We often had helicopters flying above us but this was as silent as the night and about seventeen storeys above street level." The object flew off but returned later, by which time she and Lennon had set up a telescope through which they could view it in more detail. "The light paranormal light orbs was so brilliant coming from the craft that no additional details could be seen. We did take a couple of pictures but they turned out overexposed." They also rang a local newspaper to report the sighting and were told at least seven other people had seen the UFO too.

While walking home. From ridge rd, and Colfax, to get smokes. When i almost got to end of rallison almost to elm st. (49th) i seen a white dog out side. He was big so i watched him a i walked passed. No steet lights so it was dark. And my feet were killing me. night air was hott. By time i was heading back i was tired. But as i passed this dog i seen a odd bright star i thought. Didnt pay it much because i was just wanting to get home. And was sore. But i looked at it again. And gave it a look.

After regaining his composure, the witness moved his truck forward about 15-20 feet. It was then that the man saw the object now behind him in his rear view mirror. The object looked similar to the object that he had initially seen, but couldn’t be sure that it was indeed the same triangular object. The man parked his truck and exited the vehicle to obtain a better look at the mysterious device. The object was directly behind him and about three hundred fifty feet in the sky. Within about 30 seconds, the object departed toward the north and was lost from sight.

LEDs only look like their finished product when the ‘die’ or ‘chip’ is set or encapsulated in a resin or plastic which is known as potting. This plastic shell helps out in many ways. It holds the very delicate system together, mounting the LED is made far easier in products and it acts as a lens or refractive intermediary to boost the light from the semiconductor. As you can imagine there are a lot of different methods of potting these chips to make LEDs – some cheap and some expensive which result in different light output.

The G-U90W is recommended for about 50,000 hours and covers a 13.5m2 growing space. UFO LED ones are one of the most popular products. They are named according to their shape. They are round, like small UFO spacecrafts. They are energy-saving. The consumption of energy of a LED light is 80% less than that of an incandescent light which has the same luminous efficacy. To draw another comparison, while a HPS (high pressure sodium) grow light is working with 400 watts of energy, a UFO LED light use only 80 watts, four fifths less than that of the former. However, the output is the same.

Thermal management of LEDs is a science in its self, there are a multitude of methods with the best not using fans (convection) at all. When you include a fan in an LED grow light to manage heat issues it introduces a moving part Moving parts have a habit of breaking down long before your LEDs fade. However, if you must purchase a unit with fans in it, make sure the LED has a long warranty and the fans are rated for a lifetime that exceeds that of the LEDs.
