It can tweak to Duv as well and even adjusts based on LED age (by detecting fwd voltage) to maintain 1 step eclipse. It can dim through wireless commands or via in wall dimmer which detects waveform.
I love improved tech, but this sounds like it crosses a line into overly complex.
Are there any R7S LED bulbs worth recommending?
Interesting name. Feit. Fate. Ill fated? :person_facepalming: 
I’ve really been out of the hobby for lack of time since early May… Just moved into a new house and as any true lighting snob would, despised most of the bulbs/fixtures currently installed. Really wishing a truly good and affordable bulb becomes available soon. I still have a handful of Great Value bulbs waiting to get emitter swaps with SunLike 3030s. Also have really been desiring a truly good variable CCT (but not RGB) bulb. Ideally a smart bulb (circadian) that has a time/calendar/latitude programming maybe via BT or even one-time flashing via USB…
Gave the 600 lumen version of these a try, and it seems to have mad tint shift. The edges of the beam are outright orange on this set of them. I’m also getting more glare than I expected, but it might be just the beam being a bit narrower (36°).
That being said, found a 3000k Luminus 50W equivalent dimmable 90+CRI 40° GU10 claiming 71 lm/w (as opposed to the 80 lm/w that the 600 W Ledare claims) that seems to be pretty good.
Not seeing it online, but the model name in-store was Luminus Elite+ LED.

I’d be very interested to hear more about these StarLike bulbs. Is this the next evolution of your SunLike bulbs? Still using the Seoul/Toshiba SunLike 3030’s/COBs?
Lidl have some E27 2700k 806Lm bulbs £3.49 for 2 pack. They are advertised as Ra >=97 but they are just an awful yellow hue, not the normal white/orange but more a bright yellow colour.

I’d like to make a web app for this list that is a searchable, filterable list and includes spectrum data/charts. Right now I’m using the X-Rite Colormunki Photo, but I’d really like to be able to chart beyond 730nm. The much more expensive Sekonic meters only go to 780nm. The only competing product I’ve found that goes beyond is an aliexpress find for $1550 called the Hopoocolor OHSP350S that covers 350-950nm, or they have an integrating sphere setup with sensors that cover 200-1100nm, model HPCS6500, for the low low price of $7k.
Any options that I’m not aware of that would allow accurate, repeatable capture beyond 350-750nm?
Sekonic C-800 owner here. Even the best LEDs emit practically zero red light out at 780nm where the meter’s chart ends. And a Google search says human vision drops to zero well before that. But the good new is my bill for consultation is only $3500. You saved 50%
Light outside of 350nm-750nm range is practically invisible to humans. For example, 730nm red light is 117x dimmer than 660nm red light for the same output.
Why do you want to do this?
Horticulture maybe?
It looks like the photosynthetic response and far-red horticulture stuff is within the human visible range too.
I just bought some Quasar Science bulbs from their clearance sale. Here are their measurements:
| Quasar Science JDR light bulb 2000k 25deg | 2101K | 0.0026 DUV | 96.9 CRI | Blue light relative amplitude 0.06 | 79.7 R9 | 96.1 R12 | 90 Rf | 94 Rg |
| Quasar Science JDR light bulb 3000k 25deg | 3061K | 0.0035 DUV | 97.1 CRI | Blue light relative amplitude 0.39 | 84.3 R9 | 84.8 R12 | 95 Rf | 99 Rg |
| Quasar Science medium base filament 3000k | 2766K | 0.0003 DUV | 96.8 CRI | Blue light relative amplitude 0.35 | 80.6 R9 | 84.6 R12 | 93 Rf | 99 Rg |
| Quasar Science medium base filament 2000k | 2091K | -0.0009 DUV | 96.1 CRI | Blue light relative amplitude 0.13 | 74.2 R9 | 90.8 R12 | 93 Rf | 101 Rg |
The JDR bulbs have positive DUV resulting in a yellowish/greenish tint. However, the lens can easily be twisted off to insert a sheet of Lee Minus Green Filter. A very easy fix. The filament bulbs are pretty much tintless, though I prefer a negative DUV which makes white appear whiter.
The Hopocolor OHSP-350UV has the widest range I’ve ever seen for hand held spectrometers. Can be had for about $2k
Any experience with the brand? Looks good on paper, but I’m a bit cautious - at the very least I wouldn’t want to compromise the validity of my 350-750 data for sake of wider range.
To reply to the others mentioning the lack of visibility of the light outside of that range:
The first thing that sparked my curiosity was my effort to simulate the look and feeling of sunlight throughout a sunrise. The intensity of sunlight’s output in the 700+ range only continues to grow, and I have to imagine that this could in some way contribute to the quality of life improvements vs a white LED that drops off quickly after 680nm. As deep/far red LEDs become more common, being able to test in that range gets more appealing as well.
Also, there are both benefits and dangers as you get into the UV spectrum as well, and I think it’d be valuable to know what these products are emitting, especially for home lighting.
Just my $0.02 USD.
As I understand, you are searching for rogue wavelengths emitted by cheap bulbs. Unless the bulb is based on a UV emitter, you aren’t going to find any. You see, with LED technology, it’s just a single, 460nm (blue) LED emitter, dusted with a chemical cocktail that causes a conversion of blue light to a whole rainbow of other colors. Check out these readings from these 2 LED bulbs, one cool-white, and the other warm-white. The differences are just in how much blue gets converted by the coating.
To convert to anything outside of visible, would only dim the bulb. And home-lighting bulbs already operate at far lower output than the sun. To re-create that ‘feel’, you only need to buy heating lamps. A UV one and an IR one can be added to any room to give you the same warm feeling as the sun. Of course it comes with all the dangers of unseen radiation, as well as a power bill to boot.
Can you measure % of pulsation of these bulbs ?

About discounts for MASS models
It was the reason why I created it
I think maximum discount will be 20-25% (with 6$ international shipping for any order) and will seems like that: 5+pcs = 5% discount; 15+pcs = 10% discount; 30+pcs = 15% discount; 50+pcs = 20% discount; 100+pcs = 25%
Wholesale price will be about 50% (without shipping)
