4 Cree Light !!

[Garnett]

Mine doesn't.

My Romisen RC-T5 operates as follows:

Click -> 100%
Click -> Off
Click -> 50%
Click -> Off
Click -> Flashing
Click -> Off
Click -> 100%

and so on.... If I leave the light off for more than a minute, it starts over from the beginning just like above, no matter what was the last output level.

Same here. Also, I left mine on, on LOW for an hour (with 4 RCR123s) and never experienced any flickering (although rather than watch it for the hour, I just revisited it every 10 mins or so)

I really rate the torch personally.

 

[batvette]

It's a 3-mode light.
According to batvette, it starts with low.

FWIW in my running on I wasn't clear, I was commenting on DX's MXpower 3 cree which appears to have the same tailcap 3 way clickie, though of course it may not be. If it were I thought it may be the source of the poor performance.

As for the UI of the mx, I think it's low strobe high but I'm not sure, every time it's like playing the lottery.

I'm waiting on the Romison. I'm under the impression it will be about 1 led brighter than the MX with less throw. Brighter=good. Just in case we forgot why we're here.:wave:

mx power 3 cree is a different tailcap. can't be swaped. the brightness is not as bright as I wanted. only 23lux for the mx power compare to 26lux for T-5. the T-5 is driven at lower current as same batteries last longer then in the wf500, which was bright at 26lux 3 cree, but burn out in 10 minutes.

so you also have the MX power 3 cree as well as the Romison 4 cree? I just got my 4 cree in today, and am a little underwhelmed, it it no brighter than the MX and the tint, sadly, is the pukey yellow green that has infested about 20% of all the star-emotter lights I have ever bought. (of course only noticeably annoying next to a good tint light. )

I might even say it's a little dimmer than the 3 cree. To its credit is feels more solid, but heavier. Much more comfortable form factor with 3 rcr 123's but flickers right off with 3 RCR123's hot off the charger @4.2v ea. No flicker with 4 batteries.


In the same shipment I got my glass lens for the MX, and a single cr123 cree "romison rc-c3" which is a little bigger than its ultrafire cousin I've had for a while that gets way too hot to handle. The romison is equally bright and runs cooler but also suffers (less) from the pukey tint.


I should have just spent the buck and change on the lens and passed on the rest.


So my subjective review on the romison 4 cree reads like this:

Buy the MX power 3 cree and sent it to me (so I can have a 2nd) and I will mail you back a light nearly as bright, heavier, longer, with a smaller head, that looks a tad bit classier in finish, and I will try not to get any vomit on it looking at the beam as it goes in the box.

Oh and you get a holster too. I never wear a belt, one of the small perks about watching you don't overeat. Maybe its the color of the beams.


FWIW shipment was well packed and for the first time after 3 orders from Hong Kong, (2 DX, 1 Kai) ALL the RCR123 batteries work. (this time was 6 rcr123 unprotected, 800ma) Rechargeables rule! They rule! I.... am the great..... corn- oh, never mind. I'm 45 fer chrissakes.


In the end, you cannot follow "great" with "good" without some regret. My T-5 is "good". Well except for the pukey thing.

:wave: Hi, this is my first post here. I'm from Sweden so english is not my language.

I've red about put the LED's from 2x2 in paralell to 4 in series . Is it possible with the orginal regulator or am I forced to change the regulator too?

 

[fa__]

It's possible with the orignal regulator, but you then will have to use 4*123 to get a high enough voltage. In the long terme, the regulator heats a lot and will shut off until it cools down ... so in reality you should replace the regulator

 

[Xak]

The ETA on my T5 is 2/25!!!

 

[jims]

Can you recommend a regulator for this light? Preferably something the same size.
Thanks

 

[Vermonter73]

They sent an email today that mine has shipped....again.

Even if the electronics turn out to be a dud, the 4-Cree head will be perfect as a bike light with all the spill.

What is the dimensions of the regulator used in this light? I have some work in progress here, or you could use this driver with some modifications (but with no "multibattery" - only 2x18650, or only 4xRCR123A).

 

[jims]

The original regulator is 20 mm in width.

for those you their t-5 order got backorder have it lucky, the new one that I got was 4 white len cree led instead of my 3 week old yellow len led t-5. when I installed the batteries, they were very bright. much brighter then my old 3-week old T-5. I test them to the lux meter, yeap, the old t-5 read 14.8lux and new white len led read 19.2lux( 27% brighter). dealextreme doesn't mentain what led was used, so I can not return them for the white Cree. I think these white led are really Q4 as in their Romisen website then.

 

[deathkenli]

I got mine this noon.
There is only one word to describe it: BRIGHT!
BTW, those CREEs on the RC-T5 is different from the one on my RC-F4, bare metal base on T5, yellow phosphor coating on F4.
I ordered a grey T5, but DX sent me a black-grey one. Didn't bother to return it, I'm not picky about color anyway.

 

[dda]

No yellow phosphor on the LEDs? What are they using, nanocrystals? My T5 has yellow phosphor and is also very bright.

I said "metal base", not the die.

 

[Fubar411]

So is this the best bang for the buck LED flashlight that takes 2 18650 batteries? I don't care for multi-mode, I might just bypass it if possible.

 

[eddielee70]

old 3 week T-5 have this color of led on:
http://www.kaidomain.com/WEBUI/ProductDetail.aspx?TranID=3293

new T-5 that just arrived 3 days ago that is 25% brighter had the white background led.
http://www.kaidomain.com/WEBUI/ProductDetail.aspx?TranID=4076

don't know the if it's q4 or not, but it's 25% brighter with lux meter. you figure it out.

 

[Xak]

Mine is backordered with an ETA of 2/25. Think it will come with the brighter, clear LEDs?

Is there a difference in runtime between the two different RC-T5 lights you have?

Hi

RC-T5 4xCree

Yellow Base Cree -
2x 18650 = 0.7A
4x RCR123A = 0.58A

Silver Base Cree -
2x 18650 = 0.8A
4x RCR123A = 0.57A

Yellow


Silver


With the yellow ones the yellow coats everything internal - including the four little connector wires . . .

The Older Yellow base version seems to have a poorer driver that underdrives when using 2x18650 cells and is noticably brighter when on 4xRCR-123A
