Shhhhhh he'll hear you and be out from under that bridge in a flash of green funk, trolling your steam punk @ss

Good question @Kuifje76

Check mate I believe :) (he types, whilst squirrelling away trying to prove Doer wrong!)

I'm sure you know this.....but just in case, you can get LEDIL compatible holders that slip onto the COB holders.....just took delivery. Am based in Europe and Arrow USA sent them to me with free shipping!! If you're in Europe and want either the Chip-Lok COB Holder or the Reflector attachment...

Let me just caveat that by saying I just realised the drivers (LPC-60-1400) are non-dimmable.......so I believe I just answered my question. Would still love an answer if I had dimmable drivers. (currently face-planting my desk at my error).

@Positivity you sir have created possibly the only example of a purist positive vibe thread I've had the pleasure of reading on this forum. Congratulations. I reckon it's because the detailed facts are light and your infectious tinkering is simple and almost "naive" in its approach, though of...

Wunderbar and thanks again - looking at my diagram, it's amazing how proud someone as artistically challenged as I am can be of a crappy diagram like that ;)

Forgive me, but do you mean like this?

Ladies and Gentlemen (well I hope there are ladies here......would be kind of nice), The final parts arrived and I am now in construction mode. Whilst this goes on (and I ask my terribly handy father-in-law to beat the complexity out of my design) I have a final question. If I have 8...

Good grief! I just spent the better part of 10 days working my way through a set of designs that will see me create a 275 x 305 panel made up of strips of 2700/5000 RP from Intematix (fingers crossed....I think they might be sending them to me on a "sample" basis!!!!). Now I stumble across...

Here is something that appears to do the required job - used for 2 hours a day at midday it could be interesting, though a trifle expensive and not DIY at all :) total cost €95 ish. Fluorescent Lighting Controller, 24W 550mm T5 UVA 30%/UVB 12% and a reflector as well with IP67 rating on the...

I am in no way skilled enough to give advice sorry :), but glad you're chucking ideas into a pot that somebody else MIGHT be skilled enough to pass judgement on. This is a forum and thank the Gods of Skunk that we have people to guide us here :)

Oooops someone has angered the grumpy specialists.

Quick question - is anyone powering multiple drivers off of one AC plug? Just wondering if anyone has done this and whether separating each driver to its own AC plug is a better idea.

(that was kinda my point ;) )

The sheer propensity for getting this wrong reminds of those never remembered early pioneers in poison gas development

You're absolutely right....and I have to stand corrected.....UVB is not included. However, I will say in my defence, that the margin for error on emitted nm can be quite high and therefore in trying to attain UVB with a 30nm potential for moving easily to UVC is "frightening". In the words of...

I am growing non-marijuana plants and something about UVA/UVB makes me think it's necessary - the chemistry in plants that we rely on is (according to numerous sources) reliant on a number of factors, and they aren't all positive, so UV stress is surely essential. Who knows. The only way to...

Am thinking of using UVA / UVB LEDs at good power (photon density) for 2 hours a day either side of noon. If you calculate the angle of sun vs time of day vs time of day (something I have for various locations in my attempt to prove that it's almost impossible to hit your vitamin D requirements...
