Should MH bulb show light after power up?

[AngryJohnny]

or does it need time to start light up for first time?

it reads
"time should be allowed for lamps to stabilize in color when turned on forthe first time. this may require several hours of operations, with more than one start.
lamps may require 10 to 20 minutes to re-light if this is a power interuption. "

Yes, they need a warm-up period, although if they are working properly, you should see a dull glow when you first energize them, which gradually brightens over several minutes. HPS lights act the same way, as you can see in any parking lot at dusk.

well 4 hours now. no go no light no nothing...

its normal for the burn glossy look around the bottom they say...

well my little girls are stuck with flouros little longer now...

if you have had your light on for four hours and its not burning dude its trash......get a new one.....my mh lights is very VERY dim for a few mins and gets extremely bright by no more than 5 mins of being turned on...PEACE

brand new bulb, shipped 7-8 days ago will be Thursday next week before a replacement gets here.

I swapped to other socket, still no go... its a dual spectrum box.

HPS works tho.. Philips SON-T 600w

You first were asking about a MH light but you showed a HPS bulb. What type of transformer do you have MH or HPS. HPS requires an igniter along with the capacitor to light up.

I just want to make sure everyone is on the same page.

[AngryJohnny]

[AngryJohnny]

I figured out what the problem is!!
I was sent 2 HPS bulbs. 1 600w and 1 400w :confused:

the 400w bulb does work. its not broken. :rolleyes:


still need a MH bulb. :mad:

[kingcanabis]

if thats not the fix then look in to your starter in that bulb's balest.........it's a big cap..look's like a small pop can.....

[latewood]

I couldn't really tell for sure from your pic's, but are you handling your bulbs with your bare fingers(thought I saw fingerprints), if you are do, it is possible the oil will cause a hotspot and they will blow

[AngryJohnny]

nah, no fingerprints.. used a towel.

its actually a MH conversion bulb they say. operates on HPS ballasts.


4 days behind now... :(
