Yes ...Almost like that ... For our example though some things are different .... Vero 29 is made out of really cheap to produce ( due to GaonSi tech ) LED dies , that feature some new developments ( vertical chips ) ,that actually are not catecorized as " inefficient Chinese blue emitting...

An example ... Vero 29 3000K 80Ra .... At 2100 mA ,it has an Vf of 38 V ( typ ) .... http://www.bridgelux.com/sites/default/files/resource_media/DS33 Vero 29 Array Data Sheet Rev J 20150908.pdf Let us see inside the LES ... 156 chips ... Maybe these ones ...

Under the LES the " excitation " LED chips are connected in certain ways .... Usually a number of diodes wired in series make up a "group ", while a number of these groups ,are wired in parallel .. Than means than when you drive a COB at 700 mA -for example - every each one of its diode chips...

For all the innocent blood spilled ,everywhere in the world " I look like a bombed landscape. Like a blurry verse, at life's last desk And like a migrant bird ... I 'm stubborn and have a strong stomach, like Paul with the phony golden coin the love that I give ,I do not get back as it is...

Why do some guys want still to have some black pepper in their chilli ? Chilli peppers are one thing ... Black pepper is another ... Phosphor Conversion COB LED arrays are made for human vision purposes ... Monochromatic LED units can be used to " pinpoint " certain actions & effects ,in many...

Since we're on " tools " ... NDVI / NRG Plant Health -Photosynthesis Action Camera : https://www.adafruit.com/products/1722#technical-details-anchor http://publiclab.org/wiki/near-infrared-camera http://publiclab.org/wiki/infragram Thermal Camera for 300 Euros / $ 400 ...

A fact. I totally agree . And also for ( almost ) eveything else that is made out of Carbon based polymers .. Few things made out of " plastic materials " are resistant to UV ... Wiring ,piping ,pots ,electric apparatus encasings ,etc will be deteriorating gradually , under the UV radiation...

Kutop HK .... Genuine MeanWell ,no customs fees ,low shipping cost .... http://kutop.com/led-driver/hlg-series/ip65-level-meanwell-hlg-240h-single-output-power-supply-led-driver.html

I can verify that .... A Meanwell HLP 60H-42 is rated as " 1450 mA " driver .... At the test report is stated as " Io max = 1536.8 mA @ 230 VAC " . At real life every each one of them ,is maxing at not less than 1656 mA .... (When the " Io adjust " trimmer is turned fully clockwise )...

Weller and only Weller . ( APEX Tools for the US ) Butane fueled ? No problem ... http://www.amazon.com/Weller-P2C-Butane-Soldering-Iron/dp/B000B61L0G http://www.amazon.com/Weller-P2KC-Professional-Self-igniting-Soldering/dp/B000WOHSHM Your best choice ... Cheers.

My opinion is quite different ... I've come up to the conclusion ,that the UV radiation has a minor positive effect (per growth cycle ) regarding cannabinoid and/or trichome concentration ,while at the same time the negative impact is / can be quite severe. UV radiation should be used only...

HGL-185H has an inrush current of 65 A ( @ 230 VAC ) . 16 x 65 = 1040 A ( !!! ) .. I think no matter what type of circuit breaker / fuse , it will trip .. Furthermore ,it states at the data sheet : MAX. No. of PSUs on 16A CIRCUIT BREAKER : 4 units (circuit breaker of type B) / 7 units...

Zinc plated and inox (stainless steel ) screws ,bolts and washers , are fairly " compatible " with aluminium heat sinks ,regarding galvanic corrosion . Cheers.

Those aluminium heat sinks of yours ,soon will be rendered useless ,regarding their cooling potential .. Direct contact of Aluminium with Copper ,in a humid environment ? Rather bad idea ... http://aluminumsurface.blogspot.gr/2009/04/corrosion-between-anodized-aluminum-and.html...
