Thank you for this. I'm in the market for similar sized/power portable light. It doesn't look like the tilter attachment has a umbrella hole? My use case would often be to use the included reflector + umbrella. Bummer if that isn't possible with included accessories. Also, I just realized I don't actually know the difference between daylight and planking curve. Not sure if you've already covered that in a video but if not could be a good topic to include some day for less technical people like me? Love watching your videos!
@@jmcmedia9971 that is a great point about not having the umbrella adaptor on the tilter. Ok daylight v plankien..... Essentially most lighting manufacturers follow the plankien curve, because that gave them a continuous standard curve line to follow. It was calculated in 1848 by William Thompson. it was theory because the technology didn't exist to prove it. In the 1960s (could have been the 1970s) Spectrometers were used to get actual sunlight reading to make the standard for the daylight curve. Most cameras follow the daylight curve at daylight Kelvins Williams calculations were actually correct, if you take readings of the sun in space it is on the plankien curve, but the sun is slightly greener on earth as a result of our atmosphere. Recently a TM-30 standard was devised that uses the plankien curve at low CCTs and moves up to the daylight curve at high CCTs. While it is recognised by most camera manufacturers, lighting manufacturers and spectrometer manufacturers are reluctant to adopt it.
The knob is set “left to loosen” but it might still tighten if the load goes downward. Happens to me with grip heads when adjusting boom arms. The knob, like, remains stationary somehow, but relative to the falling load, it’s turning righty tighty. That’s Newtonian Gripology for ya 🙃
@@SrBlue-wb9pu I have no idea about any of this USB-C stuff. It's all moved on since I purchased my power banks. I would just be guessing if I gave any recommendations
1% of the output of this lamp will be dimmed by other LEDs of the same type, which is very good. The actual output of 1% of other brands such as zhiyun x100 is as high as 10w, which affects shooting in low-light environments. It’s a pity that this lamp does not have PD 140w input, does not have a battery handle like Zhiyun x100, and the mount cannot be used with other brands😭 If this light can be used with nanlite modifyer, such as fresnel and spotlight mount, it will be very attractive.
Getting the product for free means a conflict of interest. It affects your review whether you realise it or not. No reviewer can claim to be giving their honest opinion after receiving a product from the manufacturer (or an agent), it's psychologically not possible. These are cheap products, buy them with your own money so you can truly give your most honest opinion, your viewers will thank you for it. Also, you have to live with them for a while, recently a studio burnt down after a Chinese brand of lighting, Colbor, shorted, iirc it was the power supply. The device was found to have not complied with electrical safety regulations. This isn't something most reviewers cover but should. Run the SSA certificate to check -it's literally the most important aspect of any of these devices.
@@robertsaca3512 Let me explain my reviews, and my work situation. I am a working gaffer, This RUclips channel is a hobby in my spare time, I own a lighting business, and have been a gaffer for over 25 years. Over 25 years I have had my fair share of issues with products. So if I think a product is no good I simply don't review it. I have no contracts binding me to do a review, and manufacturers that insist on this are told NO! Not only CAN'T I guarantee them a review, I can't guarantee when it will be done, because testing takes forever. The only contracts I will sign are NDA (Non Disclosure Agreements) so I do have to be careful what I say in this reply. Most products that fail reviews have a price tag of $3K to $8K. So far this year that has come to something like $18,000 to $20,000 of products I have not reviewed. This can be due, but not limited to, I think it is rubbish, it uses someone else's intellectual property, safety concerns, and on occasion no visible certification or missing information. In these cases I will let the manufacturer know why I have failed the product. Then if the product is cheap it goes in my bin, if it is expensive then the manufacturer will take the product back. So I don't get to keep or sell it. As a result of my testing several brands have had to do recalls on products. Or delay the release of products. Just because a product has passed CE or other certifications doesn't mean much. I have had products (all expensive products from major brands) fail because the design was changed AFTER certification. Sometimes a firmware update can cause massive safety issues even after a product has passed certification. For example so many lights have software driven on/off switches (to avoid or reduce in rush currents). This can result in lights partially turning on or off during software crashes. For example I have managed a few time during testing to have lights running at full power with no cooling fans running. As a working gaffer in Australia all my AC powered equipment has to comply, and be tested to AS/NZS 4249. Which is how I catch some of these issues. If a product is coming to me via an Australian distributor it may not have the original factory power supply or IEC power leads. Sometimes remote controls are removed because of the button battery. So I can only test what I am given. I'm not just taking these things out of the boxes and filming a review. As for getting the product for free influencing my review even on a subconscious level, I 100% agree. Which is why I point this out. As for buying a cheap light being appreciated by my viewers. I like to think that my audience can consider how long it takes to test a light, collect the data, film the episode, and edit the episode, divide that time by the episodes revenue (the free light and the pop up advertising) and conclude that this episode is not financially worth me doing, especially as I don't even have affiliate links, because I believe these take money away from distributors. What website do you go to to run the certification number through, I haven't been able to find anything, Energy Safe Victoria (the governing body where I live) has been no help at all. This is something I would love to have in the episodes.
The only light review that matter!

Would love to see a review on the gvm 650b and 1200c pro lights
@@Jaysonware GVM have sent me something, but it is a long way down the list of reviews I need to do first
hola, Which power bank or V battery do you recommend, that is not expensive?
@@SrBlue-wb9pu I have no idea about any of this USB-C stuff. It's all moved on since I purchased my power banks. I would just be guessing if I gave any recommendations
And I thought the x100 from zhiyun was teeny tiny this thing is super small!
