Customer Reviews

I looked every where for this bulb. Found it at


I use it for my Sharper Image air purifier


Macungie PA


T8 Germicidal works great


Buying A/C germicidal bulbs from the A/C repair person is expensive compared to buying an identical bulb through Bulb arrived quickly and in good condition - very well packed to prevent damage.

it hurt my eyes when i had a uv sheild


very good

my youtube is jacobsipod1



Great source for all bulbs!








I own 2 Ionic Air Purifiers that I purchased from a retail Sharper Image store before they closed. In time the germicidal bulbs burned out. I researched and looked high and low to try and find replacemnt bulbs. After exhaustive searches I finally gave up and listened to the naysayers that said these bulbs were no longer available. Then lo and behold I discovered and searched their site and within a few minutes ordered the Phillips germicidal bulbs that fit the Ionic Breeze. The air purifiers were in perfect operating condition but I almost discarded them and would have had to spend hundreds of dollars on replacemnt air purifiers. Thanks to Bulbs.Com I am extremely satsified.

This is just a good product


This is exactly the right bulb for my air filter in a sick room. Finding "" was a stroke of luck, as this bulb was hard to find. [...]It is obviously top quality.

Q & A
HI, Do I need a special ballast for this lamp or will it run on a standard flourescent 15 watt t8 ballast. thanks Ted


Yes, a specific ballast is required. Magnetic LC1420CTP or Lo1322TP with starters or RLQ120TP, HM2SP20TP and Electronic REL2P30G 1L/2L match this Philips germicidal bulb.
