[GB ended,discussion only] CRI > 80+ NICHIA 2000K-6500K [E21A/219B/219C/319A/144A/757GT-F1(Optisolis)]

I just received the 5 Tiara C1 Pros modded with 4x E21A from Virence.com and I am very happy with Clemence’s work! The packaging of my emitter/mcpcb order was phenomenal too! :+1: :beer:

I love the E21A tint especially the 2500k and 3000k version, which is perfect for bedside use. They are rosier tinted than the 3000k 9050 219B bedside EDC I’ve been using, which I already thought looks really nice. The 4000k is slightly rosier looking than my 9050 219Bs but not as rosy as the Cree 5D tints on the Emisar lights. However, it looks noticeably cooler than the Cree 5D tint. I think the 219B 9080 will be even better looking tint wise if you prefer rosier tint. I took lumen readings at 1sec (turn-on) using the TA Tube calibrated with Maukka calibration lights:
Tiara C1 Pro 4000k – 572 lumens
Tiara C1 Pro 3500k – 539 lumens
Tiara C1 Pro 3000k – 529 lumens
Tiara C1 Pro 2500k – 438 lumens
Tiara C1 Pro 2000k – 407 lumens

Lights were running with fully charged Aspire 18350 1100mah batteries. I doubt it matters what batteries I use though since the amps are pretty low. But the output is quite impressive given how small the Tiara is and how good the tint and CRI looks. Keep in mind these are true calibrated OTF lumens, not manufacturer over inflated lumens.

@ SKV89, I love that you ordered 5 of them each with their own CCT.

I have one in 4000K and absolutely love the tint and color rendering. Best I have seen to date!
Which TIR optic did you end up using on the lights? Did you have them painted white or did you leave them as clear?

Last but not least, you will need to let us know which “flavour” / CCT you like best.

Thanks @SKV89, we’re just calibrating our light box/tube at once. I used Djozz’s calibrated S2 for my light box reading which is actually about 7-8% higher than Maukka’s number. Enjoy the lights and I will send you the rest of the missing items. That was a super busy and hectic time for me, sorry about that.

Yep I got the Virence.com discount applied for larger purchases :smiley: I wanted a set for comparison purposes.

I think Clemence used the 120deg. These were painted white for max ouput.

I like 2500k to 3000k for night time bedside EDC. Good for use as ambient lighting while watching TV in bed too. I’ll be alternating the 2500k and 3000k Tiaras for this purpose to see which one I like best.

I like 4000k to 5000k for day time work use. My favorite tint so far is the 219B 4500k 9080 on the ROT66. A huge flood of gorgeous neutral white HI CRI beam. Great for picture taking.

Your lumen measurements are very reasonable. 7-8% higher is very reasonable considering manufacturers ratings are easily 30+ % higher. No problem and no rush with the few missing items and thanks for including bonus gifts! That was a difficult order with so many different emitter configurations. Thanks for you hard work!

I’m thinking for my next light to use the 4500K E21A, but now you have me thinking about a 3000K as well!
Are the moonlight modes still moonlight with the painted white optics?

Enjoy your new lights! :slight_smile:

Regarding E21A emitters, approx. 2 months ago a shortage of some CCTs was announced by Nichia, because of issues with mass production.

Clemence, does this shortage still persist, or we might expect a restock in some time? I just asking this, because I just started to pick items for a new order, and I wonder, if it does worth to wait a few more weeks, or it would be better to proceed with my current order. (I would be interested in 3000K E21A - but would be happy to buy other CCTs not currently stocked as well, e.g. 2700K, 3500K or 5700K)

Moonlight mode still appears sub 1 lumen.

Any R9080 and above Nichias always have some shortage problem. Those are the least demanded LEDs. Except for the Optisolis which has been a sudden boom in the last few months. Nichia is developing a full spectrum grow light LED with normal tint and CCT as Optisolis. These could be a breakthrough for 24 hours farming. No more crop inspection under funny purple lights. I’ll prepare some samples for Maukka if he is OK to test it for us.

I’m afraid I’m not going to order more Nichias for the next 2 months. Already invested in something else. But who knows if (miss) Santa Claus passes by one of these days.

- Clemence

Sure thing!

:partying_face: :slight_smile:

Unusual CRI rank: Rsp0a
No data available to the public yet.

This is said to be almost similar to Optisolis but with some special spectrum tweaks for optimal plant growth.

- Clemence

Any chance you’d get those 219b sw35k r9080 ones?

Uhm, never know it exist in R9080. I thought only up to R9050

- Clemence

Some guy was selling it on FB and one new special edition HDS will be offered with it.

That sound nice! Never seen them, but I’d be in for that.

I guess I know him :person_facepalming: .
He got those 3500K from somewhere else, not me. I have never interested in 219B series, so forgive my ignorance.

- Clemence

Hmmm… 3500K 219B 9080 sounds delicious… :heart_eyes:

According to LEDRISE, they can still get the NVSL219B-V1 9080 219B from 3000k all the way to 4500k from Nichia but their MOQ is “one full roll”.

What is that something else? :wink: Care to share or is it meant as a surprise for us??
