what exactly was wrong, the lm/W from cree or the "calculated" efficiencies/PPF from forum members?
Well it kept on coming in below spec (compared to citi and vero) in cobkits tests and also under spec in ChilLeds sphere tests. Not sure where the problem was, but it didnt mmeasure up to datasheet, nor in lumens nor in par.

name one led product from respectable companies from the last 3 years which specs didn't match up with real life measurements
It's been suggested that Meanwell drivers are another..

You guys living in spec sheets really need to use practical data you yourself have captured from the field... my original comment that got quoted was in good fun but I'll go ahead and put the cynical engineer hat on for ya too if ya like :bigjoint:

engineers are the only true scientists left. theories and data sheets are not science.lol

cree states for the 3590 3500k cd bin which chilledled tested a minimum flux @ 2400mA and Tj @ 85°C of 12000lm and 13237lm @ 25°C (calculated value). in the chilledled sphere test they tested them at 12467.11lm @ 2400mA and 25°C ambient (no Tj temps provided). where exactly did the spec sheet not match here with the RL measurements?




the only thing that did not match were the numbers provided by the famous @SupraSPL excel sheet everyone were basing their designs on when they underpowered the chip

The rep told me gen 3 ánd gen 4 are hitting the market at the end of Q2 so i'm very disappointed because he first say that gen 3 was ready at the end of last year.
If you get another chance to ask your friend please enquire about gen2 Vesta strips. I dont know why they arent more common around this forum, i mean nearly 200 decent diodes in 90 cri for around 10$?
