Our community has rated this post as helpful. If you agree, why not thank dong888

For comparison:

1. Sofirn Q8 Plus: *16000* lumen and 2. Costco Infinity X1 (5000 lumen, earlier model, this current model is 7000 lumen).

I have both. Q8 plus is super bright and has nice form factor. It is best for short time usage only as it only last for maybe 3-5 minutes at high settings and 1-2 min at turbo. Costco's Infinity, X1 5000 lumen, lasts more than double the usage time. And it is already very bright for everyday usage. While there is noticeable difference between the two, the extra brightness is no longer useful. If I could only get one, I will pick X1 w/ 7000 lumen due to battery duration. It also has an battery case to take in AA batteries in case build in lithium battery runs low. Highly recommend X1. But if you are flashlight hobbyist, get both.

X1 has adjustable lens but not as focused as I would like it to be. Specs says 250m.

Have one from last week.

Its not the greatest if you read the Flashlight subreddit, but then again for MOST people. This thing works great, and the rechargeable battery is decent, the beam is decent, the throw is decent, the focusing system is decent.

It's heavy, I bought it because its long enough to replace a baton type maglight that is in my car within arms reach.

It shows in the product details that it has a narrow to wide adjustable focus.

I agree, I returned it for that reason
