Stanley.Beamish. Posted July 13, 2015 Report Share Posted July 13, 2015 Gloomshade The price quoted to me from my local guy for replacement globes was $180.00.... Yea, hey that's a lot....BUT.......They can last for years and it's said that they will not lose more than 85% of output (May be more as in higher longer life) I know someone will say ...."Yea that's what the salesman said".... . In a few years time with a light meter in my hand I'll let you know..... and then take to my local bloke a couple of Gangster slaps.................. Proof of the pudding my friends...........

Gloomshade Posted July 13, 2015 Report Share Posted July 13, 2015 Yeah to be honest i'll probably just pull my pants down and pay the money. Damn expensive bulbs though... especially for something that can be had for under 100 in the US. Link to comment Share on other sites More sharing options...

Stanley.Beamish. Posted July 14, 2015 Report Share Posted July 14, 2015 Hey young Gloomshade You get what you pay for bros. (To quote an old saying) No...seriously, these lights are the new era of technology..... I'd almost bet my left testicle that my man (forgrtiwashere) is on the ball........Think about it...

itchybromusic Posted July 14, 2015 Report Share Posted July 14, 2015 (edited) prob a good idea to look at hight / space , light output & how much light does a plant need Quick Guide - Lux Levels for Optimal Cannabis Growth < 15,000 lux - sparse or "stretchy" growth - plant isn't getting enough light15,000 - 50,000 lux - good amount of light for healthy vegetative growth45,000 - 65,000 lux - optimal amount of light for cannabis plants in the flowering (budding) stage70,000 - 85,000 lux - a lot of light, some strains do okay at this light level, but some plants lose their top leaves early under this light intensity, especially plants that are not resistant to heat/light (like many indicas)> 85,000 lux - at this light intensity, you've hit the plant's "saturation point" which means your plant can't use all the light (be careful of light bleaching!) http://www.growweedeasy.com/lux-meter I think some of us have to much light me included only recently discovered this by buying a lux meter & checkingjust an opinion Edited July 14, 2015 by itchybromusic Link to comment Share on other sites More sharing options...
Gloomshade Posted July 15, 2015 Report Share Posted July 15, 2015 I'm pretty happy using 315 (340odd) watts per m2. Not sure how many lux the light is spreading accross that m2. But i reckon it would be right where its meant to be. Link to comment Share on other sites More sharing options...

But i reckon it would be right where its meant to be. Not hav'in a go mate but reflection plays a big part as well in increasing light The only way to know is with some sorta meter not say'in you should go out & spend money ,if your happy , your happy & that's the main thingI've just been having a look at all parts of my grow & discovered with the meter i was giving the plantsway to much light ( if you believe the lux chart above )& noticed a diff once i corrected that , can also help withwhen lamps need a change again mate just my thoughts Edited July 15, 2015 by itchybromusic Link to comment Share on other sites More sharing options...
