How do you feel when you got some USD40/pc worth UV LED in damaged condition?
In my case, I'm happy ^:). But still complained the courier
Some of them are perfectly dedomed. Otherwise I wouldn't even dare to try it. The lens is only glued to the base at four tiny points (yup, not airtight at all)not poured over like common LEDs, now I know. So, with the air gap in between, dedoming this one should yield a bithigher luminous output and floodier emission. Now we have option right from the chip scale, nice.
These are the new NVSU233B-D4 365nm not yet launched, not even on the website. The die is different with larger uninterrupted emitting area. The 365nm said to perform up to 1400mW (previously 1030mW). For those not familiar with this one, you can check the older model test and detail here: https://budgetlightforum.com/t/-/44419
I will test them ASAP, in the meantime, enjoy the phreakview below:
@Djozz: you'll get the NVSU233A-D1 and NVSU233B-D4 soon. ;)
Anyone interested? I have 5 pcs free (you pay the shipping of course) samples to share. POST your interest in this thread
Sure, but I will need to check them first. Especially those with fell off dome, if they’re still working or not. So, expect to get LED with solder marks
I’m honored to get these premium leds from you Clemence. I’m well behind in testing them, but still excited by the developements.
The pattern of die of the D4 has some resemblance to the newer LG Innotek UV leds. Would like to see some of those in action too but they are impossible to obtain.
Did some photos with my reverse adapter for DSLR
Used Canon Eos 50D with 16-35mm F2.8 lens
@F=18 and reverse adapter ISO400 1/160s
light with a 1400 lumens 5000K NW flashlight from the side
Then I ordered a cheap macro extender for EF lenses
dismantled it to get the Ring connecting to the lens to the camera
on the other side I removed the contact plate
I used a cable to connect the both contact plates
Then I dremeled the mechanical reverse adapter to make the contact plate fir and hot glued in there
