Yes, as far as we seem to know now, the pre-production samples have been approved for the most part by the LT1M team.
-(Other team members can confirm if they wish here) So far i myself have given it a green-light to go into production for sale as the same unit as the test samples we evaluated, and hopefully we get a group-buy discount code soon for the LT1M.
Just so I’m clear, the LT1 Mini is already for sale on Sofirn’s site, so our interest list here is for a discounted group buy? This model will look especially good in the same LT1 colors.
Hmm, the Sofirn store website only has black currently. I was al set to buy (with a coupon, even) until I realized that. Any hints at some kind of spearate site or links for the other colours?
Got my LT1 mini in today. It looks boring but I like it, it is useful.
One useful thing that they missed doing: the thing tailstands ok, although the base is relatively narrow for uneven surfaces, but in potential it should headstand extremely well but instead it wobbles because of two bits sticking out from the rim. Those bits are not needed so can be sanded off for a much improved headstand). And if you are into modding anyway, after sanding, buy a chunky 3mm thick 30mm diameter neodymium magnet (i.e. here ) and glue it on top.
Measurements:
*Standby current with switch light engaged: 380 micro-amps (more than a year on a 4000mAh 21700 battery)
*Current at lowest setting: 12.8mA. (13 days continuously)
Edit: this was in simple UI, in advanced UI it is lower: 4mA/40 days.
Current at highest setting: 1.4A (almost 3 hours)
*Tint at warmest: bit under 2700K, duv +0.0030, CRI 94.5, tint does not change much with output.
*Tint at coolest: about 4700K, duv +0.0050, CRI 92, again tint does not change much with output.
*Tint in the middle: 3700K, duv +0.0013, CRI 94
*Lowest output about 1.3 lumen, highest about 180 lumen, no great difference between the tints. Edit: the lowest in advanced UI is lower: 0.4 lumen.
(with the notice that these numbers are approximate because my sphere does not easily measure lanterns: you have to lower it inside the sphere to prevent too much light directly escaping through the entrance hole, but then some light goes past the baffles directly on the luxmeter sensor giving a bit too high reading).
Somewhere it was suggested that the top have a threaded hole that you could use for stowing a wide, detachable base on. I thought that was a great idea. Especially if the bottom had an identical attclaching method, whether 1/4-20 bolt hole,cylindrical slip fit, or magnet.
