COURUI DO1 'Big Head' (Black/GRAY NOW AVAILABLE) $29.99 @ Gearbest ( use coupon: gbcourui) A long-throw modder's light!

An XP-L or XP-G2 dropped in there would bring a tear to my eye!

EDIT: Thanks, btw!

Yep, stock it leaves a lot to be desired but it has the potential to do some big numbers once modded :smiley:

Great price and thanks for organising this awesome coupon tatasal :wink:

EDIT: Fixed it for ya :stuck_out_tongue:

Thanks, but actually this not a GB or group buy, as no minimum orders are required anymore… Can be ordered now.

Thanks for posting this deal Tatasal

I love this light! It’s one of my favorites to mod. I can crank these up to stomp on a stock TN32. They are OK stock but modded they are fantastic. I’ll be picking up a few of them if I can get some other lights sold.

If anyone out here needs help modding one feel free to ask me how or you can always have it mailed to me for modding and we can work something out that way. This is a deal that really shouldn’t be passed up. In my opinion this is the best budget thrower around in this size of a light. It’s not pocket sized for sure but if what you want is a spotlight this is it.

I have been wanting to have this light for months now. I m hesitant though because of opinions like the one above. In terms of brightness and/or throw, can anyone comment on it’s performance vs other stock lights like

a. Small sun TY-08
b. HD2010
c. Convoy L4
d. XinTD X3

To mod this light can the existing driver be used or does it need a driver swap?

TY-08 is driven at a similar level, but has smaller reflector.
L4 & X3, same story, but smaller again.
HD2010 - If you scored the good driver & used good cells, it may be close between them.

Well you can just put in an XP-G2 on a noctigon and get really good throw out of it. It takes a bit to get it to focus correctly but it’s not too hard. Cereal Killer has a driver that will rock it out if you want to put your XM-L2 on a noctigon.

I tried to mod the driver on it but I didn’t have any luck doing that so I swapped mine out, I have done a few of them now and they are really nice.

This light is on my to-buy list. For under $30, I’d take it over T08 or HD2010 anytime due to its 3P battery and superior reflector.

How long will this deal last?

Whooho, I’ll be having mine shipped directly to you….soup it up buddy!

The HD2010 is not an easy mod. It will take quite a bit of effort.

Not sure about this baby.. but I hope it will be easier, as I am about to pull the trigger.

Dora’s gone for home, perhaps tomorrow we will know the answer. Thanks

Just ordered another - my excuse is that I don’t have a black one yet… :beer:

I am going to order one at this price, with the tracking number as suggested of course

The disease is getting worse. :wink: I thought I could hold out for the BLF Edition GB light. But, in a moment of weakness, I bought this light. You guys talked me into it! That’s my excuse when the wife asks! :stuck_out_tongue: Anyway, I’ve just made my first purchase from GB. I paid the $1.99 extra for tracking, as per the advice given in another thread. :bigsmile:

I thought Courui releases another new thrower by reading the title… this is actually the one some of us have bought previously, but not at the price as good as this of course. Thanks tatasal for bringing this deal up.

Driver
The simplest way to bump up the current of this light is by removing the R120 resistor and bridge across it. This way it gives you near direct drive on high mode. But I have an issue by bridging the resistor, when the light is turned off the LED still glow dimly. I used a crappy soldering iron to do this and I suspect the driver was damaged so do it with care and good soldering iron guys.

LED
Since there is 26mm Maxtoch DTP board available it is advisable to use them so that the soldering joint won’t interfere with the big flat reflector bottom. I used 20mm Noctigon back then and it is a pain to make the solder joint really flat, and still not ideal.

Noctigon and Maxtoch boards are thinner than the stock aluminium board, so you should add additional copper sheet under the DTP board to increase its thickness, otherwise the reflector will be too loose inside and cannot be screwed down tight later. If you don’t want to reflow additiong copper sheet underneath, the alternative way is by unscrewing the pill by a few turns to raise the position of the LED, but this will leave questionable heat transitiveness to the flashlight body, not sure about this and it’s up to you. You may add copper sheet under the pill to solve this though.

Lockout
Since it is electronic switch some people may want to find a way to make it able to lockout. It is doable with janko.hrasko’s method .

Since I wasn’t familiar with this light before I have spent a lot of time trying things and kind of mess the light up. I have lost interest in it already and I might want to let it go to somebody else.

Just wanted to let people know I’ve so done a few of these for customers and am more than happy to do others.

I have 2 on the way (unfortunately only one from GB, I ordered another @ full price about 2 weeks ago from AE).

What’s with the half drilled hole under the button? Needs drilled out for an indicator.

+1 The HD2010 is a beast to focus properly with a dedomed LED.

Thanks guys for sharing your comments/experiences with this light.

@ cereal_killer: If you have a link, you may post it here.

Again, that’s true BLF spirit right there.

Thanks a lot, I waited forever for a good price on this. :bigsmile:
