You should not stop cycling to work or make use of nature just because we are moving towards darker times. The environment around around you still have quantities to offer in the dusk, but it is important that you are prepared in the dark so you are safe and secure, whether out staying in town or out in the woods and fields.
Many people choose to invest in a headlamp, a real toppenidé!
-However, it is a jungle out there with all the different concepts in terms of how much headlamps illuminate. Here is a little guide to explain to you what LED technology and lumens actually is.
In earlier years were measured everything out light in watts. Then they had either dipped beam or main beam, easy on geschwint. Like everything else, go ahead technology and today there are more and more people use out of LED technology (Light Emitting Diode) With this technique to get the lights glowing stronger and have much better light diffusion. How does it happen? Yes, we will explain. What then is LED? And, what is the meanings of GU10? According to Ledbulbbay, an LED is a semiconductor that radiates in a narrow light spectrum as soon as you have connected power to it. You have advantages of LED technology so as to have a lifetime of up to 50,000 hours, very low power and develops very little heat. This is also the only source of light that can change color, cool huh? This sounds quite ingenious if you think about all the advantages: you get lots out of light, you can adjust the brightness as required. You have a battery that lasts forever (almost), while it is shock resistant. We must mention the negative with LED technology as well. The diode is relativit heat sensitive and therefore must be cooled by means of cooling fins. This means that the lamp housing is slightly larger / heavier. Meanwhile, if you weigh plus to minus with LED technology becomes scales on the plus side still very heavy and convincing! Since the lamp is a bit heavier so is it also demands that the headgear is in good quality so that it can cope up the lantern . So our advice to you is to invest in a good band, so that the lantern is good and stable at the head, whatever you choose to use it!
Here you see one of our Better Head Bands And Other Products Suited to our Shin Magic Lanterns:
What are lumens? Definition: Lumen is the unit of luminous flux. Lumen is the luminous flux of an isotropic light source, which irradiates a solid angle of 1 steradian. Lumen thus obtained by multiplying candelas with solid angle. Lumen value is constant regardless of the angle of the light beam. -Jättekrånligt right? If we’re going to try to explain it in plain Swedish so the lumen is a measure that most lyktproducenter use to compare their various lanterns. It is a measure of light output and describes how much light source emits a total in all directions. At the same time it helps “lumen expression” the customer as much anyway.For you to get a relative to the amount of 400 lumens and 500 lumens ect. in fact we have made a table where we put Lumen and more Varda league watts to each other.
|Tungsten, Watt||LED-lampa, Lumen|
|15||120 – 135 lm|
|25||220 – 250 lm|
|40||410 – 470 lm|
|60||700 – 805 lm|
|75||920 -1055 lm|
|100 W||1330 – 1520 lm|
|150||2140 – 2450 lm|
|200||3010 – 3450 lm|
-Note: In the table are approximate values. The range is due to different types of lamps give slightly different values. The differences can not be seen by the naked eye.
However, remember that the light output of the bulbs can vary quite strongly. A higher drive voltage increases the yield at the expense of life while halogentillsatser can extend the life and thus allow better exchange. Lamps with low power can produce lower yields due to higher relative heat loss. Good luck with lyktköpet! Here are some lanterns from our paybacks on our website, a lot of light for your money!
