All the data you find in the chart below are referred to the duration values of the lamps declared from the manufacturers of the lamps and of the led.The energetic values are based on the results calculated on several cemeteries.The values are used only for example and explanation.The maintenance values have been obtained from several analyses made and published by several communal offices. |

COMPARATIVE TABLE BETWEEN TRADITIONAL SYSTEMS AND 3E SYSTEM |
||||||
| Problem | Traditional system | Led system | 3E system | |||
| Disadvantage | Advantage | Disadvantage | Advantage | Disadvantage | Advantage | |
| Presence of tension on the tombs | During the tomb washing mass-dispersions and short circuits .Facilitating of oxidation can be generated | During the tomb washing mass-dispersions and short circuits .Facilitating of oxidation can be generated | There is no electrical feeding but only luminous transport | |||
| monthly and annually maintenance on the tombs | periodic substitution of light bulbs and lamp holders if oxidized. These actions happen more often on the coast areas | periodic substitution of light bulbs and lamp holders if oxidized. These actions happen more often on the coast areas | Substitution of the led after long periods 50.000-60.000 hours |
No electronic components and no lamps are present , only. Optic fiber in plastic material | ||
| Possibility of no-authorized access and substitution to the bulbs | The maintenance is open to everybody. Anyone can replace bulbs or lamp holders with the possible risk of a loss of electrical balance |

| Find out the broken lamp holder | Difficult research on Customer indication | Difficult research on Customer indication | with remote control it is possible to find out the problem immediately | |||
| luminous Intensity | It is not homogenous all life-long among different light points, but only when the system is new | homogenous | best with short distances homogenous with a good planning | |||
| Solar paddles use | Only with large investment systems | With difficult energy distribution system (of difficult management on long distances ) | System able to transform and sell the energy in excess and it is totally independent | |||
| Extra Services | nothing | nothing | Help requests from he guardian or doctor | |||
| Number of maintenance actions regarding traditional lamp | 1/1 | 1/20 | 1/8750 | |||
| Recycle of luminous source | Lost system | Lost system | Lost line, but the lamps can be used again | |||
