The recommended lumens for outdoor LED landscape lights depend on several factors including the size of the area you want to illuminate, the purpose of the lighting, and the desired ambiance.

Here are some general guidelines for various outdoor lighting needs:

1. Pathway Lighting: For illuminating pathways, you generally want softer lighting to guide people safely. Aim for around 100 to 200 lumens per fixture.

2. **Accent Lighting**: Accent lighting is used to highlight specific landscape features such as trees, sculptures, or architectural elements. For accent lighting, aim for around 200 to 400 lumens per fixture.

3. Flood Lighting: Floodlights are used to provide broad, even illumination across large areas such as driveways or gardens. For flood lighting, you may need anywhere from 700 to 1,500 lumens per fixture, depending on the size of the area you’re lighting.

4. Security Lighting: Security lighting is meant to deter intruders and provide safety. These lights are generally brighter and cover larger areas. For security lighting, aim for at least 1,000 lumens per fixture, but you may need more depending on the specific security needs of your property.

5. Deck and Patio Lighting: Lighting for decks and patios can vary depending on the size and purpose of the space. For ambient lighting, aim for around 100 to 300 lumens per fixture. For task lighting, such as over a grill or outdoor kitchen area, you may need brighter lights, around 300 to 500 lumens per fixture.

Remember, these are general guidelines and the actual amount of light you need may vary based on factors such as personal preference, the layout of your landscape, and the specific led landscape lights you choose. It’s often a good idea to start with a lower lumen output and adjust as needed based on the desired effect and functionality. Additionally, consider using led landscape lights, which are energy-efficient and long-lasting compared to traditional incandescent or halogen bulbs.
