any info on the Evolve EV700 available

[justsmokedope]

hi im trying to do a bit of a tare down on the new Evolve EV700 there's very little info on their web site about them .
the leds look like lm301b 2700k and 6500k not sure on the cri and poss osram oslon ssl 660nm reds

ive taken an educated guess on the leds but i think i'm somewhere near
the 660nm reds seem to be run off the 2 2.65a meanwell drivers but at 500ma i think and those leds can go upto a max of 1000ma
am so wondering if the samsungs are being run at a softer level also , maybe this is as its a run cool light
if they are doesnt this mean you could crank these up 2 11 with some slightly different drivers and poss cooling

i'm also trying to figure out how many of each led there are i think there is

134 6500k
103 2700k
12 660nm

on each pcb so times 10 for a full light

also im thinking that this is the reason for the 4 drivers 3 of the being different and 2 x 36v and 2x 42v drivers

this clustering technique is something i've been thinking about for a while and its nice to see it works in practice

Why do you think they are using 301b? I was looking at this companies lights yesterday. Nice controllble units but very over priced IMO.

A link or pic would definitely be valuable in getting proper answers/opinions.

Ooooh steenslands using those.

 

[justsmokedope]

this is a good vid showing them

 

[justsmokedope]

also growmau5 took a look at them too

thats why im planning on making the same my self as the leds are like 4p each
i was playing with this idea any way but was not sure if i was going to make a chilled board type light with clusters or a bar . this option would be alot cheaper as its mainly lm301b leds with only 12 osrams per pcb would prob only cost about £20-30 per pcb

ive tried to count the leds but still not sure how many there are , there is prob a way to work it out using the size of the drivers and the voltage of the leds

i recon that most of the stuff in the evolve is off the shelf stuff it should be relatively easy to reproduce like the heat sinks with covers and the v slot not hard to get

They are using Nichia last I heard.

 

[justsmokedope]

does any one know what 660 red s these are im guessing oslon ssl 80 perhapes but could be anouther lens

 

[justsmokedope]

They are using Nichia last I heard.

so not lm301b they must look identical do you know what nichia product code / led thay are so i can checkout a data sheet

 

[Stephenj37826]

I don't. Probably 757 single die.

ive just had a quick look the only ones that look simular are the
NJSW172B
but they have the black marks on the front the ones in there light does not seem to have them

 

[justsmokedope]

I don't. Probably 757 single die.

thanks found them just looked at both the samsung has slightly better numbers but only just they are 757 Nichia i think as on the pics you can just make out the notch in the corner
are the 660nm red also Nichia then ?
are the Nichia s lots cheaper then ?

 

[justsmokedope]

looking at if i attempted to make these could use lm302c there loads brighter more voltage though

The layout of the strips on this fixture goes against the belief (prevalent on this forum) that for greater uniformity, the strips should actually not be equidistant from each other. Hmm... Interesting.

the clustering seems to solve the low par at the edges of led lights
i supose you could also do this by driiving leds at the edges more than the others or using brighter high power leds at the edges

not sure how your seeing Samsung better?
Samsung cal says 3000k 80 CRI at 40Deg C in AZ volt bin is 35.1lumens, Nichia at same spec is 35.2 Lumens, as they have a lower forward volts

These are really great lights. I really like these guys. The pcbs have to be multi channel for dialing the spectrum you want, more red/blue, etc. They are pricey but they seem to be making an industry impact commercially. I am sure these are similar to the ChilLed pcb approach.

Nope, actually not if you look closer.
I like the fact that the diodes at the strip ends are spaced more tightly together to get a more even coverage. It's the same as we do when we use the "logharhymical" layout. First time I've seen this on a commercial light.
