[review] Wurkkos WK30 white/red/UV light

It looks like the bezel screws off, the seam being between the switch and frying-bacon symbol.

Might be glued. I tried getting it off for a peek, but didn’t try very hard.

I used a heat gun to bring the front bezel ring up to about 60 Celsius but it still didn’t budge. If it’s expoxy then it may need go hotter, or maybe it pops of instead of unscrews but I’ve not been around any x-ray machines last little while so dunno.

Nice find Lightbringer! It’s a very handy utility light….

No worries. It’s part of my daily rotation now, too. :laughing:

Same here.

Boy, If they knurled this little guy…I’d have to get another one. They’re that neat

What about that grippy sandpaperlike stick-on stuff like for slippery steps? Someone was using that for grip (fiik what it’s called, though).

yeh, think they refer to it as “skate-board tape”……it works….but still…knurlin would be da bomb. :slight_smile:

Just goggled it on Amazon, yep, “grip tape”, fancy colors for skateboards.

A splash of red might look nice, though. :laughing:

hi, they are same cells inside, we just add a white cover on it as we did for other batteries before

It is a point, 365nm cost more, may upgrade in the future

@Lightbringer

awesome light, great find! thx for the review! I have to try to get it over here in Europe.

Like this light a lot. Thanks Lightbringer for reviewing it. Managed to open the bezel with 2 strap wrenches. No heat and just enough force. Seems regular glue was used so a little heat should help. I’m still debating whether to replace the main LED with 4000K 351D and the red to a 2200K 351B. I really don’t like red led but might need it someday.

I thought my desire for this light will pass as time passes by.
Unfortunatelly not.
I’m too weak to resist. Ordered. :person_facepalming:

But I don’t think I’ll use red light. I’ve read aswang has changed the red led to other. Hence my question: what instead? I mean which footprint (edit: figured 3535), voltage and amperage should I search for to replace this LED? I think I’ll go for some warm colors, 3000-4000K. Or 5000K but as a thrower, so without dome.

Any ideas which LED could succesfully replace the red one?

You could swap the red one by a Samsung LH351B 2.200K 80CRI oder LH351B 3.000K 90CRI if you like incandescent light.

2700K SST-20 from KD is quite nice with BBL and below tint. If you want better throw and more lumens but lower CRI there are 5000K or 6500K SST-20s or maybe a dedomed xpg or xpl-hi. Its a small reflector though so don’t expect a lot of throw. I measured tailcap current for different modes with a regular multimeter.

White 0.01, 0.27, 0.88, 3.2 A
Red 0.02, 0.22, 0.84 A
UV 0.03, 0.5 A

So basically red has low med high and no turbo compared to the white led. Haven’t swapped mine yet since I realized it’s my only light with red led on it.

I’m actually tempted to put 5700K, 4500K and 3000K 219Bs in it. Damn. Now I’m tempted to buy another one.

Another purchase is totally justified considering you’re a flashololic :smiley:

So if there’s less Amps put in red LED, should I take something specific into account? Lowest Vf? Fewer Amps recommended by manufacturer? How about XP-G2 dedomed?

LH351B 3000K would be lovely to have. But living in Central Europe it’s hard to find one. As well as 4000K since L4P is out of stock…

Move the 351d to where the red one was for flood and the SST20 to where the 351d was for better throw. Then change the UV to 365.

You could replace it with a second white LED, remove the wire, and bridge it to the lead for the first white LED to get more output on all white modes - the red mode just wouldn’t do anything.
