Incredible!
Incredible!Been checking the reflectors and the bulbs etc today and thinkingabout Migro video,(led bulb 1.78 umols per watt without the reflector) going to be well over 2.2 with the reflector.
I removed a resister from each of the 8 bulbs and spaced out the bulb holder

And this would make a good veg light, total Watts, (including the fan)51 watt
12" above the meter(Centre) 24,500lux and 16,500 lux sides
Works out 250umols (side) 381umols(centre)
Not the most powerful veg light but I think this will be fine
Max bulb temperature 41c(room temperature 25c), so this is running cool
This will last forever, really amazing results imo, so I have brought over 100 bulbs.
That’s fucking awesome you got it going on hopefully my LEDs will do the trickNot used to giving my plants this much light, the bud growth is great at this stage(1 month in flower, flipped on 3rd

June) few yellow leaves, I have top dressed them a few time.
How tall are those thingsNot used to giving my plants this much light, the bud growth is great at this stage(1 month in flower, flipped on 3rd

The longest colas are about 2ftHow tall are those things
Hungry ladies. No worries, I’m chasing the same issue a bit, although self inflicted.Not used to giving my plants this much light, the bud growth is great at this stage(1 month in flower, flipped on 3rd

Very nice result, could you share some more details, like the wattage of the bulbs, number of bulbs and area they cover. A setup like is is very underrated.These lights can be adequate, I have made something similar, the maps I recorded we're also quite impressive
Hi and thanks, I,m currently growing in a 70cmx70cmx160cm tent and my light fitting is made from fibre board 60cm x 40cm which has a foil coating on one side (they use them for the back of radiators) to reflect the heat, I have only wired in 8 light fittings as this was enough for the space. I change the bulbs over as the grow progresses, so for instance the first couple of weeks I may only have 60watts of light mainly 2700k with a 4000k chucked in too just to broaden the spectrum a little and when the Plants start flowering i change them towards the 4000k spectrum slowly increasing the wattage until harvest.Very nice result, could you share some more details, like the wattage of the bulbs, number of bulbs and area they cover.

Using the bulb diffuse as reflectors and sticking foil to them is not the safest thing to do.
So I have to double check every reflector and use a lowest amp fuse(0.5) i can get away with, I have checked my main fuse box and its all up to date.
The reflectors help the bulbs to penetrate the canopy(could be 60% more) so its not just the amount of light spread at 12"
Going to add side lights to get the light deep in the canopy, I think my leds could match some of the large leds on the market.
time will tell.
Pulls up chair, listens intently.That's amazing, I wish we had more content like this, make sense your a electrical engineer because your using your skills and available parts to build very effective led grow lights, the bulbs I buy in the UK do run hot, but with the airflow in grow room this tends to knock it down from 85 to 65c.
would you say its worth removing a parallel resistor(knocks the temps down another 25-30c) is it likely to last 2-3 times longer or is this wishful thinking? as I don't know loads about electrics but I do a lot of research, last Christmas I built Christmas lights on a breadboard and showed my son how to adjust the speed(delay) color, brightness etc in code(so the program loops), good fun.
I hope its worth removing the parallel resistor, last count, I have 120 new bulbs in boxes, and another 30 laying around, I just hope its not flagged up if I have brought over 200 bulbs in the last 2 months.Pulls up chair, listens intently.
Nah, there are handy men out there who have truck loads. I think you’ll be totally off the radar.I hope its worth removing the parallel resistor, last count, I have 120 new bulbs in boxes, and another 30 laying around, I just hope its not flagged up if I have brought over 200 bulbs in the last 2 months.

That's great to know about the breadboard, Sometimes I would like to leave the UK, things are falling apart.Wow bread boardsnot used one of them since tech, astable, monastable and bistables are the foundation to all electronics, pretty much what you would have done with the Xmas lights. UK... I've only just moved from the UK last year, I'm 50 and lived there all my life (midlands) only moved here as I've retired early and my wife is from here... Resistors? Removing a parallel resistor will increase the current as the resistance drops (ohm's law) so two 100 ohm resistors in parallel make a series circuit of 50 ohms, a diode usually takes approx 0.2 amps or 20 milli amps and the resistors will be calculated against voltage to give you that comfortable window.. I suppose you could play around with them to get a healthy supply and hopefully leading to a longer life but myself Im happy with there performance as they stand, you can mess around and gain let's say 5% but what's that (an extra bulb installed would have the same performance) hope i got your question lol..
I'm back in the UK next month to visit family, shutting myself as I'm leaving my missus to tend to my plants and she hates them lol...
The reflector didn't have a big impact on the temps(6.1w), would effect the 13.3w led, I guess it could increase the temps a little.I guess it’s just controlling any extra heat brought on by the reflector? Or is it pretty much mitigated as is?
