it will be funny to see how many company's copy Mike from GLH idea. just remember he was the first to do this!!

I was just talking to my friend and he's taking credit for questioning HGL as to why there was a glass cover and she said moisture or something. I remember him mentioning the heat issue to me too with the LED's because of the huge heat sinks and fans. Hopefully that will improve things it should. You would figure any light loses something through glass or anything.

Personaly I think it won't harm a thing... I think it will be a lot like taking the glass off the HID reflector.. Nice.

ya i seen a test and the glass on the HID light blocked like 15-30% light, dont quote me i cant remember all the details? but it was enoff to where it made a difference on the light meter. i know what i can see from my eyes with it off and i know it should be even more because their cretin things we cant see with out eyes. even if it as little as 10-15% oh well that 10-15% more light for my girls, but i truly think its more light then that IMO. but who knows, all i know my girls are lit up better for sure and i have better foot print and penetration. good enoff for me.lol

he can take the credit for asking cammie. but i know Bot and Mike were the first to do this that i know of. he is the one who also told me that the leds would burn my ass if i touched the bulbs without the glass. not true.

He told you to pee on them too so I wouldn't take what he says about LED's to heart..LOL..hey maybe that's why cammie put the glass there..LOL

hey ..how far off the plants do you have your light? also ... the screws on the outside of the case facing in ... i think there are 6 or 8 of them ... could you have not simply unscrewed those and pulled the case in 2 pieces then simply push the glass out?

i have the light 18"" from the plants. idk i could have probably unscrewed it and took it apart, but throwing a spark plug at it was funner and probably faster. i didnt want to unscrew and pull things aprt and mess with things. its was no trouble or harm braking the glass.

Hey Irish, great journal. Finally had a chance to read it all the way through. Plants are looking great for 28 days of flowering. I have some AK-48 under 1000 watts of t-5 VHO and they don't look as good as yours. I hope to get my journal started in the next week or so. These journals take a lot of work and energy so kudos to you and plus reps.

Just a couple of FYI's In a previous life I had a glass business. Ordinary window glass lets about 90% of the light above 350 nm (visible light), but blocks over 90% of the light below 300 nm (that is UV) but even that 10% of UV that is left is enough to fade stuff or give you a mild sunburn. Laminated glass stops 100% of UV and more visible light then normal glass. That 10% of visible light that regular glass blocks is quite noticeable to the human eye and really noticable to plants. That is why mirrors only reflect around 89% of light and mylar and even flat white paint reflect around 95%. On a mirror the visible light has to pass through glass twice.

LED's do produce heat. Just not where you can touch it at the lens. The heat is generated on the circuit board where the light is produced and the design moves it away. The lens are designed not to pick up much heat. That is why LED traffic signals are a problem in snowy places. No heat to melt the snow off the lens like a regular incandescent bulb.
