You state this because you own this: https://xritephotous.com/i1basic-pro-3-open-box/ And you own this: https://babelcolor.com/store.htm And you know how to use both, and you will provide your own measurements.

digitaldog Posted March 2, 2023 Share Posted March 2, 2023 Hopefully, if you are lucky, Sandy or another moderator can help you here as you helped yourself in the other photo forum after you raised this (off) topic: Author “Color Management for Photographers" & "Photoshop CC Color Management" (pluralsight.com) Link to comment Share on other sites More sharing options...
frans_waterlander Posted March 2, 2023 Author Share Posted March 2, 2023 How are the curves on the right SPD curves? Gee, they look very different from the SPD curves for the Sylvania, SoLux and Intertech lamps you posted earlier in this thread (BTW, shouldn't that read Intertek?). Gee, those curves have the dimension of power per wavelength per area. Want to come clean or continue to obfuscate? Link to comment Share on other sites More sharing options...

A primer for you (since you asked a question): http://digitaldog.net/files/15TheRightLightpart1.pdf I appreciate your strong opinion about the SPDs provided, an opinion formed (by your own admission) of having absolutely no experience creating one. Anyway, with respect to Sandy's post here earlier, I think we're done. Since no one here is taking you seriously, and my data provided dismisses your recommendations of this LED as being far from a Solux replacement, and the fact that there are many dozens of Solux bulbs anyone can purchase from just one (of many websites), I don't see the point in illustrating further for others who may land here, the errors of your recommendations. Adiós. Author “Color Management for Photographers" & "Photoshop CC Color Management" (pluralsight.com) Link to comment Share on other sites More sharing options...
frans_waterlander Posted March 2, 2023 Author Share Posted March 2, 2023 Yes, your provided data on the Sylvania LED is much appreciated and I would not recommend that product to anyone for critical print viewing. On the other hand, you raved about an LED lamp that you claimed was the best LED lamp you ever tested. All I'm asking of you is to report the SPD curve for that LED lamp, because what you previously claimed to be the SPD curve/curves for that LED lamp is/are not. Should be simple enough.

digitaldog Posted March 3, 2023 Share Posted March 3, 2023 For others entering this thread for the first or 2nd time, this is highly recommended if you have Apple Mail. Otherwise, if you have specific questions about the data I provided here, I'm happy to address those with open minds to data, facts, and (color) science.

frans_waterlander Posted March 3, 2023 Author Share Posted March 3, 2023 Just the PSD curve, Andrew, so we all can learn. Link to comment Share on other sites More sharing options...
frans_waterlander Posted March 3, 2023 Author Share Posted March 3, 2023 You also may want to look at the Waveform Lighting A19 Color Matching LED lamp; CRI 97 and it's calibrated to meet ISO 3664:2000. Link to comment Share on other sites More sharing options...
