Q8 modding

ok so, update… ordered a new driver, MCPCB and 8 of the Samsung LH351D 4000K 90CRI…
shame i coulden’t use the N219s but… live and learn, right lol
tnx everyone for the assist, i’ll update again once the new parts arrive. :slight_smile:

:::Edit::: On another note, has anyone dedomed a Samsung LH351D 4000K 90CRI yet? If so, resaults?

Not dedomed, I sliced a few. After slicing close to the phosfor I sanded the surface with very sand paper. The result is 20% light loSs, 3400K end colour temp, 93CRI and a very very good tint. The 20% loss is more than average, I wonder if it would be less if I did an even better polishing job.

Awesome, tnx… how was the beam pattern? was this on a single or multi chip light?

Single emitter lights, the beam is very good. The only big disadvantage is the light loss, the lh351d is found to be a realtively efficient high CRI led, you loose that advantage.

hmmm, ok…. well i bought enough to do a few mods so maybe i’ll exp with a couple. maybe a whitegas dedome.
tnx again

Anybody measured cd with xpl HI and spring bypass??

What is the recommended method for Q8 spring bypass when the light is used reasonably often? I just added some solder blobs at the top and bottom and ran short 22AWG leads between them.

That’s all you really need. Some wire bypassing the spring nothing special.

My Samsungs came in so here’s the pix….

Fence is 100 FT away. Camera settings are locked all around.

Q8 Samsung LH351D 4000K 90CRI

tnx jason!

Samsung LH351D looks very nice!

They really are! in person, even better, might be the best LEDs i’ve seen thus far.

:person_facepalming:
And I bought only 8 of the Samsungs

:smiley: Thats exactly what i said after i installed these on my Q8! “Damnit, i on;ly bought 8???”

Did you bridge the feathers on your Q8 with Samsung Led?

beg pardon?

I think ‘deus1ex’ is asking if you’ve “bypassed the springs” on your Q8 with the Samsung emitters. :slight_smile:

Ah! TYVM!
& yes, both lights are bypassed.

Yes that’s what I meant. Thank you
