Hello as the title suggest this grow i will be running the phillips 315w LEC lamp in the D-Papillon reflector.
I have created this thread as an easy reference point for people to follow along and see how this light performs.
i hung this light today in a 1m x 1m space and fired it up for the first time. I have to say so far im fairly impressed by what i see. without any light meters or anything the light appears quite bright as is to be expected though. i am using the daylight lamp for veg and it looks to be similar in spectrum to the old phillips mastercolour 400w lamps.
i have noticed there is still a fair bit of flicker with this lamp and ballast similar to running a lamp on an old magnetic ballast as opposed to say something like the solis tek ballast with digital lamps which have almost no visible flicker.
The reflector is quite clever in design and works quite well to distribute heat up and out of the reflector keeping temps quite low. you can really feel the heat escaping from the sides of the reflector
I was also quite impressed by how even the light distribution is under this reflector, i wasnt sure how well it would work with the dual layers in the reflector but waving my phone underneath it with a simple light meter app proved that the spread was quite even across a very flat plane, even right out on the very edges of my space which is a bonus.
another detail well worth mentioning in my opinion is the way in which you can remove the reflective material at any time to give it a clean. it doesnt matter if the lamp is on you simply grab the handle on the front of the unit and pull the reflector out of the main housing, it slides in and out easily. even on my first start up this has already proven very handy as i didnt notice it straight out of the box but my unit was quite dusty, once i started it up it was obvious it needed a clean. i pulled the reflector out and had it cleaned and replaced in around a minute. too easy.

Last round the JTR below took 58 days to finish but were at least 7-10 behind the plants below under the LEC Sun System 315W...
