EastwardYJ J06

Yes - when i first got into lights, all the LEDs were mounted on 20mm stars and almost all of them had screws holding the star down. This is the firs new 20mm star I've seen in over a year.

But back then you didn't get 20,000 lux at 1m out of anything you could carry.

Which was better with grease or without grease?

Lovely flashlight design. I wouldn't mind one but it's around 4USD above my limit (defined by customs).

I would love to hear about it some more after you rebuild it properly. It has potential for good heatsinking i guess.

Coated lens?

Did i say that is looking very good?

Added to my Wishlist. Thanks for the review Don.

Only with my fingerprints :)

Took it out to check and it seems to be plastic. Time to check if KD has one in this size. It appears to be 36.6mm in diameter and 1.5mm thick. KD don't have anything suitable and flashlightlens.com who do want $5.25 for one plus probably twice that in shipping. Not worth it for a $30 light.

I pulled the screws and there is definitely heatsink compound under the star - it is now all over my fingers. And I forgot to mention - it has a forward clickie which doesn't make sense to me in a multimode light, but it has one anyway...

Some folks will love this, some, like me, would prefer a reverse clicky.

Obviously it wasn't obvious as I thought , sorry how2

Better with compound since his function is fill the small, very small only , air gaps due imperfections , scratches and such between the surfaces of the star and the pill...with a very good work there can be achieved a thermal resistance of 1 C/W , that mean in a 5W powered emitter 5 C difference between the star and the pill , a lousy job as with that Chinese or not glue could result in a thermal resistance of 2 or more C/W with the result of the junction of the mentioned emitter working at more temperature than necessary.Polished metal with metal ( screws the best) and a tiny layer of grease is the way.

Ok, that plastic lens led me out until other torch show up,too bad the lens are only available at that paypal' hater guy, his shipping cost are not outrageously expensive by American standards if you order more than one lens but he want CC pay, no thanks

Also his contact information is a kind of 'watch out ! we want your money not your problems , check the info provided you lazy idiot !

They have 36.7mm x 1.5mm plane glass lenses at DX, you do have to buy 10 though it seems - $3.45 for 10.

Great and informative work as usual, Don! (May I dare add that your reviews were the main reason for me to come back to this place again and again before I finally signed up)

I have some of these DX 10644-lenses left as I bought the 10-pack needing only 1 because it is my belief that no flashlight should be left with a plastic lens. That said, I would happily send you a couple, just PM me!

100%, +1 on that.

Thanks guys!

Nice to know some folk like it. I'll get around to doing a proper review soon on this one. Seems to me it's a very good light.

Me too!

Don,puede con 2 16340?veo la cabeza con muelle de contacto,para 18650 no lo suelen llevar,4,2 o 8,4?gracias.

No hablo español así que esto es de Google Translate. Espero que tenga sentido ...

Con dos barato (de marca WF basura) baterías CR123 (6V) es mucho menos brillante que con un 18650. También parece ser casi imposible cambiar los modosde 6V. Con dos RCR123 protegido, es tan brillante o tal vez un poco más brillante que con un 18650. Pero no hace una gran diferencia, pero me imagino que el calorva a ser peor y tiempo de ejecución más corto mucho.

Or in case Google Translate has done a bad job,

I don't speak Spanish so this is from Google Translate. I hope that it makes sense...

With two cheap (WF brand rubbish) CR123 batteries (6V) it is much less bright than with an 18650. It also seems to be nearly impossible to change modes with 6V. With two protected RCR123 it is as bright or maybe a little brighter than with an 18650. But it doesn't make a big difference but I imagine heat will be worse and runtime much shorter.

Huh, pretty impressive job there from Google Translate. Perfectly understandable translation in Spanish albeit a bit literal.

:) YES,Tiene sentido,very thanks Don.

Hey Don,

I think I have the YJ J01 on order. Glad to see this review. I can't wait to get the flashlight in the upcoming month(s). LOL

Does this light use flat top or button top 18650s?

Most of mine are button top but with springs at both ends it ought to work with both. I'll try a flat top now.

Works fine with a flat top as well.

Thank you for checking it out. Time to order some button tops.
