UltraFire MCU-C88

Just received my UltraFire MCU-C88 from Manafont, and in a standard Manafont manner, pretty fast.

http://www.manafont.com/product_info.php/ultrafire-c88-cree-q5-3mode-mem...

The build quality is very good. Machining and hard anodizing are flawless. The reflector is fairly deep, and gives a very good throw (I measured about 17000 lux/m). This light use 3xAA batteries, and have 3 useful modes (hi, med, low). Inner diameter of the body is 30.5 mm, so 26500 with some adapter should fit inside just fine. I already modded mine with XP-G R4 neutral white, but I think this driver from DX, 3x14500 and XM-L could be a good combination. This light is a really massive, so heatsinking shouldn't be a problem.

That's one solid light. How good is the heatsinking?

 

22mm driver?

 

Looks like a fun light to mod. It doesn't look like it would bore to take a 32600 which would be really nice since i already have two of those.

 

The numbers from my light tests are always to be found here.

Modified that's my pick for  the next blf light  simple and easy .. I think I'm just a little tired of tiny light and wanta something sexy,bright  and interesting , with some heft to it .

extra body tube ,extra AA holders ,xml neutral mildly driven ,a nice low and memory

is it ringy ad would an orange peel reflector  help that ? is the xpg ringy , with a smooth reflector ?

 

more info on this one .. please !!!

Rings are pretty much an XR-E thing. With an XP-G or XM-L, OP reflectors shouldn't be necessary and you'll get more throw out of a smooth reflector.

Looks like a very interesting light , very interesting . 

A few questions ....

1/  How large a base for the LED does it accept ?  12mm  

2/ Current draw 

3/ Looks to be a 17mm Driver ?   

Would have loved to have seen a review in stock form , I think this light is an excellent idea [ 3xAA ] 

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

Thanks for the review. Maybe I should buy one too. I already have 1xAA, 2xAA and 4xAA lights all I need is a 3xAA one to complete the row. Maybe some 6xAA Polestar and an 8xAA TK41 afterwards:)

Some more images. The led base is 15 mm, and KD XP-G R4 heatsink is 13,5 mm, so it fit fine. Yes, the driver is standard 17 mm, and the driver housing is 20 mm. There's plenty of room to play with different configurations. The threads are the same on the both sides of the body, and theoretically it is possible to made one 6xAA light if someone is willing to sacrifice another flashlight Smile

I made a small centering part for XP-G led, because the hole on the reflector is made for XR-E emitter. The current draw on high is about 1 A with XP-G led, and 0,8 A with original Q5.

Nice light, but expensive for something to mod. These Chinese makers need to get over the XR-E lights and move on to XP-G and XM-L's. With a 2.8A driver and and XM-L, you've got an AA-powered light that would just rock. But $28 plus a $10 LED and $5 driver gets kind of steep.

260g without batteries (~150g for the head/reflector assembly). ie the head assembly (less pill) of the C88 weighs much more than most P60 hosts, and nearly as much as a complete C8. The heat sinking is this thing looks capable of dealing with much higher output emitters than the XRE Q5 it comes with, but it performs so well as is that I can't see much sense in modding.

I'm with you there; I bought this light to mod it, specifically to make a 'poor man's Maelstrom' with XM-L and 26500 cell... but this light is too nice to risc messing it up when modding it. It has a tighter and brighter hotspot than my Skyline 2 on 2xCR123!

Dang... I guess I have to get a second one to mod it Wink

If you get two then.. you'll have twice as much fun:p  with 4 battery packs / 2 spares   and  extra body tube and ...

maybe a neutral xml not overdriven 600lm with a sexy tint .nice driver with no disco flash or bad pwm ..

 EDIT :   great light .. time to buy another one.. gonna mod this one to xpg and the second one to a neutral xml and play lego with the two and their parts ..:)

 I like the screen name   you'll like this light it;s a fatty .. it weighs 360 grams with batteries in it .. it's  a hefty beast . I think most people who have it really like it . I 'm sure i didn't know what a real thrower was until I got this light .i'm impressed , looking forward to modding it as well.

Agenthex why did you have to revive this thread I really want this light I have put it in my cart about a dozen times it would be so sweet with an XML driven at 2.8 amps.

I am already visualizing the duct tape over your mouth.

I have modded my MCU C88 with XM-L T6 and NANJG105 driver, great throw capability, just get it and mod to XM-L, sure it will give you a smile Big Smile

this is TK567 and modded MCU C88 beamshot

Well, someone I know wanted a AA light, and I was trying to figure out if this is regulated or not, because the decent 2AA ones kind of are by default since they use a boost driver. It would definitely be pretty sweet w/ xml but they're flashlight noob so prolly makes no difference.

I've been wanting one of these to mod (XML/driver) since the original post. I think It would be great having a 3AA XML light (with the option to pull the carrier and use li-on). Add it to the list of lights I want to get. Smile

There aren't a whole lot of duplicates of this light in your collection

My daughter asked me to provide a thrower for their newly acquired boat. My first choice was a HS-802 (since I like mine), but she cringed seeing the precautions I use when charging my 18650's. "That's not for us", she admitted.

Therefore, based on opinions from this thread, I ordered a C88, which arrived today. Build quality is impressive, from the spotless reflector to the smoothest among non-anodized threads. The clicky feels very nice. Current draw from a freshly charged eneloop triplet (4.19V) is 0.8A.

At 1m, the hotspot is 5cm wide (same as HS-802), but with a smaller corona, no rings and a much darker spill. Thus, a perfect reflector for pure throw. On the other hand, the C88's beam spread angle is larger, with distance the hotspot grows faster, lux falling.

Although the C88 can still bring out a white house at 400m (barely), the HS-802 illuminates it considerably brighter.

I should mention that my HS-802 (R2) is somewhat overdriven at 1.4A from battery (stock), so we are dealing with 75% more wattage supplied, not to mention the higher LED bin. Taking all this into account, the C88 performs great.

Daughter is happy.

Would it be possible to do a quick check w/ some alkalines to see how much they droop (esp. w/ time)?

Ok, here are my results.

Alkalines Duracell Turbo (for toys etc.), expiration 2017, power-pack voltage = 4.82V.

As first switched on Hi                             34600 lux @ 1m
after 5min on Hi plus 5min rest               30800 lux @ 1m
after 5 more min on Hi plus 5min rest    28500 lux @ 1m
after 5 more min on Hi plus 5min rest    27200 lux @ 1m
after 5 more min on Hi plus 5min rest    25600 lux @ 1m
after 5 more min on Hi plus 5min rest    24800 lux @ 1m
after 5 more min on Hi plus 5min rest    23600 lux @ 1m

Power-pack voltage 10min after last reading = 4.23V.

With fully charged Eneloops, power-pack voltage = 4.25V ... 30900 lux @ 1m.

For comparison: HS-802, fully charged Soshine 18650 ... 53000 lux @ 1m.

The actual measurements were taken at 5.0m for the C88 and at 7.0m for the HS-802, always max reading from scanning across the hotspot.
