FREEME ✌ LUMINTOP CL2 4*SST20 NW 630lm Type-C Camping Lantern Group Buy - ALIVE!!!

Interested

Yes, but you still need to tell Lightroom what the true white balance value is. You can choose “Auto” in Lightroom, but that’s no guarantee that it’ll be correct. I’ve been using Lightroom for almost a decade, and I know it’s a crap shoot.

Best way is to place a grey white balance card in your photo and use that to set white balance in Lightroom.

So close to completion but got interrupted by all the recent group buys.

You misunderstood the topic. It’s abut finding out the color temperature of the lantern, not about editing the picture and setting the white balance in the image file.
And finding out the white balance ist accurate with Lightroom.
A greycard isn’t neccesary if you take a defocused picture or blur it afterwards.

Replied.

Thank you. Ordered!

don’t know if too late but interested. Thanks

Interested

Still interested, even though it has no magnet. Maybe I can fix that.

Okay.

I won’t say that I’m 100% satisfied.

The light itself is great. I’ve always wanted an AA based quality lantern. My problem is the 5000-6000k. Mine is definitely not warm, especially compared to the LT1. There no ‘’warm white magical camping mood’’. It works but… meh…

I'm quite sure it is in 3650-4000K for medium brightness. You mean they used new emitter now? When did you order yours?

I was among the first 30. I’ll try to take a picture compared to my LT1. It’s definitely not in the 3000K range. I would even be surprised if it in the 4500k range but I have no way to test that.

Beside the LED tint, this little lantern is great. High quality build and a lighted switch running from AA is a huge plus for me.

The CL2 has never been advertised as warm white, so why do you expect it anyway?

I wrote the exact color temperature (3650K) in post #126:

Like i wrote last month :wink:

Thanks for the hint to the Olight Bulb, which delivers 55lm of warm wite light (:

Not neccesary, BLF LT1 has 2750K. Lumintop CL2 has 3650K.

CL2 means Clone of LT1 Too (as well)

I haven’t heard anything yet, other than the OP description.

After seeing this, I did a quick search for more UI info. I found that Zeroair reviewed the CL2 and has lots of info about the UI and other details.

While looking through the data there, I noticed that the efficiency seemed to be really low. So I did some quick calculations, and it worked out to:

  • 55 lm/W on li-ion
  • 10 lm/W on NiMH

Those are both pretty low for LED lights. Especially on NiMH, it’s not much better than an old incandescent bulb.

Then I was curious, so I checked the LT1 since the CL2 was clearly, uh, “inspired” by the LT1:

  • 88 lm/W (LT1)

Not great, but not bad either. Mostly just average.

The CL2 kit comes with four 920 mAh cells, or 3680 mAh total. A single common 18650 35E cell holds 3500 mAh. After factoring in the difference in efficiency, this leads to some interesting runtime comparisons, assuming the same lumen output:

LT1 w/ 1 cell: (or a smaller 1x18650 amc7135-based light, like a Convoy S2 w/ diffuser cap)

  • LT1 runs 1.5X as long as CL2 w/ 4x14500
  • LT1 runs 8.4X as long as CL2 w/ 4xNiMH

LT1 w/ 4 cells:

  • LT1 runs 6X as long as CL2 w/ 4x14500
  • LT1 runs 33X as long as CL2 w/ 4xNiMH

Normally, a boost driver should be more efficient… but it looks like that’s not the case here. The CL2 in boost mode is an order of magnitude less efficient than a simple linear driver.
