will a projector work in daylight?

So… projection outside in full daylight — probably not possible anytime soon. ... However, a projection surface is designed to reflect full spectrum light — which reflects the projector and all this ambient light.

Lumens are a very important factor in buying a projector. The brighter the projector the less ambient light matters and the farther you can place the projector away from the screen. If the projector is not very bright, you will only be able to see the image in a dark room.

Regular bulbs work just fine, though, especially if your plants are already getting some natural daylight. They key is to make sure they have the correct color temperature, measured in Kelvins.

['the light must be travelling from a more dense medium into a less dense medium (ie glass to air)', 'the angle of incidence must be greater than the critical angle.']

It's not legal in California, that's for sure. One thing I've seen in Korea is a demon eye that is a result of some sort of "alarm on" light that is reflected through the projector while parked and the car is off.

The price isn't bad either. However, the low resolution means image quality isn't quite as good as some of its competitors, and its max brightness is a bit too low, which means that images can look washed-out when used in bright environments. Still, it's a great portable projector, especially for work presentations.

Yes, you might have some built-in drone lights but typically they are almost invisible during the day and not that bright during the night. This is where drone anti-collision lights come in help you and others see the drone during the day and night. Remember that lights don't solve all your night operational problems.

You can fit an aftermarket HID kit to a UK vehicle, and as long as the beam pattern is correct, the light is predominantly white or yellow-white, there is no glare for other road users, and the light passes all the standard MOT test checks such as being secure and pointing in the right direction, then you should be ...

Although projector headlights are significantly brighter than reflector headlights, they are usually road legal. ... In fact, if you're looking to use upgraded, brighter headlight bulbs (for example, if you use xenon HID bulbs or want to install an HID conversion kit), projector headlights are almost always necessary.

As the light fades during the evening, the flow stops and the fixture is powered on. This allows for “Dusk-to-Dawn” light output. Being that photocells sense ambient light levels, they will automatically adhere to seasonal changes and are not affected by daylight-savings time.

Turn off the lights. Stink bugs are attracted to lights, so it's recommended to keep outdoor lighting to a minimum. During the evenings, turn off porch lights and pull down window blinds to prevent light from spilling outside.

HIDs are better for projector headlights Although LEDs will fit and work, from experience, they will not perform as expected. In most cases, your stock halogen bulbs will be brighter than LEDs in projector-type headlights.

Just as long as the bulb is mounted in a moderately sheltered light fixture that protects it from rain, snow, hail, and other elements, then it's fine to use a Philips Hue bulb outdoors. Just know that the bulb may not last as long as it could if it were used indoors in better conditions.

Re: MD Legal HID Limit? (chaos2984) Pretty sure they can be lowered as long as they pass the 21" rule. Coming from someone who had an HID retrofit (read: not drop in, s2k projector retrofit into stock housings), it IS ILLEGAL but if it's done right, you won't get hassled.

Daytime lights to be mandatory. New European laws will force all cars sold in the UK to be fitted with automatic daytime running lights by 2011. The EU believes that daytime driving lights increase a car's visibility and help reduce accidents by three to five per cent.

They are lightweight, aesthetically appealing, energy efficient and long-term cost effective. Some of the disadvantages are that they are not suitable for dimly lit applications, can require frequent adjustments throughout the day, have limited viewing angles, and their purchase cost is relatively expensive.

DLP projectors deliver sharp images, don't need any filters, have a better response time as well as 3D capabilities. The effective lamp life of a DLP projector is only 2000-5000 hours and some people see colour ghosting/banding in some scenes.
