UF-T20 REVIEW
Hi,
Ordered one from Wallbuys, shiping was fast i think from their part but my local postal service seems to slow thing a bit. However the flash now is here with me
Build quality at first look seems good. I have an M2 which is the upper standard in terms of build quality and finish, and T20 is almost there in finish and in build, M2 still I find it superior overall.
The body looks sturdy, and in looks is discrete IMO.
The lens looks impressive it works good, well maybe not that good as I was hoping still acceptable, more on that later.
Probably as you all know already stock its an XML T6 (I believe) and in max should be at 2 A. Unfortunately I cant make reliable measures right now bc my multi meter is not so reliable. Since I like the numbers i made some measurements in throw and at max @1 meter measure ~22K lux . Its not something to wow but not bad either. Tint look neutral to me still have to say that I don’t have seen to many different tint of XML leds. If you want to use for ordinary work than its more than satisfactory in stock condition, for me that bought it just for playing with throw, its not enough.
So let’s go in the sec part of review which is one of the first moods of me actually.
I want to change led and driver so I have paid for some xpe2, xpg2, on cooper and some xre together with some drivers 1.4A 1.7A 2.4A and some nice batteries but of course with my bad lack I have nothing show up till now. So I have to say that this mod is a review in progress.
Still as u know I try too progress with what I have in my disposal, so I took an cheap xpe zoom light with an unknown bin, take it apart got the led and try it with the xml driver. I think its around 1.4A driven now at max but this is a guess not an actual measurement.
Well the total output in lumens go down of course(very visible to the eye) but lux go up.
I was expecting more, still this is what i got:
Around 44k lux @ 1 m in max
Not satisfied, and wanting to make better I added another lens.
Chose one to not make UF way more bigger and making attention to preserve dimension as much as i can i chose one lens as u see in photo. Diameter is 40 mm and almost all is used for projecting light (38 mm real diameter used ) . I get an mini drill and work to make an holder for the lens.
It come out good and i am satisfied by overall look and how strong it is. To protect the lens got this and cut it.
The numbers:
From 44 Klux go up to around 65~70 k lux, but the biggest gain was the shape and the clarity of the projected led. The original one is not so good at the quality of projected image, don’t know i got an not so good lens or just this is the ordinary quality of the lens in the UF-T20.
Still i wanted more so of course go dedoming. Chose gasoline dedoming method, and after 3 or 4 hours of waiting the dome almost fall of. The impatient person in me than took a small wire and push it with caution. Lucky all went good this time.
Put back in flash and its alive. Tint go yellow little bit (I like it personally) and measuring lux go:
110 Klux @ 1 m
Waiting for good parts to come (If they don’t lose somewhere!) for now its impossible to improve more .
