[Optisolis/E17A/E21A] Jetbeam Jet-µ

I tested a couple Jetusolis. The 5000K ones were very tightly grouped.

That does at least confirm my subjective impressions that it was a little cool of 5000k. I actually prefer that, as it puts it closer to sunlight than not.

Overcast day, so can’t compare patches of sunlight to the Optisolis yet. :frowning:

Got a chance to compare the 5k Optisolis to midday sunlight. Tested on red bricks, mud and leaves, bark, white printer paper and much more.

The optisolis is slightly warmer, which is a given, but it is definitely slightly greener than sunlight to my eyes. I will put a filter on it.

So far I only hear excessive green tint Jetusolis from you. I think Jetusolis is not the right choice for you. Better go with JetuE21A for more traditional and well accepted tint flavour. I can upgrade it to JetuE21A if you want. PM me if you’re interested.

Thanks for the offer. It doesn’t take much to put a filter on it, and I like the idea that the Optisolis fills out the cyan region. I ordered the Optisolis just to have a benchmark for this kind of ultra high cri lighting. I don’t think the lee filter will degrade the cyan part of the spectrum.

I already have my ROT66 219B SW45K R9080 and ROT66 SST20 4000k + 804 filter for pretty lighting.

Got mine Jetusolis P9 5000K :slight_smile:

Here is beam shot of: Jetusolis 5000K (right), E21A sm503 (left), Sofirn C01 Yuji 5600K (top):

I was curious, so I ran this image through my color-averaging brightness-normalizer script. It makes each individual pixel as bright as possible while staying true to the original tint, which makes it easier to compare tints.

I know that this is mostly a tint snob thread, but I would also like to praise the choice of the host. This tiny twisty is incredibly handy an the beam profile from the e21a/stock tir is incredible. My wife who really hates all and each of my flashlights, just took this one from me and uses it daily.

Just wanted to share a useful mod of my e21a version.

I replaced the supplied TIR optics by an aspheric lens which I extracted from a cheap ebay aaa zoomie called skywolfeye ($2.99 or so). Had to trim the lens a little bit but it is almost the right size. Will need to blacken the white gasket to completely eliminate the stray light, but even now I have a great uniform circular beam. An aaa version of McGizmo Sundrop. Very happy and will order some Jets with higher cct

Received my 2700k and 5000k Optisolis JetU from Maukka a few days ago. It is actually alot brighter than I expected for Optisolis and AAA. Way brighter than the Sofirn C01 and E01vn. R9 appears a slight bit higher than the Yuji but it’s hard to compare 90+ cri emitters. Personally I still like the E21A 9080 more because the tint is much more rosy. However, the Optisolis is more of a sunlight simulator. I find the 5000k Optisolis tint and color rendering about identical to daylight on a cloudy day.

This is why I only use cool white high CRI for working (cooking included). Especially for cooking, warm white just doesn’t work for me.

Bachelor’s favourite breakfast, in this case it’s my brunchner.
What are they: new palm cooking oil, freshly cut potatoes (unpeeled), fully submerged in deep a fried pan (~150-180°C) for about 10 mnutes, 2pcs Bernardi chicken sausages (12cm each), Ayam brand canned beans in light tomato sauce, freshly ground black pepper and some salt sprinkles, Maestro mayonnaise mixed with French’s mustard sauce (Added them later). Usually I use fresh half cooked fried mushrooms chops instead of canned beans, but ran out of them.
Served on my mom’s porcelain plate she bought in 1955.

It’s just a smartphone camera, mind the quality (and slight glare from the oily lens)

During kitchen work, I mostly use my 4×sm503-D220-L2 modded Skilhunt H03 headlamp - it is especially useful, when I want to determine, how mildly I want to roast/fry sliced onion on oil.

It is actually a very interesting point. Generally, I would agree with Clemence that, the “natural” tint would be the 6500, which is pretty close to that on overcast day. But on the other hand, the most important thing with cooking is that the cct is consistent over time. So if I for example have cooked under incand lights only for years, I d rather not go to a very different cct

so would E21A cooking look too “Clinical” - maybe?

Darryl, it’s not about the looks. It’s about how I can judge if what I see is correct according to my memory set. Cool white has the most complete spectrum coverage with higher average peaks.
If an object can only reflects certain wavelenght it will looks black in the absence of that particular spectrum. For objects with wide wavelenght reflectance, different spectrum ratios will shows different colors too.
A good example is blue color in nature. It’s very rare because in nature, blue is the combination of several different reflected wavelenght. There’s a rare blue winged butterfly with prism like micro scales that makes it looks blue. The individual scale itself is actually colorless. Polar bear hair is actually transparent too, not white.

The food picture is making me hungry.

First picture look like a good picture. But second picture, I can feel that the plate is right in front of me.

There’s more, wait…. let me finish my cooking first. I will have baby fishes for my dinner tonight. Stay tuned (hungry)…

[Clemence]

OK, here’s my dinner’s menu today

Tenggiri’s (spanish mackerel) eggs, fresh chopped button mushrooms, (accidentally) freeze dried garlic, oregano and salt sprinkles. All sauteed in pure coconut (not palm) oil for less than 5 minutes.
Then served with multi grain rice (normal rice + a little Kongbap mix) and snake fish floss for a little sweetness taste. Cheap, easy to cook, and satisfying. I tend to add as little as possible seasoning to keep the original taste of the ingredients.

It tasted sooooooooo damn good! Especially after a full week unable to eat properly (only slurry foods once a day). I had severe toothache from a not-so-wise wisdom teeth inflammation. I had it removed two days ago. Supposed to do it 30 years ago.

EDIT:
Conclusions:

- If you don’t have high CRI lighting, then warm white does a better job than cool white

- If you want to “mask” the appearance of something in your food, warm white can do it

- High CRI cool white while not too pleasant to our eyes in the long run, is very beneficial for chefs. Serving them under high CRI 5000K - 6500K will shows the true colors of any “colorful” foods.

  • warm white ambient lighting with high CRI cool white table lights can be used to preserve the cozy environment while having an inviting meals.

Happy drooling…
