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 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.
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.
