We needed a sensor security light for our front yard at our new place. My first thought was the typical standard dual PAR38 sensor flood light setup. These use 2x 150 Watt PAR38 halogen globes. However at Bunnings we saw a new version with 2x 10 Watt PAR38 LED globes. This is a significant power saving over the traditional type.
The version we purchased required electrician installation, but was an easy install for our electrician because the cabling was already in place. The unit is IP44 rated, so is weather proof for outdoor installation. It does need to be out of direct rain though. Ours is installed under the eaves. They can be wall mounted too.
I was concerned that it might not be as bright as the traditional 150W globes. It is somewhat slightly dimmer than the traditional flood lights, but is still more than adequate for our needs. The dual unit sufficiently lights up our entire front yard, which is about 6m across.
The default twilight setting was fine for making sure the unit didn’t activate during daylight. The default duration time was 2 minutes 45 seconds, which I’ve left alone. I also didn’t have to touch the sensitivity setting. It does activate sometimes when ceiling fans are turned on or off in the house. There are also some other inadvertent activations for no real reason. I’ve been quite happy with it’s operation though. I’ve been able to set it to activate only when someone enters the front yard, or leaves the front door.
It’s also useful that the unit is rated for 150W globes, so if you do decide that the 10W LED ones aren’t enough, you can swap them out. I bought ours on special for $29.95 at Bunnings.
