Frequently Asked Questions

Quick answers about Par38 Bulbs before you buy.

PAR38 bulbs have a larger diameter and are typically designed for outdoor use. Their sealed construction and higher wattage capabilities make them more durable for weather exposure and larger spaces.

Yes, but you must ensure the bulb is specifically rated as 'damp rated' or 'wet rated.' Wet-rated bulbs are designed to withstand direct contact with water, such as from rain or sprinklers.

If you choose LED versions, they are highly efficient. An LED PAR38 can provide the same brightness as a traditional halogen bulb while using up to 80% less energy.

Flood bulbs have a wide beam angle (usually 40 degrees or more) to illuminate large areas, whereas spot bulbs have a narrow beam angle for focused, dramatic lighting on specific objects.

Most standard landscape fixtures are designed for PAR38 bulbs, but you should always check your fixture's manual to confirm the maximum wattage and socket type (usually E26) before purchasing.

High-quality LED PAR38 bulbs generally last between 15,000 and 25,000 hours, significantly outperforming halogen alternatives which often burn out after a few thousand hours.

For a natural look in gardens and walkways, look for 'Warm White' (2700K to 3000K). For a more modern, crisp look, 'Daylight' (5000K) is a better option.

Not all are. If you want to adjust the light intensity, you must specifically look for bulbs labeled as 'dimmable' and ensure your dimmer switch is compatible with LED technology.
