I am thinking to implement it the same way as there are some options on E27. The downside could be that the light is not evenly distributed as with the integrated LED. I am also not sure how the diffuser will affect the CRI.
Maybe I will conclude on buying some E27 Sunlikes in combination with any of the options above.
For the rest of the installation I plan to buy some GU10 Philips ExpertColor (or Sunlikes on GU10 adapter, but don’t like the adapter idea). Another option is GX53 Sunlike - SunLike5-8 GX53 светодиодная лампа.
I chose to go with Lidl’s Livarnolux for the bulk of my bulb needs. But I have some uses for better bulbs as well, these will be filled by either Sunlike or Bocian.
Below is my latest product (Bridgelux THRIVE 7W GU10 TIR optics) . Sorry, but I am quite a busy man and currently do not have time to translate. I will make a description in free time and maybe send some samples to Maukka https://www.swiatelka.pl/viewtopic.php?f=57&t=25080
The same driver as here but with a higher current set: https://budgetlightforum.com/t/-/51820
Unfortunately, there is very little space in the GU10 mount for the power supply. I like drivers with a power factor correction and high efficiency ~ 90% as been used in this product. There are available small drivers with a fast output 40-60kHz but they have a PF ~ 0.5 and an efficiency between 70-80% (more heat generated in the power supply system = much shorter product life).
In my area the majority of new houses use recessed LED lights with no “bulb”.
I certainly hope there is opportunity for ultra high CRI in this market because it feels like the little guy here is going to have less and less market share as time goes on.
Here is example electrical parameters measurement for new 7W GU10 THRIVE. As You can see there is only 0,85W power wasted on driver heating up. I also modify by myself factory condition drivers by adding NTC thermistor (soft start) and additional capacity on output (low impedance, long life capacitor) and it takes really long years to dried them up till malfunction.
I understand there are a few people with the equipment to test the light quality. I may be willing to send them a sample to test for the benefit of all, as I also would like to have a known good quality light for my photography of artwork.
The short answer is it can be. Led emitters of higher CRI aren't more expensive to develop or manufacture. The actual reason behind low CRI leds still being the norm is because of the race for luminous efficacy, to boast higher lumen figures of “light which resembles white light”. Actual natural white light, as a blackbody radiator or sun's spectra, cannot be obtained with the highest efficacies because it encompasses many frequencies which the eye is not very sensitive to or sensitive at all. High CRI leds' spectra resembles white light in what is considered the visible spectrum (sources: Visible spectrum @Wikipedia, Efficiency of LEDs: The highest luminous efficacy of a white LED @ dial.de), still with some cutbacks.
Concerning the quality of the electronic components in the above lamp or its heatsinking capacity and average working temperature (which impacts lifespan), that is another story.
I just purchased a new batch of this bulb and the DUV is pretty bad. It starts out at 0.0025 and goes down to about 0.0010 after an hour. Does anyone have any recommendations for high CRI GU10 bulbs that are below the BBL?
I solved the duv issue by cutting 1/8 or 1/4 minus green Lee filters and attaching it to the GU10 bulbs with a tiny piece of double sided tape at the center!
I'm new to this forum, I actually stumbled across this place because of this thread.
I did see the beginning of the thread that has a chart with some high CRI chips, I was wondering if there's a list of available US bulbs for home use that have very high CRI, and also if if there's any strips(flex or rigid may both work) that utilize very high CRI chips.
I have a couple projects, one I'm just wanting to update my home lighting because I'm not satisfied with the CREE bulbs(although they are way better than the GE Reveal bulbs they replaced due to terrible lifespan).
The other project is what I need strips for, I want to experiment making my own grow light setup using very high CRI chips and compare that to a high grade LED grow light. Grow light manufacturers are obsessed with efficiency and quality definitely comes as a lower priority...this makes sense because most indoor growers are growing cannabis and being profitable is their main goal. I am going to be growing peppers and vegetables and I am more focused on light quality, I am thinking the closer I can get to mimicking the sun's spectrum the healthier and faster the plants will grow. I know the efficiency of the higher CRI LEDs that have a violet emitter and/or additional phosphors will obviously not be as good as the chips made for horticulture. I won't pretend I know much about this stuff yet, so if I'm mistaken please let me know.
Has anyone here done a similar project, or have any tips or products you would recommend?
I know I have a lot of learning to do, but I like the idea of that. This site has so much information it's hard to know where to get started!
