Let's say my lens has a minimum focusing distance of 80cm, and I want to photograph a subject in the shadows at first light in the morning. I want to illuminate the subject only minimally (the video light is on the hot shoe) with very low light. What power would the video light need for…
We are looking for a new ceiling light for our kitchen (about 4.50m long and 2.90 wide / approx. 13 m²). It should be a flat lamp and without any gimmicks like RGB or changing the color temperature. But we don't know exactly what color temperature and how many lumens the lamp should have. The…
I have two to choose from that I think should be sufficient for my small, darkened room. Which is better, or do you know of a good one for around €60 maximum for a small room that can be completely darkened. https://www.ebay.de/itm/375074163856?var=644499327402&_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao% 3D1%26asc%3D20240315173020%26meid%3D59a9852bb6ac43adae7d03a3d2abd682%26pid%3D102069%26rk%3D1%26rkt%3D1%26itm%3D644499327402% 26pmt%3D0%26noa%3D1%26pg%3D4375194%26algv%3DRecentlyViewedItemsV2SignedOutMobile&_trksid=p4375194.c102069.m5481&_trkparms=pa rentrq%3A94fe061e1910a8d8c7d9650dffffa03a%7Cpageci%3A165cdf01-649e-11ef-b404-261b9c615d1b%7Ciid%3A1%7Cvlpname%3Avlp_homepage https://www.ebay.de/itm/166263210383?_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao%3D1%26asc%3D2 0240315173020%26meid%3Dff28e5aef20f48c7be7bdcd11cc10398%26pid%3D102069%26rk%3D1%26rkt%3D1%26itm%3D166263210383%26pmt%3D1 %26noa%3D1%26pg%3D4375194%26algv%3DRecentlyViewedItemsV2SignedOutMobile&_trksid=p4375194.c102069.m5481&_trkparms=parent rq%3A9500bdd21910a57aa3fbb2ffffffd7c4%7Cpageci%3A80890b17-649e-11ef-aa67-ba9a2eff0e18%7Ciid%3A1%7Cvlpname%3Avlp_homepage
I want to get a projector for my bedroom so I can watch movies from bed. What should I look for, such as price or what requirements I need for a good picture? Are there any differences? From where I'll place the projector to the wall, it's about 3 meters. And is there good value…
Lumen = luminous intensity (luminous flux), OK. But it says, for example, 100 lm/m². So, if the packaging says, for example, 100 lm, and the living room is 20 m², so 20 m² x 100 lm/m² = 2000 lm… argh, illogical. 😖🫣 What lm value should be on the packaging for a 20 m² room?…
Hi, can you recommend me a flashlight which is 1. very bright (preferably at least 2000 L) And 2. Which is not quite as expensive (max. around 70€) Thank you in advance LG
Hi, if I have one flashlight with 100 lumens and another with 200 lumens, can I say one is twice as bright as the other? Because, for example, when it comes to decibels, two motorcycles aren't twice as loud as one.
Hello everyone, I'll keep it brief. We always play soccer in the evening, and as usual, it gets dark over time. However, we don't have floodlights to illuminate the field. It's one-third the size of a football pitch. Now the question is, how can this be done most effectively and, above all, inexpensively? I was…
Hello, Why can two LED lights have the same wattage but very different lumen ratings? For example, two 4 watt lamps both have about 4 watts (4 and 4.2 watts), but the first has 250lm and the second 470lm. Are there any advantages or disadvantages besides the brightness? For example, regarding flickering. LG
Hey guys, which of the three would you recommend? So, which one has the best performance? I'm not that knowledgeable. Thanks in advance 👍🏽
