 degrees Kelvin will burn a warm yellow-ish hue and as the heat increases the color ranges from white (at around 3500K) to blue-ish (at around 5200K+), resembling day light.

Note: For a traditional designed home and garden, I recommend 2700K (Warm White) and for more modern designs, I recommend 4100K or higher.
